Series of events that occur in the heart during one heartbeat g Sounds that are produced when the heart valves close h. Cydlic expansion and contraction of the arteries 7. Stethoscope 8. Korotkoffsounds- 9. Pulse 10. A woman's blood pressure at rest is 125/75. After 30 minutes of exercise, her blood pressure is 190/80. Calculate her pulse pressure and mean arterial pressure (MAP) at rest and after exercise. a. b. How did her pulse pressure and MAP change after exercise? . During exercise, why do you think there is a large increase in systolic pressure, but very itle chang in diastolic
Explanation / Answer
Arteries are a type of blood vessels thar are responsible for carrying blood away from the heart. This means that, the blood is oxygenated, and is usually pumped at a high pressure by the heart. In order to withstand the pressure exerted by the blood on the walls of the arteries, the tunica media of the arteries are considerably thicker as comparated to the veins.
They also possess higher amoung of elastic tissue and smooth muscle fibers.This allows for better modulation of the caliber and diameter of the blood vessel, which is necessary for maintaining a constant blood pressure throughout the entire system.
