Cardiovascular System — Flashcards

Cerebral blood flow is autoregulated extremely well between arterial pressure limits of _____ and 140 mm Hg

_____ rhinitis occurs due to parasympathetic overactivity which causes vasodilatation and congestion.

The second phase of Lewis' triple response is _____ which occurs due to arteriolar dilatation, secondary to axon reflex

When resistances are arranged in _____, the pressure through each level of the system is the same

Standing up and the valsalva maneuver are both used to _____ pre-load

Activation of _____ adrenergic receptors causes coronary and skeletal muscle vaso-dilation

The _____ function curve is a plot of the relationship between cardiac output of the left ventricle and pressure of the right atrium

_____ is a good approximation of left atrial pressure

An increased blood volume (or venous tone) causes the cardiac output to _____ and right atrial pressure to increase

The _____ function curve is a plot of the relationship between pressure of the right atrium and venous return
