Solution

The correct option is B Pulmonary veins
  • The human heart has four chambers two auricles and two ventricles. The right auricle and ventricle receive deoxygenated blood from the superior and inferior vena cava.
  • The left auricles receive the oxygenated blood from pulmonary veins after oxygenation from the lungs which drains into left ventricles.
  • The left ventricles pump the oxygenated blood by aorta which distributes the blood by breaking into arterioles and artery.
So, the correct answer is option A.
