  1. The Human Heart

  2. right atrium (in older texts termed the "right auricle") is one of four chambers (two atria and two ventricles) in the humanheart. It receives deoxygenatedblood from the superior and inferiorvena cava and the coronary sinus,and pumps it into the right ventricle through the tricuspid valve.

  3. left atrium is one of the four chambers in the humanheart. It receives oxygenatedblood from the pulmonary veins, and pumps it into the left ventricle, via the bicuspid valve.

  4. right ventricle is one of four chambers (two atria and two ventricles) in the humanheart. It receives de-oxygenatedblood from the right atrium via the tricuspid valve, and pumps it into the pulmonary artery via the pulmonary valve and pulmonary trunk.

  5. left ventricle is one of four chambers (two atria and two ventricles) in the humanheart. It receives oxygenatedblood from the leftatrium via the mitral valve, and pumps it into the aorta via the aortic valve.

  6. aorta (pronounced "ay-OR-tuh") is the largest artery in the human body, originating from the left ventricle of the heart and bringing oxygenated blood to all parts of the body in the systemic circulation.

  7. pulmonary artery The pulmonary arteries carry blood from the heart to the lungs. They are the only arteries (other than umbilical arteries in the fetus) that carry deoxygenated blood.

  8. Pulmonary veins The four pulmonary veins carry oxygen-rich blood from the lungs to the left atrium of the heart. They are the only veins in the post-fetal human body that carry oxygenated (red) blood.

  9. septum is the wall of tissue that separates the right and left atria of the heart.

  10. The inferior vena cava (or posterior vena cava) travels up alongside the abdominal aorta with blood from the lower part of the body. It is the largest vein in the body

  11. The superior vena cava (or anterior) is above the heart, and forms from a convergence of the left and right brachiocephalic veins that contain blood from the head and the arms.
