- a A coronary vessel is occluded, throughout the body in people in high-altitude areas.
- b 0mm Hg.
- c Low blood pressure, systolic pressure below 100 mg Hg. Often associated with long life and lack of cardiovascular illness.
- d Pulse and blood pressure, along with respiratory rate and body temperature.
- e Peripheral Resistance (R). - If R increases, blood flow decreases.
5 Multiple choice questions
- Blood flow caused by the pumping action of the heart, pressure results when flow is opposed by resistance.
- Neural and hormonal controls - counteract functuations in blood pressure by altering peripheral resistance.
- ANP - Causes blood volume and pressure to decline (produced by atria of the heart0.
- In all tissues except for cartilage, epithelia, cornea and lens of eye.
- Temporary low BP and dizziness when suddenly rising from a sitting or reclining position.
5 True/False questions
factors that remain relatively constant in vascular resistance → Blood viscosity, total blood vessel length, blood vessel diameter.
Veins → Formed when venules converge; Composed of three tunics; Return blood to the heart, facilitated by valves in veins and in limbs.
What are the major determinants of Peripheral Resistance? → Small-diameter arterioles.
Pulse → Formed when capillary beds unite. Allow fluids and WBC's to pass from the bloodstream to tissues. Collect blood from capillaries and pass it on to veins.
Antidiuretic Hormone → (ADH)-(Vasopressin) - Causes intense vasoconstriction in cases of extremely low BP. Increases BP.
