Blood cells Red blood cells (RBCs) Blood cells: Red blood cells, scientifically referred to as erythrocytes, are one of the most essential components of the human circulatory system. These specialized cells are primarily responsible for the transportation of respiratory gases, specifically oxygen and carbon dioxide, between the lungs and various tissues of the body. Produced … Read more
Process of Hemopoiesis Process of Hemopoiesis: Hemopoiesis, also known by the alternative spelling hematopoiesis, is the dynamic and intricate biological process through which the body continuously generates new blood cells. This vital physiological process ensures the constant renewal and replacement of blood cells that are essential for oxygen transport, immune defense, and blood clotting. The … Read more
Hemopoietic system Hemopoietic system: The hematopoietic system—also spelled haematopoietic system—is an essential and intricate biological system responsible for the continuous production and renewal of blood cells throughout an organism’s lifetime. This system encompasses various anatomical sites and cellular processes, primarily operating within the bone marrow, but also involving lymphatic organs such as the spleen, thymus, … Read more
Blood groups: In the year 1900, Austrian scientist Karl Landsteiner discovered the ABO blood group system. In his experiments, he mixed different blood types, observing that the plasma from specific blood types produced agglutinates or formed clusters. This phenomenon was caused by the absence of molecules on red blood cells, which, in turn, led to … Read more
Mechanisms of coagulation: Blood coagulation, or clotting, is a complex and tightly regulated physiological mechanism that prevents excessive bleeding following a vascular injury. It involves a series of sequential and interrelated reactions that ultimately lead to the formation of a blood clot. The coagulation process can be divided into three main pathways: intrinsic, extrinsic, and … Read more
