A capillary is a small blood vessel, from 5 to 10 micrometres in diameter, and is part of the microcirculation system. Capillaries are microvessels and the smallest blood vessels in the body. They are
A simplified illustration of a capillary network
Transmission electron microscope image of a cross-section of a capillary occupied by a red blood cell
Types of capillaries: (left) continuous with no big gaps, (center) fenestrated with small pores, and (right) sinusoidal (or 'discontinuous') with intercellular gaps
Scanning electron micrograph of a liver sinusoid with fenestrated endothelial cells. Fenestrae are approximately 100 nm in diameter.
Blood vessels are the tubular structures of a circulatory system transporting blood in animal bodies. Blood vessels transport blood cells, nutrients, and oxygen to most of the tissues of a body, and a
