Blood Peripheral

Peripheral blood - what is it and what is it needed for?

Peripheral blood, peripheral blood, also known as peripheral blood, is an important part of the circulatory system, responsible for providing the body's cells with oxygen, nutrients, and hormones. Peripheral blood consists of small blood vessels that form the peripheral capillary system. Peripheral capillaries are responsible for transporting blood to all cells of the body. Thus, peripheral blood plays an important role in maintaining homeostasis.

Suitable environment for hematopoiesis

So, the main difference between peripheral blood and central blood is the absence of “staging” of organs and blood. The blood in the capillaries (systems of small blood channels) moves smoothly and calmly, allowing oxygen cells to pass into the arteries and veins. It is important to consider that in the peripheral circulatory system there are many variable factors, including the number of red blood cells, platelets and leukocytes: * The first blood known to us, that is, before birth, is absent; * A few hours after birth, the number of red blood cells in the peripheral system decreases; During the first seven to ten days, the number of zero leukocytes in the peripheral system is restored. Reasons for changes and rules for collecting peripheral blood The reasons that cause a violation of a number of parameters of peripheral vascular blood are different and, accordingly, determine the peculiarities of working with peripheral sampling of blood vessels. In addition, it should be noted that, despite the high diversity of the composition of the peripheral fence, the essence and principles of operation remain unchanged. Features of the composition of peripheral blood The composition of peripheral blood is based on the following factors: * Hemoglobin indicators: With increasing height and weight, hemoglobin indicators in peripheral blood increase. Hemoglobin in peripheral blood becomes less in people suffering from anemia, in whom oxygen saturation of body tissues decreases. Hemoglobin levels in humans depend on diet. If the percentage of protein in food is small, then the volume of hemoglobin decreases;
