CHAMBERS AND ASSOCIATED GREAT VESSELS

• 4 Chambers of the Heart:

  • Atria (right and left) - receiving chambers
  • Ventricles (right and left) - discharging chambers
• Interatrial septum - separates the 2 atria

  Interventricular septum - separates the 2 ventricules
• Arteries - carry blood away from the heart

  Veins - carry blood toward the heart
• Pulmonary circulation - blood flows from the right side of the heart to the lungs and back to the left side of the heart
• Systemic circulation - oxygen-rich blood returned to the left side of the heart is pumped out into the aorta; oxygen-poor blood return to the right atrium via systemic veins
