PPT-DEFINITION Polycythemia is a blood disorder in which the body produces too many blood

The extra cells cause the blood to be thicker and this in turn increases the risk of other health issues such as blood clots TYPES Primary polycythemia Secondary polycythemia Primary polycythemia is also called polycythemia vera PV. Blood transports materials through out the body inside blood vessels.. Plasma. Straw colored, nonliving part of blood.. 90% Water. Helps to regulate body temperature. Contains Electrolytes. Plasma transports blood cells, products of digestion and hormones throughout the body.. Systems. Vocabulary. Systems. Cell – The smallest living thing that can preform life functions. Tissue – group of similar cells working together for one function. Organ – A group of tissues working together. Definition:. Increased RBCs in the blood.. Secondary polycythemia:. Tissue hypoxia. Failure of oxygen delivery to tissues.. Large amount of RBCs are formed.. RBC count increases to 6-7 million/mm3. Physiological polycythemia. “River of life”. Transports everything that must be carried from one place to another within the body:. Nutrients. Wastes. Heat. Composition of Blood. Blood cells or formed elements:. Red blood cells – transports oxygen. Infants: 73% or more water (low body fat, low bone mass). Adult males: ~60% water. Adult females: ~50% water (higher fat content, less skeletal muscle mass). Water content declines to ~45% in old age. Anatomy Test Review 1 Which component of blood is directly responsible for transporting oxygen to body cells?
