Explanation by: Admin

The human heart has four chambers:

  • Two upper chambers called atria (singular: atrium)
  • Two lower chambers called ventricles

The atria receive blood:

  • Right atrium receives deoxygenated blood from the body.
  • Left atrium receives oxygenated blood from the lungs.

Why other options are incorrect:

  • (A) Ventricles – These are the lower chambers.
  • (C) Both A & B – Incorrect because only atria are the upper chambers.
  • (D) None of the above – Incorrect as atria is the right answer.
