Body system function: The function of the immune system is to defend your body against cells that could cause diseases such as cancer or maybe just the common cold. The immune system isn't perfect though there are still symptoms you could get for the immune system protecting your body. Some systems may be a fever, swelling, and a runny nose. There are other different symptoms for other different scenarios like if you get cut with a knife your the immune system would react differently. There's also symptoms for allergies like if you're allergic to a cat or pollen.

Organs: Some organs that are from the immune system are the phagocytes, lymphocytes, and lymph nodes. Phagocytes is a type of white blood cells also known as leukocytes that chew up invading germs. Then there's another type of leukocytes/white blood cells called lymphocytes which remembers what type of germs invaded and to regocnize if it has invaded before. Lastly there's something called lymphnodes which is filters out all the germs that could make you sick. Lymphnodes can be found beside your neck, your knees, and your armpits, etc.There is also bone marrow and your spleen which is an organ that filters your blood.

One organs structure and function: Leukocytes/white blood cells helps defend your body from germs that can make you sick. There are 2 types of leukocytes/white blood cells which are Phagocytes and lymphocytes. Phagocytes are a white blood cell that chew up invading germs then there's lymphocytes. Lymphocytes help you recognize a germ or virus that your body has faced before. The lymphocytes is kind of like the brain of the immune system because it remembers the germs that you have faced before and remembers a new germ so if you face it again your body knows how to defend against it.

Interactions with other systems: The immune system works with the circulatory system, the lymphatic system, and the integumentary system. The immune system works closely with the circulatory system for transportation because the immune system needs to make sure every organ and tissue in your body isn't sick. Then there's the lymphatic system which works with the immune system because the lymphatic system creates lymphocytes to defend against germs. Lastly the immune system works with the integumentary system which is also your skin. Your skin defends against germs when you touch things which means it's your first line of defense against germs.

Analogy:

Analogy explanation: The immune system is similar to clorox wipes because clorox wipes clean germs off of surfaces. Then the immune system kills germs in your body with leukocytes/white blood cells. Once you're done with the clorox wipe you can throw away the used one and get another one. Then the immune system filters germs when they are trying to get into your body and make your sick.

Redesign: If I could redesign the immune system I would redesign how much white blood cells/leukocytes are created to destroy the germs. We could redesign the immune system so if there are a lot of germs then a lot of leukocytes/white blood cells will be created. Then if there isn't that many germs then not that many leukocytes/white blood cells will be created.
