Multiple Choice Questions

Increased erythropoietin production Increased heart rate Increased cardiac output Enhancement in oxygen extraction The answer for this question is b. increased heart rate. A reduction in tissue oxygenation as happens in anemia stimulates increased production of erythropoietin through a complex feedback mechanism. Increased production of erythropoietin enhances erythropoiesis in anemia. Increased extraction of oxygen in anemia is a compensatory mechanism that is mediated by an increase in 2, 3-diphosphoglycerate concentrations. Increased cardiac output is the main hemodynamic compensatory mechanism in anemia that aims to increase blood flow to the body organs. An increase in heart rate ...

The Interdependency of the Digestive System, Respiratory System, and Cardiovascular Systems

In the supply, of nutrients and the removal of waste products in the human system, four organ system are involved; the digestive system, the circulatory system, respiratory system and excretory system. The digestive system comprises of the mouth, stomach, small intestine and the liver.

The digestion of the carbohydrate begins in the mouth. The predominant carbohydrate is the starch. In the mouth, enzyme salivary amylase hydrolyses the starch to disaccharides and trisaccharide.
