D. The blood travels to the lungs to get carbon dioxide.

Pyr0manical
Has to be A,
B makes no sense since the liver produces bile
C makes no sense because the oxygenated blood cells are supposed to release the oxygen wherever it was supposed to go
and D makes no sense because our muscles probably wouldn't be functioning with carbon dioxide.

The blood returns to the heart through veins is the next step of the blood circulation process.

what are veins?

Veins are the blood vessels which carry  blood towards the heart.

what is blood circulation?

The pumping motion of the heart causes blood to flow through the body's veins, distributing nutrients and oxygen to all regions of the body while also removing waste materials – see pulmonary circulation and systemic circulation.

steps of blood circulation:-

  • The right atrium is where the blood first enters.
  • The blood subsequently goes into the right ventricle via the tricuspid valve.
  • The ventricle sends blood through the pulmonic valve into the pulmonary artery when the heart beats.
  • The pulmonary artery transports blood to the lungs, where it is oxygenated.
  • The blood then exits the lungs and returns to the heart via the pulmonary vein.
  • Blood flows into the left atrium.
  • It enters the left ventricle through the mitral valve.
  • The left ventricle then pumps blood into the aorta via the aortic valve. The aorta is the main artery that supplies blood to the rest of the body via a network of blood vessels.
  • The superior vena cava and the inferior vena cava are two big blood arteries that return blood from the body to the heart. Because this blood is returning from the body, it has very little oxygen.
  • The vena cava pumps blood back into the right atrium, restarting the cycle.

so the correct option is A.
