35 views11 pages

Document Summary

The digestive tract absorbs nutrients from food, and the liver adjusts the nutrient concentration of the circulating blood. The cardiovascular system delivers these nutrients, along with oxygen from the respiratory system, to peripheral tissues. As blood leaves these tissues, it carries the co2 and other waste products generated by active cells to the sites of excretion. Most of the organic waste products, along with excess water and electrolytes, are removed and excreted by the urinary system. In times of o2 deficit, the kidneys will secrete erythropoietin to produce more rbcs which will increase the efficacy of o2 transport to cells in need. Low blood pressure stimulates renin secretion renin will convert into angiotensin ii which is a potent vasoconstrictor. Renin is an enzymatic hormone that triggers a chain reaction which is important in salt conservation, as well as arterial pressure and volume control.
