- When is Angiogenesis common in the heart?
- a Occurs when short term autoregulation cannot meet tissue nutrient requirements. Either the number of vessels to a region increases or existing vessels enlarge.
- b Hint of poor nutrition and warning sign for Addision's disease (adrenal isnsufficiency) or hypothyroidism.
- c Neural and hormonal controls - counteract functuations in blood pressure by altering peripheral resistance.
- d Continuous capillaries, Fenestrated capillaries, sinusoidal capillaries (Sinusoids).
- e A coronary vessel is occluded, throughout the body in people in high-altitude areas.
5 Multiple choice questions
- 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.
- Increases resistance and disrupts blood flow to cause turbulence.
- The stickiness of the blood due to formed elements and plasma proteins.
- In all tissues except for cartilage, epithelia, cornea and lens of eye.
- Reflects two factors of the arteries close to the heart. The elasticity (compliance or distensibility), and the amount of blood forced into them at any given time.
5 True/False questions
Vital Signs → 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.
Veins → 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.
Tunica Interna (Innermost) → Smooth muscle and elastic fiber layer, regulated by sympathetic nervous system.
Capillaries → 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.
