Capillary. Coloured scanning electron micrograph (SEM) of a section through a capillary,the smallest type of blood vessel. Red blood cells (erythrocytes,red) are seen in the capillary. Capillaries permeate body tissues,forming a mesh between arteries and veins. Their walls are very thin and permeable,allowing gases and nutrients to diffuse through them to the tissues in which they are required. Magnification unknown | |
