WebProteins transporting ions or other molecules across the membrane, whose proper concentration is required to maintain homeostasis, perform very sophisticated biological … WebIntercellular slits in the capillary membrane have a diameter of about 7 nm which is much larger than the 0.12 nm radius of a water molecule. Because the total surface area of the body's capillaries is huge (6,300 m 2) and their walls are thin (1 mm), the total diffusional water flux across the capillaries in the body is very large indeed.
WebWhat is phagocytosis? Phagocytosis is a process by which cells ingest large particles (> 0.5 micrometers) into membrane-bound vesicles called phagosomes, which are then targeted to the lysosomes for enzymatic degradation.
