Document Summary
Cardiovascular system: blood (reading material: chapter 20: pages 530-541) Specialized connective tissue composed of intracellular components and cells. Transports oxygen from lungs to body cells, co2 from cells back to lungs, nutrients transports from cells, waste products to sweat glands, hormones secreted by endocrine glands to target cells. Regulate ph via buffering, normal body temp via heat absorbing and cooling properties regulates of water content, protects against the loss of fluid via clotting, protects. Therefore blood will flow 4 5times slower to viscosity water in part due to its viscosity. temperature ph. Counts for about 8 % of body weight. 5-6 litres in adult male, 4-5 litres in female. Formed elements (45% of the blood): erythrocytes (red blood cells): non true cells (no nucleus) no internal structures so cannot reproduce. Lack of mitochondria means all oxygen carried goes to peripheral tissues not for intracellular activity. Relies on anaerobic metabolism using glucose from plasma.
