What is the correct path of blood through the heart, starting with deoxygenated blood returning from the body?
a.Right atrium, tricuspid valve, right ventricle, pulmonic valve, lungs, left atrium, mitral valve, left ventricle, aorta
b.Left atrium, mitral valve, left ventricle, lungs, right atrium, tricuspid valve, right ventricle, aorta
c.Right atrium, mitral valve, right ventricle, aorta, lungs, left atrium, tricuspid valve, left ventricle
d.Right ventricle, right atrium, lungs, left ventricle, left atrium, aorta
Giải thích
Deoxygenated blood enters the right atrium from the venae cavae, passes the tricuspid valve into the right ventricle, leaves through the pulmonic valve to the lungs, returns oxygenated to the left atrium, crosses the mitral valve into the left ventricle, and exits through the aortic valve to the body. The mitral valve is always on the left and the tricuspid on the right, and blood always flows atrium to ventricle, never the reverse.
