Cardiovascular System — Flashcards

The pulmonary circulation is normally characterized as a _____ resistance, high compliance system (low or high)

Phase _____ of the SA node action potential is characterized by upstroke

_____ splitting is heard in conditions that delay aortic valve closure

A hyperkinetic pulse is a rapidly rising pulse with high amplitude due to the rapid ejection of a _____ stroke volume against a decreased afterload

The Frank-Starling relationship states that the force of _____ is proportional to the end-diastolic length of the cardiac muscle fiber

Increased _____ results in an increased width on a pressure-volume loop curve

Closure of the ductus arteriosus occurs in response to increased _____ and decreased PGE (from respiration and placental separation, respectively)

Bradykinin causes arteriolar _____ and venous constriction

ECF volume _____ produces a(n) decrease in capillary hydrostatic pressure (Pc)

AV shunts _____ preload and decrease afterload
