Physio Exam 3 Questions With Accurate Answers. Describe the Frank-Starling law of the heart - answerThe Frank-Starling law of the heart states that the stroke volume is directly proportional to the preload; an increase in EDV results in an increase in Stroke volume. The EDV is the amount of blood in the ventricles directly before the ventricles begin to contract so it can be referred to as the preload. Stroke volume is also directly proportional to the contractility of the heart in that wh...

Describe myocardial remodeling and disease progression. Ventricular chamber enlarges and pressures increase increasing tension in ventricular muscle wall. High systolic pressures in the ventricle to overcome high afterload (arterial HTN, AV Stenosis). Describe pathophysiology and clinical manifestations of left-ventricular failure. Ineffective pumping results in pulmonary congestion. Backward effects: Dyspnea on exertion, orthopnea, cough, paroxysmal nocturnal dyspnea, cyanosis, basilar ...

Biology 235 Final Exam Questions With 100% Correct Answers 2024/2025 What is afterload with regards to artery anatomy? - answerElastic arteries - stretch and recoil during pressure pulses Amount of elasticity determines force of afterload How do arterioles affect afterload? - answerProvide vascular resistance and regulate regional blood flow via sympathetic vasomotor tone and pre-capillary sphincters What 4 mechanisms regulate blood pressure in the body? - answerBaroreflex Chemoreceptor ...

Coronary artery perfusion is dependent upon: A. diastolic pressure B. systolic pressure C. afterload D. systemic vascular resistance (SVR) A. diastolic pressure Diastolic pressure in the aortic root is higher than left ventricular end-diastolic pressure (LVEDP), the pressure exerted on the ventricular muscle at the end of diastole when the ventricle is full. This enables blood to flow from a higher pressure through open arteries to a lower pressure, a pressure gradient known as coronary...
