Body system function: The function of the digestive system is to help you eat and digest your food. Once food gets into your mouth a process called mechanical digestion which helps turn your food into pulp. Then at that moment your body releases enzymes which then start another process called chemical digestion.

Organs: Some organs that are in the digestive system are the mouth, the esophagus, the stomach, the small intestine, the liver, and the large intestine. First when you eat food your mouth breaks down the food with saliva which has enzymes that help break down the food. Then the food goes down the esophagus which helps the food travel to the stomach. Although all it does is help food get to the stomach it also prevents food from getting into your windpipe. There's something called the epiglottis is like a flap which flaps down to make sure the food goes in the esophagus and not the windpipe. After the food goes to the stomach which also breaks down food but breaks it down so it's a liquidy mixture. The walls of the stomach help it because the walls provide gastric juices to help break down the food. Once the food is a liquidy mixture it goes to the small intestine. The small intestine also breaks down food but just enough so you can absorb all the protein, vitamins, minerals, and carbohydrates. There are also 3 other organs that help the small intestine with its job the pancreas, liver, and gallbladder. The job of the pancreas is to create juices that help digest fats along with proteins. Then the job of the liver is to create a juice called bile which helps you to absorb fats into the bloodstream. The gallbladder works closely with the liver because it stores the bile until the body is in need of it. Soon after there is the large intestine which takes all of the juices your body doesn't use but it's also one more chance to absorb some minerals and water. Lastly all the juices your body doesn't need is turned into waste (poop or pee). The large intestine has help from something called the rectum. When you go to the restroom the waste then travels to something called an anus which results in all the waste going in the toilet.

One organ function: I think the stomach is an important organ because it helps digest your food until it's a liquid. It helps the other organs so it's easier to absorb the protein and nutrients that was in the food. The inside of the stomach releases something called enzymes which breaks down the food into a liquid.

Interactions with other systems: The digestive system works with the circulatory system, the endocrine system, and the excretory system. The circulatory system helps absorb the nutrients that your body needs. Then the endocrine system helps how fast the process of digesting goes in the digestive system. Lastly the excretory system is like a filter that takes compounds from your blood stream which results them in becoming urine (pee). The excretory system also helps control the amount of water that's in your body.

Analogy

Analogy explanation: Composting is just like the digestive system because there's bacteria in the composted food that breaks it down. In the digestive system there's enzymes which breaks down the food you eat. Then the plants that get the compost absorb the nutrients from the soil that was from the composted food. In you body the digestive system also absorbs the proteins and nutrients just like how plants absorb the nutrients from the soil.

Redesign: To make the digestive system better by when you eat a lot you don't have to puke. We could make it better by helping it digest faster. If the digestive system digested food faster if you're about to puke the digestive system can have an emergency supply of energy that helps it digest faster. This way you don't have to go through the mess of cleaning your shirt and you can finish your food in peace.

Body system function: The function of the muscular system is to help you move. The muscular system helps you move your legs and hands. But you can't control the beat of your heart or the smooth muscle that's in your body. The ones you can't control are controlled by the autonomic nervous system.

Organs: First there's the smooth muscle which have layers with one in front of the other. It can also sometimes be called the involuntary muscle and what it does is help your food through your body, then if you need to puke the smooth muscle pushes the food back up through your esophagus, and it also helps you to hold in your urine (pee) and then push it out. Then there's cardiac muscle that makes up your heart. The cardiac muscle is also called the myocardium which helps pump blood out and once the muscle relaxes the blood comes back in. After is the skeletal muscles which is also called striated muscle. The skeletal muscle is a voluntary muscle which means you can control what they do and the skeletal muscle make up the musculoskeletal system. The skeletal muscle helps you get your strength to kick a ball, throw something, and to get up when your sitting.There are also things in your body called tendons which connect your bones and muscles together. Other skeletal muscles that are in your back or near your spine are really important because it helps you stand upright. Then there's also face muscles and the face muscles are what help you make different faces to be surprised, angry, a smiling face, or just a funny face that makes people laugh. Though there are many expressions that your face can make the muscles in your face attach under your skin. Lastly there are some major muscles that you should know about such as the deltoid which helps you move your shoulders like throwing a ball, the pectoralis, the rectus abdominus muscles which are also called abs, the biceps, the quadriceps which become stronger the more you run or go on a bike ride, and gluteus maximus which you sit on when you take a seat.

