PTA NPTE Exam (Cardiovascular/Pulmonary) | UPDATED
Questions with 100% Verified Answers
Question: Apex
Answer:
lowest part of heart formed by inferolateral part of the left ventricle
Question: Base
Answer:
Upper border of heart involving the LA, RA, and proximal greater vessels
Question: Endocardium
Answer:
Endothelial tissues lining the interior chambers and valves
Question: Myocardium
Answer:
Thick contractile Middle layer of muscle cells that form the bulk of the wall
Question: Epicardium
Answer:
Serous layer of pericardium that contains epicardial coronary arteries and veins, autonomic nerves, and
lymphatics
Question: Pericardium
Answer:
Double walled connective tissue sac that surrounds the outside of the heart and the great vessels
Question: Aorta
Answer:
Largest artery and central conduit of blood from the heart to the body. Begins in the upper left ventricle,
descends into the thorax (thoracic aorta), then into the abdominal cavity ( abdominal aorta)
Question: Superior vena cava
Answer:
Vein returns venous blood from the head neck arms to the R atrium
, Question: Inferior vena cava
Answer:
Veinr eturns blood from the lower body to RA
Question: Pulmonary Arteries
Answer:
carry deoxygenated blood to the R ventricle and L and R lungs
Question: Pulmonary veins
Answer:
Cary oxygenated blood from the lungs to the left atrium
Question: Blood Flow path
Answer:
Venous blood from Superior and Inferior vena cava enters RA, Tricuspid valve, Closes, RV contracts into
pulmonary valve, trunk, then arteries to RL lungs, Oxygenated blood returns to LA, Mitral valve, LV
contraction to the aortic valve, body
Question: Sinoatrial node
Answer:
pacemaker of the heart and part of the cardiac conduction system along with the Atrioventricular node
Question: Barorecepter Reflex
Answer:
Mechanoreceptors that detect change in pressure
Question: Bainbridge reflex
Answer:
Are on the walls of the RA and when stretched by venous return increase heart rate
Question: chemoreceptor reflex
