Capillaries are the smallest types of blood vessels. They have a diameter of around five to 10 micrometers and the thickness of the endothelial lining is only one layer of cell. When all blood vessels are combined, they reach a length of almost 100,000 km (60,000 miles) with the capillaries making up 85 percent of the length.


Capillaries are the smallest and most fragile of the body's blood vessels. They are responsible for what is known as microcirculation, meaning that they create a circulatory network within the organs of the body. There are three different types found in the human body: continuous, fenestrated, and sinusoidal.


Sinusoid capillaries (also known as a discontinuous) are a special type of open-pore capillary, that have larger openings (30–40 µm in diameter) [citation needed] in the endothelium. These types of blood vessels allow red and white blood cells (7.5 µm – 25 µm diameter) and various serum proteins to pass, aided by a discontinuous basal ...


There are three main types of blood vessels: This vast system of blood vessels -- arteries, veins, and capillaries -- is over 60,000 miles long. That's long enough to go around the world more than ...


There are three major types of blood vessels: the arteries, which carry the blood away from the heart; the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from the capillaries back toward the heart

types of capillaries. STUDY. ... Blood vessels between arterioles and venules that pass through capillary beds but are not true capillaries. Like arterioles, these vessels ahve smooth muscles present in the tunica media that allows it to act as a shut to regulate blood flow in the true capillaries that branch from it.


There are 3 types of capillary in the body; continuous, fenestrated, and sinusoidal. Continuous. As their name suggests, continuous capillaries have a continuous endothelial lining. They have tight junctions between their endothelial cells along with intercellular clefts through which small molecules, like ions, can pass.

Sinusoidal: Sinusoidal capillaries are a special type of fenestrated capillaries that have larger openings (30–40 μm in diameter) in the endothelium. These types of blood vessels allow red and white blood cells (7.5μm–25μm diameter) and various serum proteins to pass using a process aided by a discontinuous basal lamina.
