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.
The most gas exchange occurs in the capillaries as the pressure there is low. The hemoglobin (protein in the red blood cells) is more loosely bonded to oxygen where the pressure is lower. The pressure is lower in the capillaries because the walls are thin ,and because the pressure dissipated as the blood moved from the arteries (very pressurized).
