Special Part
Cardiovascular System (Systema cardiovasculare) – General Overview
Arteries – Introduction to the Hemomicrocirculatory Bed (HMCB)

The GHMCR (Hemomicrocirculatory bed) is an anatomical and functional complex of Blood microvessels that directly supply blood to Organs and Tissues, facilitate transcapillary exchange, and remove Metabolic waste products.

Blood and Lymphatic microvessels are Components of the body's general microcirculation, which encompasses all transport and exchange processes at the microscopic level. Therefore, alongside BLOOD AND Lymph Circulation, microcirculation also includes extravascular circulation—the movement of tissue fluid and the intracellular translocation of fluids.

The GHMCR includes the following segments of The Cardiovascular system: arterioles, precapillaries, capillaries, postcapillary venules, collecting venules, and arteriovenous anastomoses (AVAs) (Fig. 3).

The GHMCR in functionally distinct organs exhibits specific morphological features tailored to the Structure and function of those organs. Blood Circulation within the GHMCR segments is regulated by the muscular components of arterioles and specialized structures known as precapillary sphincters. Ultimately, blood flows from the GHMCR segments into Veins, and subsequently drains via the inferior and superior venae cavae into the right atrium.

The activity of The Heart and other compartments of the cardiovascular system is directed toward ensuring balanced blood circulation within the exchange microvessels (capillaries and postcapillary venules).
