- 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.arrow_forwardWhich of these statements about intrapulmonary pressure and intrapleural pressure is true?A.The intrapulmonary pressure is always subatmospheric.B.The intrapleural pressure is always greater than the intrapulmonary pressure.C.The intrapulmonary pressure is greater than the intrapleural pressure.D.The intrapleural pressure equals the atmospheric pressure.arrow_forwardWhich of the following would be most likely to cause pulmonary congestion?
