Anatomy and Physiology II
Polycythemia is a condition characterized by an increased number of red blood cells (RBCs) in the bloodstream, which leads to higher blood viscosity and can impair circulation. This condition affects hematopoiesis, the process of blood cell formation, by driving an overproduction of erythrocytes from the bone marrow, which can occur as a primary disorder or secondary to various physiological stimuli. The implications of polycythemia extend to hemostasis, as the increased blood viscosity may enhance the risk of thrombosis and alter the normal clotting processes.
congrats on reading the definition of Polycythemia. now let's actually learn it.
