The given phase is B. Blood is transferred to the lungs for oxygenation and is pumped into various organs simultaneously.

Human Circulatory System:

  • The human circulatory system includes the heart, the blood vessels (arteries, veins, and capillaries), blood and lymph.
  • Humans have double circulation i.e. blood flows through the heart twice to complete one circulation.

Double Circulation in Humans:

  • In humans, the oxygenated blood first reaches the left atrium from the lungs through the pulmonary vein.
  • The atriums then contract and the blood then flows to the left ventricle.
  • Now the atriums relax, and the ventricles contract.
  • The blood is then pumped into various organs via the aorta.
  • At the tissue site, the blood takes up CO₂ and releases O₂.
  • The deoxygenated blood is carried to the left atrium through the veins which then go to the left ventricle.
  • The ventricle contracts and the deoxygenated blood go to the lungs through the pulmonary artery to take up oxygen.
