- During exercise, venous return is enhanced by: A. the operation of carotid arterial and femoral arterial valves. B. the operation of the respiratory muscle/ventilation pump. C. skeletal muscle pump operation D. Answers B and C are correct.arrow_forwardAfter her workout, Arlene lies down on a mat to stretch out her leg muscles. She stands up suddenly after stretching and feels a bit light-headed. However, the lightheaded feeling passes quickly. What physiologic process occurred that resulted in the passing of her light-headed feeling? a. The aortic bodies detected an increase in blood pressure in the head and initiated a chemoreceptor reflex that decreased blood pressure. b. The carotid bodies detected low CO2 and high O2 levels from exercising and stimulated the vasomotor center to vasoconstrict the vessels of the head and neck. c. Only α receptors in the head and neck initially were being stimulated, resulting in the light-headed feeling. d. The baroreceptors within the carotid detected decreased stretch in the carotid vessel wall and initiated an autonomic reflex to increase blood flow to the head and neck.arrow_forwardWhich of the following would be most likely to cause pulmonary congestion?
