Blood circulation Collateral

Blood circulation is the movement of blood through the vessels, ensuring the supply of organs and tissues with oxygen and nutrients (mainly in the tissues) and their utilization of metabolic products. This process is carried out thanks to the work of the human cardiovascular system. Poor circulation leads to cardiovascular diseases.

Blood vessels are divided into arteries and veins, the latter also called venous arteries. According to the blood flow, arteries are distinguished - aorta, vessels of small, medium and large caliber. In direction - veins of large and small caliber. Also, there is a third type of vessels - capillaries. The peculiarity of their structure and functioning is that they have

Collateral circulation is such blood circulation when blood from the main bed enters vessels located on the periphery.

Blood supply to organs and tissues is carried out through arterial vessels. The arteries that arise from the aorta are called the main arteries. Smaller arteries called tributaries branch off from them. The tributaries branch into even smaller arteries called ramifications. The branches, in turn, can branch into even smaller branches. Thus, the arterial system is a network of vessels that provide blood supply to all organs and tissues.

However, sometimes it happens that the main vessel cannot deliver enough blood to a certain organ or tissue. In such cases, blood supply can be provided through collaterals. Collaterals are lateral branches from the main vessels that allow blood supply to an organ or tissue, even if the main vessel is damaged or blocked.

Collateral circulation is a very important mechanism for maintaining the life of the body. It allows for sufficient blood flow to organs and tissues even in the event of damage or blockage of the main vessels. Collateral vessels can be both large and small, and can be located at different levels of the vascular system.

In addition, collateral circulation can be used to treat vascular diseases. For example, if there is stenosis (narrowing) of the main vessel, collaterals can help increase blood flow to the organ or tissues, which can improve their function and reduce symptoms of the disease.

Thus, collateral circulation plays an important role in maintaining the life of the body and can be used as a therapeutic method for vascular diseases.
