    A nurse is reviewing the anatomy of the heart chambers and valves with a patient diagnosed with valvular heart disease. Based on your knowledge of cardiac anatomy and function, which of the following pairings between heart chambers and their correct names are accurate? (Select all that apply)

    Explanation & Rationale

    A. Right ventricle pumps deoxygenated blood into the pulmonary artery through the pulmonic valve is correct because the right ventricle sends deoxygenated blood to the lungs for oxygenation. Blood flows from the right ventricle through the pulmonic (pulmonary semilunar) valve into the pulmonary artery. B. Left atrium receives oxygenated blood from the pulmonary veins is correct because oxygenated blood returns from the lungs via the pulmonary veins and enters the left atrium before passing through the mitral (bicuspid) valve into the left ventricle. C. Right atrium receives deoxygenated blood from the body via the superior and inferior vena cava; Tricuspid valve located between the right atrium and right ventricle is correct because systemic venous blood enters the right atrium through the vena cavae, then flows through the tricuspid valve into the right ventricle. D. Left ventricle pumps oxygenated blood into the pulmonary artery; Aorta receives deoxygenated blood from the right ventricle is incorrect because the left ventricle pumps oxygenated blood into the aorta, not the pulmonary artery. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs, while the aorta carries oxygenated blood from the left ventricle to the body.
