Which parts of the heart receive blood from the lungs? A. Right ventricle B. Left atrium C. Left ventricle D. Right atrium

Right ventricle
Left atrium
Left ventricle
Right atrium

The correct answer is: B. Left atrium

The left atrium is a chamber of the heart that receives oxygenated blood from the lungs. The left atrium is located in the upper left portion of the heart. It is separated from the right atrium by the interatrial septum. The left atrium is connected to the left ventricle by the mitral valve.

The left atrium is a muscular chamber that contracts to pump blood into the left ventricle. The left ventricle is the chamber of the heart that pumps oxygenated blood to the rest of the body.

The left atrium is a vital organ that plays an important role in the circulation of blood.

The other options are incorrect because:

  • The right ventricle receives deoxygenated blood from the right atrium.
  • The left ventricle pumps oxygenated blood to the rest of the body.
  • The right atrium receives deoxygenated blood from the body.
