Key Concepts & Definitions

  • Heart: A muscular organ approximately the size of a fist that pumps blood throughout the body via rhythmic contractions.
  • Atria: The two upper chambers of the heart (right and left) that receive blood returning to the heart.
  • Ventricles: The two lower chambers (right and left) responsible for pumping blood out of the heart to the lungs and the rest of the body.
  • Right Atrium: Receives deoxygenated blood from the body through the superior and inferior vena cavae.
  • Right Ventricle: Pumps deoxygenated blood into the pulmonary arteries toward the lungs.
  • Left Atrium: Receives oxygenated blood from the lungs via pulmonary veins.
  • Left Ventricle: Pumps oxygenated blood into the aorta to supply the body; it has the thickest muscular wall due to high workload.
