Document Summary
Cardiovascular system: blood (reading material: chapter 20: pages 530-541) Composed of intercellular substance (fluid but doesn"t have the fibers associated with connective tissue) and cells. Transports: from lungs to all cells of body and carbon dioxide back to lungs: nutrients from gi tract, waste products back to kidneys, lungs, and sweat glands, hormones (secreted by endocrine glands, regulatory substances: enzymes. Regulates: regulates ph through its buffering capacities: body temperature through its heat absorbing and cooling properties of its water content. Protects: against blood loss through its clotting mechanism: protect us from getting sick, important in body"s immune and defense systems. Viscosity: about 4. 5-5. 5 viscosity: blood flows 4 to 5 times slower than water, and is. Temperature: around 38 degrees c ph: 7. 35-7. 45, slightly alkaline, and has salt concentration of 0. 9% Volume: around 8% of body weight: 5-6l in males, 4-5l in females. Formed elements (45% of the blood): cells and cell-like contents.
