Biology Assignment
The maintenance of homeostasis is of major importance to all organ systems in the body and the overall survival of the individual. Explain how homeostasis is the maintenance of a dynamic range of environmental qualities rather than holding the internal environment at a set point. What would be wrong with a set point (say for body temperature) rather than a working range of temperatures?
The endocrine system is closely tied to homeostasis functioning. Give two examples of hormones (including their glands of origin and action) that play major roles in homeostatic processes in the body. What happens if these hormones are disrupted in their actions?
Also, look at how we adapt to survival in the outside world. Discuss how maintaining homeostasis gives us greater freedom of activity from dependence upon changes in the external environment. What happens during extremes that force our bodies out of homeostatic bounds? Give specific examples.
Why is the maintenance of homeostasis especially important during development of new humans within the bodies of their mothers? What can go wrong if specific homeostatic functions are disrupted?
Which of the following immune system cells is the target of the human immunodeficiency virus? a. cytotoxic T cells b. neutrophils
