- Antidiuretic Hormone
- Systemic Blood Pressure
- Nitric Oxide
- a Endothelial layer that lines the lumen of all vessels.
- b (ADH)-(Vasopressin) - Causes intense vasoconstriction in cases of extremely low BP. Increases BP.
- c NO - is a brief but potent vasodilator. Decrease BP.
- d Blood flow caused by the pumping action of the heart, pressure results when flow is opposed by resistance.
- e Occurs when short term autoregulation cannot meet tissue nutrient requirements. Either the number of vessels to a region increases or existing vessels enlarge.
5 Multiple choice questions
- The longer the vessel, the greater the resistance encountered.
- Pressure exerted on arterial walls during ventricular contraction.
- ANP - Causes blood volume and pressure to decline (produced by atria of the heart0.
- It is easily changed by altering blood vessel diameter.
- Vasoconstriction/vasodilation of vessels.
5 True/False questions
Autoregulation → Automatic adjustment of blood flow to each tissue in proportion to its requirements at any given point in time.
Where does Systemic Pressure decline? → Throughout the pathway.
Chronic Hypotension → Hint of poor nutrition and warning sign for Addision's disease (adrenal isnsufficiency) or hypothyroidism.
Fenestrated Capillaries → Have large fenstrations and intercellular clefts for the greatest permeability, even allowing passage of blood cells.
Where are Capillaries found? → Endothelium with sparse basal lamina.
