Document Summary

Homeostasis: the maintenance of relatively constant conditions in the internal environment regardless of what is happening on the external environment. The endocrine system (slow response) and the nervous. System (rapid response) are involved in maintaining homestasis. Physiology is the biological study of the function of living organisms and their underlying processes. *things are internal until it has been absorbed or reabsorbed (kidneys) *including the entire inside of your digestive system, your lungs. *the controlled variable ends up shutting off the effector. Intracellular fluid compartment (icf): everything inside the cells- 28 l (7. 4 gallons or 67% of tbw) Extracellular fluid compartment (ecf): everything outside the cells: the interstitial compartment: everything outside the cells but not in the plasma- 11l (2. 9 gallons or 26% of tbw, the plasma: 3l (0. 8 gallons or 7% tbw) Na+, ca++ & cl- are found in high concentrations on the outside of the cell. K+ is found in high concentrations on the inside of the cell.
