The microcirculation is the circulation of the blood in the smallest blood vessels, the microvessels of the microvasculature present within organ tissues.
The blood vessels are the part of the circulatory system, and microcirculation, that transports blood throughout the human body.

Circulatory system

The microcirculation is the circulation of the blood in the smallest blood vessels, the microvessels of the microvasculature present within organ tissues.
The systemic circulation can also be seen to function in two parts – a macrocirculation and a microcirculation.

The microcirculation is the circulation of the blood in the smallest blood vessels, the microvessels of the microvasculature present within organ tissues.
Microvessels are the smallest blood vessels in a body, including those responsible for microcirculation.

Metarteriole

meta-arteriolesmetarterioles
The microvessels include terminal arterioles, metarterioles, capillaries, and venules.
A metarteriole (or arterial capillary) is a short microvessel in the microcirculation that links arterioles and capillaries.

Arteriole

arteriolesarteriolararterial
The microvessels include terminal arterioles, metarterioles, capillaries, and venules. In the pre-capillary sector, arterioles and precapillary sphincters participate.
An arteriole is a small-diameter blood vessel in the microcirculation that extends and branches out from an artery and leads to capillaries.

Capillary

The microvessels include terminal arterioles, metarterioles, capillaries, and venules.
Lymph capillaries connect with larger lymph vessels to drain lymphatic fluid collected in the microcirculation.

Venule

The microvessels include terminal arterioles, metarterioles, capillaries, and venules.
A venule is a very small blood vessel in the microcirculation that allows blood to return from the capillary beds to drain into the larger blood vessels, the veins.

Precapillary sphincter

In the pre-capillary sector, arterioles and precapillary sphincters participate.
A precapillary sphincter is a band of smooth muscle that adjusts blood flow into capillaries mainly in the mesenteric microcirculation.

Microcirculatory Society

Microcirculatory Society
The Microcirculatory Society, Inc. was the first scientific society founded to promote research and teaching in the field of microcirculation.

Transcytosis

The third capillary exchange mechanism is transcytosis, also called vesicular transport.
Transcytosis is prominent in brain microvascular peptide and protein transport, because the brain microvascular endothelium, which forms the blood-brain barrier (BBB) in vivo, expresses unique, epithelial-like, high resistance tight junctions.

Vein

Arterioles carry oxygenated blood to the capillaries, and blood flows out of the capillaries into the venules into the veins.

Lymph capillary

In addition to these blood vessels, the microcirculation also includes lymphatic capillaries and collecting ducts.

Oxygen

The main functions of the microcirculation are the delivery of oxygen and nutrients and the removal of carbon dioxide (CO 2 ).

Pericyte

Most vessels of the microcirculation are lined by flattened cells of the endothelium and many of them are surrounded by contractile cells called pericytes.

Smooth muscle

The vessels on the arterial side of the microcirculation are called the arterioles, which are well innervated, are surrounded by smooth muscle cells, and are 10-100 µm in diameter.
