Answers
Answer:
We are all familiar with many of the organ systems that comprise the body of advanced animals: such as the circulatory system, nervous system, etc. More of us are aware of the essential nature of the immune system in these days of HIV, AIDS, and emergent viral diseases such as Ebola and Hanta. Later chapters will focus on animals, such as sponges that have no organs at all, and other organisms that lack many of the organ systems we take for granted. Recall that in the Introduction chapter we discussed the levels of organization we see in biology, from atoms to organ systems that makeup a multicellular organism. We have also seen somewhat of the myriad cells and tissues that occur in humans (and by extension in other animals). This chapter will introduce you to the eleven organ systems that function within our own bodies, and how they coordinate to keep us functioning within a dynamic range of internal conditions we refer to as homeostasis.
