The peripheral chemoreceptors that respond to oxygen levels of the blood and regulate heart activity are located in
Select one:
a. structures near the carotids and aortic arch.
b. the infundibulum of the hypothalamus.
c. the left ventricle.
d. the right ventricle.
e. the medulla oblongata.
During exercise, venous return is enhanced by:
A. the operation of carotid arterial and femoral arterial valves.

C. skeletal muscle pump operation
D. Answers B and C are correct.
After 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.
