Inward folding of a membrane
WebMacropinocytosis or ‘cell drinking’ is a type of endocytosis that involves the nonspecific uptake of extracellular material, such as soluble molecules, nutrients, and antigens. First observed in 1931 by Warren Lewis while working on rat macrophages, macropinocytosis was described as the inward folding by some of the cell surface ruffles to fuse with the … WebThis problem has been solved!

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.
