- factors that remain relatively constant in vascular resistance
- Vital Signs
- Elastic (Conducting) Arteries
- a Automatic adjustment of blood flow to each tissue in proportion to its requirements at any given point in time.
- b Pulse and blood pressure, along with respiratory rate and body temperature.
- c Blood viscosity, and blood vessel length.
- d 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.
- e 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.
5 Multiple choice questions
- Endothelium with sparse basal lamina.
- (MAP), average pressure in the arteries.
- Endothelial layer that lines the lumen of all vessels.
- ANP - Causes blood volume and pressure to decline (produced by atria of the heart0.
- Vessels of the vessels - larger veseels contain this. Nourish the external tissues of the blood vessel wall.
5 True/False questions
Systemic Pressure in the right atrium → 0mm Hg.
What is Blood Flow inversely proportional with? → Peripheral Resistance (R). - If R increases, blood flow decreases.
Diastolic Pressure → When sound disappears is recoreded, usually 70 - 80 mm Hg.
Alcohol → Causes BP to drop by inhibiting ADH.
Blood Vessel Length → The longer the vessel, the greater the resistance encountered.
