Question

A disease state results when homeostasis has been disrupted. Give a specific example of a disease state of the organ system you chose (integumentary, skeletal, muscular, nervous). What causes this disruption to homeostasis? How does the body resolve this disease?

Answer 1

To maintain homeostasis, the body must obey the law of mass balance which means that certain substances need to be removed at certain times. They can either be removed by excreting them through various methods or by converting them into different substances using metabolism.

Homeostasis refers to stability, balance, or equilibrium within a cell or the body. It is an body’s ability to keep a constant internal environment. For instance, when the concentration of carbon dioxide in the human body increases, the lungs are signaled to increase their activity and exhale more carbon dioxide, (breathing rate increases). Thermoregulation is another example . When body temperature rises, receptors in the skin and the hypothalamus sense the temperature change. The temperature change (stimulus) triggers a command from the brain. This command, causes a response (the skin makes sweat and blood vessels near the skin surface dilate), which helps decrease body temperature.The maintains homeostasis during thermoregulation by Sweating, shivering, dilation/constriction of blood vessels at skin surface, insulation by adipose tissue, breakdown of adipose tissue to produce heat.
