- Blood Vessel Length
- Nitric Oxide
- factors that remain relatively constant in vascular resistance
- Where are Capillaries found?
- a Blood viscosity, and blood vessel length.
- b The longer the vessel, the greater the resistance encountered.
- c In all tissues except for cartilage, epithelia, cornea and lens of eye.
- d NO - is a brief but potent vasodilator. Decrease BP.
- e Pressure wave caused by the expansion and recoil of elastic arteries. Varies with health, body position, and activity.
5 Multiple choice questions
- The stickiness of the blood due to formed elements and plasma proteins.
- Blood viscosity, total blood vessel length, blood vessel diameter.
- Smooth muscle and elastic fiber layer, regulated by sympathetic nervous system.
- First sound heart measuring blood pressure, normally 110 - 140 mm Hg.
- 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
When is Angiogenesis common in the heart? → In the Aorta.
Fenestrated Capillaries → Have large fenstrations and intercellular clefts for the greatest permeability, even allowing passage of blood cells.
Vascular (venous) sinuses? → Specialized, flattened veins with extremely thin walls (e.g., coronary sinus of the heart dural sinuses of the brain).
What is directly proportional to Blood Flow (F)? → Blood hydrostatic pressure gradient. - If P increases, BF speeds up.
Inflammatory Chemical → EX - Histamine - vasodilator, decreases BP.
