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 networks of capillaries in most of the organs and tissues of the body. These capillaries are supplied with blood by arterioles and drained by venules. Capillary walls are only one cell thick (see diagram), which permits exchanges of material between the contents of the capillary and the surrounding tissue.he following diagram summarises the sequence of blood flow through the heart, arteries, arterioles, capillaries, venules, veins, then back to the heart: The following diagram summarises the structural differences between different types of blood vessels. More information about this also follows in the next section.