One organs function: The deltiod is a major organ in the muscular system because it helps you use your arm and shoulder. Some examples are to hit something, throw something, grabbing something, pushing something, and climbing.

Interactions with other systems: The muscular system interacts with the nervous system by helping the food your digestive system move through the intestines. The muscular system helps the food move through the intestines because there's smooth muscle lining the digestive system. There's also smooth muscle in your circulatory system and your lymph system. Since  the smooth muscle is in your body it help controls your body temperature.

Image link: https://en.wikipedia.org/wiki/Shoe

Analogy explanation: I think the shoe is like the muscular system because the shoe helps you move around by helping you go outside just like the smooth muscle helps food go through the digestive system. The shoe is also flexible by adjusting to your foot size and shape after the time when you wear it. The muscular system helps you be flexible and helps you move your hands and feet.

Redesign: We could make the muscular system better by making it more adaptive. If the muscular system is more adaptive it could adapt to when your hot or cold. It could also adapt to if your in space or on earth again. People would be healthier and there wouldn't be excuses for not going to someones birthday.

Circulatory system function: The function of the circulatory system is to transport chemicals throughout your body. The cycle is it starts in your lungs where you get oxygen, then you go to the heart where the oxygen is carried to through the blood in your body, After you go through the arteries which carries blood from the heart, Later you go to the brain, Lastly you go to the veins which carries blood to the heart. Then the cycle starts all over again.

Organs: The organs for the circulatory system are the heart which is like a pump to your body and is a power source to the circulatory system. Then there's your lungs which lets in oxygen to your blood and lets out the air you don't need (carbon dioxide). Then there's your veins and arteries which helps blood move throughout your body.

The hearts function: The heart is the hardest working organ/muscle in your body. If you didn't have a heart you wouldn't have oxygen or blood. You wouldn't have oxygen because when the heart pumps out blood there's some oxygen in it and the lungs take the oxygen for you to breath. The heart is like a power source for the circulatory system/cardiovascular system. The heart works closely with the lungs because when the lungs get the oxygen from the blood the lungs give oxygen to tissues in your body.

Relationship with other systems: The circulatory/cardiovascular system is involved with every system and also organ to distribute oxygen efficiently. But there are also cells in your body that need oxygen as well as fluids that the circulatory system/cardiovascular system has. These fluids are also important to the digestive system as well. There are also hormones that are created by the endocrine system which is then sent throughout your body by the circulatory/cardiovascular system.

Analogy picture: 

Image link: https://en.wikipedia.org/wiki/Natural_gas_vehicle

Analogy explantation: The gas in a car is like the circulatory system because the gas is like the blood in your body and the engine is like your heart. The gas pumps through the car to make it move and the blood in your body helps you breath so you can move. The engine in a car is like your heart because it starts the car and your heart pumps blood for you. Then there are pipes in the car which carries the gas which is also like your arteries and veins. The arteries and veins carry the blood in your body just like the pipes in the car carries the gas through the car.

Redesign: If I could redesign the circulatory system it would be for it to have more protection against diseases and from bruises on your body. I would do this because even though the skeletal system is strong if you break your bones in a car crash you might survive if the circulatory system was stronger. Then if the circulatory system was strong against diseases we would be able to survive longer if we somehow got stranded somewhere.

Skeletal system

Skeletal system

Skeletal system function: 2 main things that the skeletal system does is to protect you and to supports you. The skeletal system protects you by covering your organs to protect them and it supports you like support beams. The skeletal system also you move and have a shape.

Info link: http://www.biology4kids.com/files/systems_skeletal.html or Studios, Andrew Rader. "Skeletons Inside and Out." Biology4Kids.com: Animal Systems: Skeletal System. N.p., n.d. Web. 19 Oct. 2016.

