Question

Which of the following statements describes the path of blood entering into the heart?

A. Blood enters the heart through the pulmonary vein, into the right atrium, through the tricuspid have to the right ventricle.
B. Once the right ventricle is full, blood exits into the pulmonary artery and then empties into the left ventricle.
C. After traveling through he lungs, oxygenated blood enters into the left atrium, then through the mitral valve to the left ventricle.
D. Once the left ventricle is full, the left tricuspid valve shuts, the ventricle contracts, and blood exists through the aorta.

Answer 1

Blood enters the heart through the pulmonary vein into the right atrium, then through the tricuspid valve to the right ventricle. Oxygenated blood enters into the left atrium, then through the mitral valve to the left ventricle. Once the left ventricle is full, the left tricuspid valve shuts, the ventricle contracts, and blood exits through the aorta.

Step-by-step explanation:

The correct statement describing the path of blood entering into the heart is: Blood enters the heart through the pulmonary vein, into the right atrium, through the tricuspid valve to the right ventricle.

After traveling through the lungs, oxygenated blood enters into the left atrium, then through the mitral valve to the left ventricle. Once the left ventricle is full, the left tricuspid valve shuts, the ventricle contracts, and blood exits through the aorta.
