Document Summary
Open circulatory system: a circulatory system in which fluid called hemolymph bathes the tissues and organs directly and there is no distinction between the circulating fluid and the interstitial fluid: ex: Closed circulatory system: a circulatory system in which blood is confined to vessels and is kept separate from the interstitial fluid: ex: Lymphatic system: a system of vessels and nodes, separate from the circulatory system, that returns fluid, proteins, and cells to the blood. Cardiovascular system: transport of gases between environment and tissues (oxygen to tissues, carbon dioxide from tissues, transport of nutrients and metabolic waste products, defence immune system. Hemophilia disease: excessive bleeding and bruising from even minor cuts and bubs. Thrombus: blood clot within a blood vessel: anticlotting factors in blood normally prevent spontaneous clotting in absence of an injury. Thalassemias: reduction in synthesis of a or b globins: a-thalassemia most common in asian populations, b-thalassemia most common in mediterranean populations.
