Importance of selectively permeable membrane
Witryna14 kwi 2024 · BrM is a 2–4 μm thin layer of extracellular matrix between the retina and choroid in the eye serving as a selectively permeable membrane between the RPE and choriocapillaris (CC). The RPE is a crucial monolayer of epithelial cells supporting the high metabolic activity of the neural retina through various key metabolic, transport, … WitrynaThe permeability of a membrane is dependent on the organization and characteristics of the membrane lipids and proteins. In this way, cell membranes help maintain a state of homeostasis within cells (and tissues, organs, and organ systems) so that an organism can stay alive and healthy.
