Physiology and function of the tight junction
Webbthis video describes the molecular components of tight junction and their physiological significance WebbPhysiology Final Content Explanation Key words Homeostasis Homeostasis is the maintenance of a stable internal environment, when fluctuations above or below a “set point” occur, homeostatic control systems are in place to bring the value back towards the set point. Thus, although fluctuations occur, they do so within a predictable and narrow …
