Describe the body's 3 immune systems (Active, Passive, Natural) and how each helps prevent diseases and infections I

Explanation:

Active - the process of exposing the body to an antigen. Exposing the body will generate an adaptive response that takes a few days or weeks to develop and can be life long lasting.

Passive - it is provided when we are given antibodies to disease. Instead of producing the antibodies with the immune system, they are given. Like a newborn baby acquires immunity from the placenta.

Natural - it works to fight off pathogens before they begin an active infection. Sometimes it is not enough to stop the pathogen or the pathogen exploits the immune response and gets to the cells.

fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges. the core principle of fluid balance is that the amount of water lost from the body must equal the amount of water taken in.

this is true my friend.
