1. Heart Chambers and Roles

Key Concepts & Definitions

  • Right Atrium: receives deoxygenated blood from the body via the superior and inferior vena cavae. It acts as the entry chamber for blood returning to the heart from systemic circulation.
  • Left Atrium: receives oxygenated blood from the lungs through the pulmonary veins. It functions as the chamber that collects oxygen-rich blood before passing it to the left ventricle.
  • Right Ventricle: pumps deoxygenated blood into the pulmonary artery, directing it to the lungs for oxygenation. It plays a crucial role in pulmonary circulation.
  • Left Ventricle: pumps oxygenated blood into the aorta, distributing it throughout the body. It is the strongest chamber, responsible for systemic circulation.
