- What is Diastolic Pressure?
- What is Systolic Pressure?
- Inflammatory Chemical
- Angiotensin II
- a Small arteries that lead into capillary beds; controls blood flow into capillary beds by vasodilation and vasoconstriction; Deliver blood to capillaries.
- b Kidney release of renin generates angiotensis II, which causes vasoconstriction. Increase BP.
- c Lowest level of arterial pressure.
- d Pressure exerted on arterial walls during ventricular contraction.
- e EX - Histamine - vasodilator, decreases BP.
5 Multiple choice questions
- Low blood pressure, systolic pressure below 100 mg Hg. Often associated with long life and lack of cardiovascular illness.
- 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.
- Peripheral Resistance (R). - If R increases, blood flow decreases.
- The longer the vessel, the greater the resistance encountered.
- Microscopic blood vessels, walls of thin tunica intima, one cell thick. Size only allows one RBC at a time; Permit exchange of nutrients and wastes between blood and interstitial fluid.
5 True/False questions
factors that remain relatively constant in vascular resistance → Respiratory pump, muscular pump and vasconstriction of veins under sympathetic control.
Diastolic Pressure → First sound heart measuring blood pressure, normally 110 - 140 mm Hg.
When is Angiogenesis common in the heart? → In the Aorta.
Vital Signs → Formed when venules converge; Composed of three tunics; Return blood to the heart, facilitated by valves in veins and in limbs.
Vascular resistance → The friction between blood and blood vessel walls.
