NR507 Advanced Pathophysiology 2024/2025. How does blood flow through the heart? Deoxygenated venous blood → Sup. Vena Cava → Right Atrium →Tricuspid (AV) →Empties into R. Ventricle (& it contracts) → Blood ejected through Pulmonary Valve → Pulmonary Artery → Lungs to be Oxygenated → Pulmonary Veins → L. Atrium → Mitral (AV) → L. Ventricle (pumps with each contraction) → Aortic Valve → Aorta → Body What is systole? Contraction of the heart which pumps blood Diast...

How does blood flow through the heart? correct answer: Deoxygenated venous blood → Sup. Vena Cava → Right Atrium →Tricuspid (AV) →Empties into R. Ventricle (& it contracts) → Blood ejected through Pulmonary Valve → Pulmonary Artery → Lungs to be Oxygenated → Pulmonary Veins → L. Atrium → Mitral (AV) → L. Ventricle (pumps with each contraction) → Aortic Valve → Aorta → Body What is systole? correct answer: Contraction of the heart which pumps blood Diastole cor...

Right heart catheterization Pulmonary artery pressure and oxygen saturations may be obtained; biopsy of myocardial tissue may be obtained endocardium inner lining of the heart myocardium muscular, middle layer of the heart epicardium outer layer of the heart tricuspid valve valve between the right atrium and the right ventricle mitral valve valve between the left atrium and the left ventricle; bicuspid valve aortic valve The semilunar valve separating the aorta from the left ventri...

What is the entire pathway a RBC travels throughout the heart/body? - *Starts at vena cava, then heads to the right atrium, then through the tricuspid valve (atrioventricular), then to the right ventricle, then through the pulmonary valve (semilunar valves), then through the pulmonary trunk to get the blood oxygenated, and then comes to the pulmonary veins with oxygenated blood, then goes to the left atrium, then left AV valve (mitral valve;bicuspid), then to the left ventricle, then through the...

PCCN Cardiac Exam 127 Questions with Verified Answers Which of the following is the outermost lining of the heart? A. Endocardium B. Myocardium C. Transcardium D. Pericardium - CORRECT ANSWER D. Pericardium "Endo" meaning "within" is associated with the innermost lining of the heart, so eliminate A. The myocardium is associated with the heart's middle layer, so eliminate option B. The "transcardium" is somewhat of a contrived term, so eliminate C as well. The prefix in pericardium...

contractility - strength of contraction -how effective is heart at squeezing blood out improving contractility - BP is low-> give catelcholamines depressing contractility - BP is high-> beta blockers preload - degree of stretch at END of diastole (relax so filling) -higher stroke volume= more blood returning to heart afterload - resistance of ejecting blood out from ventricle s -more resistance- less stroke volume -vessels dilated- less resistance- easier to leave heart increasing...

Valves of Right and Left Side Right- Tricuspid Valve Left-Bicuspid (Mitral) Valve What happens to valves during diastole Valves are open- Allow blood from atria t flow freely into relaxed ventricles What happens to valves during systole Valves are closed- The ventricles contract and blood flows upward into the cusps of the tricuspid and mitral valves, causing them to close. Name layers of heart from inner to outermost Endocardium Myocardium Epicardium Pericardium- Sac surround heart Automati...
