Paragraph Styles Name 1. Blood flow (Q) is regulated by: a. Cardiac output b. Heart Rate x Stroke volume c. Mean Arterial Pressure Total Peripheral Resistance (MAP d. Complete resistance to blood flow in the aortic artery TPR) 2. During exercise, the body redistributes blood to sustain exercise intensity. During steady state exercise, blood flow to the brain will be reduced. a. True b. False 3. within blood vessels release nitric oxide (NO) gas to cause a. Endothelial cells, vasodilation of blood vessels b. Endothelial cells, vasoconstriction ofblood vessels c. Endothelial cells, increased exercise performance d. Endothelial cells, increased heart rate Understanding pulmonary structure and function, there are two (2) zones of ventilation. They are the 4. zone and the zone. a. humidification, alveolar b. dead space, regulation d. air transport, particle filtration oe." @ DOLLExplanation / Answer
1.C {Mean arterial pressure/total peripheral resistance(MAP/TPR)}
The most important factor affecting blood flow are mean arterial pressure and vessel radius.
2.False.when you exercise increased activity in your muscles triggers an increased need for oxygen rich blood to meet this demand,heart rate speeds up and blood flow to body including brain increases,but hits increase in blood flow to the brain depends on the intensity of the exercise,that is steady state exercise increases the blood flow to the brain,while intense exercise reduces the blood flow.
3. Endothelial cells within blood vessels release nitric oxide to cause vasodialation of blood vessels.The nitric oxide produced relaxes vascular smooth muscle leading to vasodialation.
4.The 2 zones are dead space zone and the regulation zone.
