Blood

It is a circulating connective tissue in the body, composed of plasma and formed elements. It performs material transport, as well as vital and regulatory functions. Arterial blood – oxygen-saturated. Venous blood – carbon dioxide-saturated. Defibrinated blood – artificially depleted of fibrinogen. Used for laboratory tests. Peripheral blood – circulating outside blood-forming organs. Placental blood – fetal blood circulating in placental blood vessels. Fasting blood – a stimulus for the hunger center, as it contains reduced levels of certain nutrients. Rh negative and Rh positive blood – absence or presence of the Rh factor in its erythrocytes. Cadaveric blood – blood taken from a suddenly deceased body. Used in the production of blood transfusion products. Artificial blood – a general term for blood substitutes that modulate basic blood functions (oxygen and nutrient transport, maintenance of acid-base balance, removal of metabolic byproducts).
