WebThe cell membrane provides a boundary separating the internal workings of the cell from its external environment. More importantly, it is selectively permeable, permitting the free passage of some materials and restricting the passage of others, thus regulat ing the passage of materials into and out of the cell. WebThis ensures that the tissue will have enough oxygen to support its higher level of metabolism. Maintaining internal conditions in the body is called homeostasis (from homeo-, meaning similar, and stasis, meaning standing still). The root “stasis” of the term “homeostasis” may seem to imply that nothing is happening.
WebHomeostasis is maintained at many levels, not just the level of the whole body as it is for temperature. For instance, the stomach maintains a pH that's different from that of surrounding organs, and each individual cell maintains ion concentrations different from those of the surrounding fluid. WebHomeostasis plays a pervasive role in shaping the form and function of all biological molecules and organisms. Students should be able to explain and apply core concepts of underlying homeostasis, including the need for biological balance, linked steady state processes, quantification of homeostasis, the organization of chemical processes, and …
