Analysis and Description of Hematologic System

The Hematologic System is regarded as the body’s system that regulates the movement of nutrients, molecules (macro and micro molecules), and oxygen to tissues and metabolic waste products and carbon dioxide out of the tissues (Colbert, 2009). The overall role of the hematologic system is to deliver substances needed for cellular metabolism, temperature regulation, defend the body from injury and microbial infections, and maintain the homeostatic balance or acid-base chemistry of the blood and fluid-electrolyte balance. The Hematologic System is principally made up of the blood, blood vessels, and primary organs that manufacture blood cells such as the bone marrow, spleen, lymph nodes, liver, and thymus gland (Ignatavicius & Workman, 2009). Blood is made up of three distinct components: red blood cells, white blood cells, and plasma, and its role is to transport necessary substances for metabolism (nutrients, hormones and oxygen) to cells and to remove metabolic waste products and carbon dioxide, regulation of body temperature and fluid balance, and protect the body from infections. Blood vessels simply aid the transportation of blood throughout the body, simply in and out of the heart. Spleen on its part is the largest lymphatic organ and functions as the blood filtration system and reservoir, site for fetal hematopoiesis, and mounts immune responses that act against invading infections. Bone marrow is another important component of the hematologic system, and its role is to synthesize new blood cells (Red blood cells white blood cells, and platelets) that constitute a healthy blood count while the liver functions by detoxifying the blood (Colbert, 2009).

...ulation respectively. In terms of assessment, hemophilia is suspected in children with excessive bleeding, easy bruising, spontaneous hematuria, and epistaxis (Ignatavicius & Workman, 2009). A low prothrombin and bleeding and low factor VIII in indicative of hemophilia A while an extended thromboplastin time and low factor IX is indicative of hemophilia B. Hemophilia is a lifelong disease and treatment regimens are aimed at reducing the signs and symptoms associated with it. Type A and B are managed with supplementation plasma concentrate Factor VIII and factor IX respectively, liver transplant, and gene therapy (Colbert, 2009).
