Document Summary
Physiology: the study of the normal functioning of living organisms and its component parts. The cells in multicellular organisms play critical roles in homeostasis of the organism as a whole. Homeostasis: balance, not a static thing, some normal fluctuations; the ability of the body to maintain a relatively constant internal environment. Self-regulatory process involving all organs, tissues, and cells in the body: need input of energy to maintain homeostasis. Our body is in constant interaction with internal and external environments. Initial stimulus response (receptors-integration center (cns)-effectors) decrease stimulus. Eventually the stimulus will be decreased enough that the loop will stop. Cells within our body are surrounded by interstitial fluid which serves to act as a transition between the external and the intracellular fluid inside the cells. Extracellular fluid: fluid outside the cell (interstitial fluid and plasma. Describe the chemical composition of plasma, interstitial fluid, and intracellular fluid.
