When the smooth muscles of the muscular arteries dilate, what happens to (systemic) blood pressure?
Step by step
Solved in 2 steps
- How would “hardening of the arteries” (arteriosclerosis) affect blood pressure? Why?During work, blood flow through a muscle can increase 20 times but the cardiac output does not increase as much, this is because a) vasoconstriction of the skin circulation, at least temporarily b) vasodilation of the blood vessels in the working muscles c) the blood supply to the gastrointestinal tract is reducedWhy does blood pressure decrease as blood flows through the cardiovascular system?
- Does body position affect blood pressure (as measured by pulse pressure)?Changing the radius (diameter) of which of the following blood vessels is the most effective in changing blood pressure? (A) elastic artery (B) muscular artery (C) arteriole (D) capillary (E) medium vein(a) What are the primary forces that cause fluid to move out of a capillary and into the interstitial fluid at its arterial end? (b) What are the primary forces that cause fluid to move into a capillary from the interstitial fluid at its venous end?
- In a blood pressure reading of 120/80, the 120 represents and the 80 represents . (a) diastolic pressure; systolic pressure (b) pulse pressure; mean arterial pressure (c) systolic pressure; diastolic pressure (d) mean arterial pressure; pulse pressureBecause the veins lack the muscular layer that arteries have, what processes are used to move the blood through the veins and back to the heart?Can someone explain why the arteries act as a "pressure reservoir" and why veins act as a "blood reservoir"??
