  • The heart is a muscular organ in all living things and pumps blood through the blood vessels.
  • In humans, mammals, and birds, this is a four-chambered, upper left and right atrium, and the lower left and right ventricle. 
  • The deoxygenated blood flows into the right atrium through the vena cava and passes into the right ventricle. 
  • From there, it is pumped into the pulmonary artery and enters into the pulmonary circulation where it gets oxygen from the lungs.
