Capillaries are so small that red blood cells can only travel through them in single file. Capillaries measure in size from about 5-10 microns in diameter. Capillary walls are thin and are composed of endothelium (a type of simple squamous epithelial tissue). Oxygen, carbon dioxide, nutrients, and wastes are exchanged through the thin walls of the capillaries. Capillary Microcirculation. Capillaries play an important role in microcirculation.
There are three mechanisms that facilitate capillary exchange: diffusion, transcytosis, and bulk flow. Capillary Exchange Mechanisms. Diffusion, the most widely-used mechanism, allows the flow of small molecules across capillaries such as glucose and oxygen from the blood into the tissues and carbon dioxide from the tissue into the blood.
