What Body System Does Cholera Affect Help With A Biology Project On Cholera?

Help with a biology project on cholera? - what body system does cholera affect

I have to draw a caricature of the role of biology. They gave me mad, and we must show how they invade the body and what happens in the body, including immune system defenses. then we must show that wins: the disease or the body. If I could explain what the defenses of the immune system, such as cholera is in the body, it would help me a lot. I am in Grade 10 biology, the simple things. Thank you!
