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.
Report Abuse. 1  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. 2  Gas Exchange occurs in the capillaries that branch off from the arteries. The capillaries touch cells and oxygen inside blood cells exit the capillary and enter the body cell while carbon dioxide exits the body cell, travels through the capillary wall and enters the blood cell.