Organs: The skeletal system doesn't have any of those squishy red organs but it does have a lot of different types of bones. One of them is the spine and the spine is made up of 26 bones of total and they're called vertebrae. The spine helps you to be flexible like bend and twist but it also keeps you upright. Next is the Ribs and the ribs keep other organs like the heart, lungs, and your liver. The rib has 12 bones in total but some people have less and some people are born with more bones but normally it will be 12. After is your skull and the skull protects the brain which is the most important of all. There's also something called a suture which connects your bones together.  Then there's your hands and you hands are what give you the availability to hold, touch, and type. It also has bones that help it function such as the scapula, humerus, radius, and ulna. These bones make up and connect the arm. Then if you combine your hands, wrists, and every one of your fingers there are 54 bones in total. After is the legs that help you run, and walk. The legs also have other bones to help it such as the femur, patella, tibia, and fibula. Then if you combine your feet and your ankle you have 52 bones in total. The next organ/bone is the joints and the joints is where 2 bones meet. There are different joints in your body such as the parieto-temporal, the hinge joint, and the ball and socket. Then there's something called ligaments which keeps your bones together like rubber bands.

The spine's structure and function: The spines structure is like a long beam with a bunch of bones and one sharp one on the end of it. If the spine didn't exist then the whole skeletal system would fall apart and it also protects things called spinal cords. The spinal cords transport messages from the brain to different parts of the body so you can do things. It also lets you be flexible like turning around to look at something. It also helps you to bend down and reach for something if it's on the floor or the side.

Relationship with other systems: The muscular system works with the skeletal system because the skeletal system protects the muscular system. The bones in the skeletal system are made of cartilage which helps the skeletal system by making its process smoother. The skeletal system also works with the circulatory system which helps the bones in the skeletal system create red and white blood cells. It creates this because there's marrow in your bones which creates those cells.

Analogy:

Analogy explanation: The skeletal system is like table legs because it helps support your body (the table) by keeping you upright. Then the table legs (the skeletal system) supports the table (your body).

REDESIGN: One way I could redesign the skeletal system is to make it so your bones aren't sore the day after you do something that drains all your energy. The bones in your body are strong but you still get sore after 1 day of maybe football or basketball practice.

Summary: This week I learned more about osmosis, hyper tonic, hypo tonic, and Isotonic. Osmosis is the movement of water molecules going to a higher concentration to a lower concentration of water. Hypertonic is when there's more soul yes outside the cell than inside (More water molecules outside). Hypotonic is when there's more solutes inside the cell than outside (more water molecules inside the cell). Isotonic is when the level of solutes is even inside and outside the cell (the water inside and outside the cell are the same).


SP3: Planning and carrying out investigations
. A major practice of scientists is planning and carrying out systematic investigations that require clarifying what counts as data and in experiments identifying variables.

Did you plan and carry out an investigation?

(Mostly when we do a investigation, lab, or experiment)

I did an egg experiment and me and my group had to record whether the egg was Isotonic, hypertonic, or hypotonic.

Weekly blog 10/9/16

Summary: This week we learned about photosynthesis and respiration. The reactants of photosynthesis are carbon dioxide and water. Then the Products of Photosynthesis are glucose/sugar and oxygen (This takes place in the chloroplast). Reactants are the ingredients of the process and the products is what was created from the reactants. Then for respiration the reactants are oxygen and glucose/sugar. The products of respiration are carbon dioxide, water and also a large amount of energy (This takes place in the mitochondria).

Summary: This week I learned about CHONPS which is carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. I also learned about Carbohydrates which has a monomer called monosaccharide and an example of carbohydrates is starch like potatoes or corn. I also learned about Lipids which has the monomer called fatty acid and an example of Lipids is fats like a candle. Then there's proteins with monomer called animo acids and an example of proteins is meats like beef or lamb but beans also count. Then Nucliec acids has the monomer called nucleotides and an example of Nucliec acids is DNA and RNA.



SP2: Developing and using models
Models make it possible to go beyond things you observe and simulate a world not yet seen. Models enable predictions of the form “if…then… therefore” to be made in order to test hypothetical explanations.


Did you build a model, draw a picture, created a concept map, etc?

I sketched a picture of Charbohydrates, proteins, Lipids, and Nucliec acids.
