- factors that aid in venous return
- Elastic (Conducting) Arteries
- What is Systolic Pressure?
- Antidiuretic Hormone
- a Respiratory pump, muscular pump and vasconstriction of veins under sympathetic control.
- b Pressure exerted on arterial walls during ventricular contraction.
- c High blood pressure, sustained elevated arterial pressure of 140/90 or higher. May be transient adaptations during fever, physical exertion, and emotional upset. Often persistent in obese people.
- d Thick walled arteries near the heart. Act as pressure reservoirs - expand and recoil as blood is ejected from the heart.
Conduct blood from the heart into Muscular Arteries.
- e (ADH)-(Vasopressin) - Causes intense vasoconstriction in cases of extremely low BP. Increases BP.
5 Multiple choice questions
- Distal to elastic arteries, deliver blood to body organs, have thick tunica media with more smooth muscle, active in vasoconstruction to adjust the rate of blood flow; Distribute blood to Arterioles.
- (MAP), average pressure in the arteries.
- Causes BP to drop by inhibiting ADH.
- The friction between blood and blood vessel walls.
- Small-diameter arterioles.
5 True/False questions
the three important sources of vascular resistance → The friction between blood and blood vessel walls.
funciton of Capillaries → lack pores and have a intercelluar clefts that allow only diffusion of water and small solutes.
Nitric Oxide → Small arteries that lead into capillary beds; controls blood flow into capillary beds by vasodilation and vasoconstriction; Deliver blood to capillaries.
Tunica Media's function → Smooth muscle and elastic fiber layer, regulated by sympathetic nervous system.
What does Atherosclerosis effect? → Pressure exerted on arterial walls during ventricular contraction.
