- Think of what you have learned about the functioning of the human body? Think of all the amazing things it
can do. Why do you think nutrition underlies so many things? - Why do you think multiple small meals a day is better for your body than a few large meals?
- Why do you think the human body seems to "get used to" whatever kind of food it is eating? Think in terms
of all the different metabolic pathways you have learned about.
Review
- What is the purpose of a monthly self-exam of the testes?
- Explain how girls can reduce their risk of developing toxic shock syndrome.
Summary
The human body. Made of numerous organ systems. Maybe one of the most complex structures ever. But all these
systems and structures come together in an exquisite manner to make a fascinating organism. Currently, the end of
the line of evolution. The most intelligent of all organisms. An organism that can protect itself from pathogens, has
bones for support, muscles to help it move, systems that allow it to respond to the environment, systems to bring
oxygen into and around the body, systems to extract nutrients from food and get rid of wastes, and systems to make
the next generation. And all these systems and organs and tissues and cells work together to form one complete
organism.
