WebStructure of Capillary Wall • Composed of unicellular layer of endothelial cells surrounded by a basement membrane • Diameter of capillaries is 4 to 9 microns • Solute and water move across capillary wall via intercellular cleft (space between cells) or by plasmalemma vesicles (Caveolae) WebOct 12, 2024 · Capillary Structure Capillaries are very thin, approximately 5 micrometers in diameter and composed of only two layers of cells. The inner layer is made up of endothelial cells with an outer layer of epithelial cells. They are so small that red blood cells need to flow through them single file.
