Document Summary

Homeostasis and body fluid compartments: physiology is the study of the normal functioning of a living organism and its component parts. External environments: respiratory, digestive, urinary, and reproductive: homeostasis is the ability of the body to maintain a relatively constant internal environment.

The initial stimulant triggers a response, which will then decrease the stimulant, causing the loop to stop: a response, which cancels/counteracts the initial stimulants, triggers a stimulus which goes to the receptors in the integrating center (cns). This in turn triggers an effector, which loops back to the response: - intracellular fluid is the fluid inside the cell (cytoplasm) Extracellular fluid is the fluid outside the cell (plasma, interstitial) Controls expression of genes and preserves dna integrity. Centrioles: structures that direct the dna movement during cell division.
