Anemia disease

Blood is one of the main components in the human body. It performs vital functions, through which ensured the unity and maintaining homeostasis in the body.

Blood consists of a liquid component, called plasma, and a cellular mass. The largest percentage of cellular elements in the blood falls on the erythrocytes (red blood cells). They bind oxygen from the air and carry it to all the cells and tissues of the body, thus maintaining their normal life cycle.

Erythrocytes are small double discs that have no nucleus and are relatively plastic membrane. They originate from a progenitor (stem) cell in the bone marrow, which is then repeated becomes differentiated into mature erythrocytes. Typically, erythrocytes live about 120 days, after which they occur various morphological changes, and they are destroyed by the cells of the reticuloendothelial system. But thanks to a finely maintained regulatory system in a healthy organism, the number of erythrocytes always remains constant, which provides the oxygen needs of the cells.
