  • Circulatory system moves blood throughout the body to help tissues get enough oxygen and nutrients, and it helps them get rid of waste
    products (carbon dioxide).
  • Oxygenated blood - It refers to the blood rich in oxygen. O2
    concentration is high and CO2 is low, Lungs > Heart > Body cells (Tissues)
  • Deoxygenated blood - It refers to the blood rich in carbon dioxide.
  • Arteries transport blood away from the heart.
  • Aorta is the largest artery.
  • Veins return blood back toward the heart.
  • Superior and inferior vena cava are the largest vein.
  • Capillaries surround body cells to deliver and absorb O2 nutrients, and other substances. The site of gas exchange.
  • The superior vena cava carries blood from the head, neck, arms, and chest to the right atrium.
  • The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle via tricuspid valve.
  • The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis to the right atrium.
  • The pulmonary veins transport oxygen-rich blood back to the heart from the lungs.
  • The left ventricle (LV) pumps oxygen-rich blood through the aorta to be distributed to the entire body.
  • External respiration, also known as breathing, involves both: bringing O2 into the lungs (inhalation) and releasing CO2 to the atmosphere (exhalation).
  • Internal respiration is the exchange of gases between the bloodstream (blood vessels) and the cell.
  • Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart.
  • Systemic circulation moves blood between the heart and the rest of the body.
  • Superior & Inferior Vena Cava - Right Atrium - Tricuspid Valve - Right Ventricle - Pulmonary Valve - Pulmonary Artery - Pulmonary Vein - Left Atrium - Mitral Valve - Left Ventricle - Aortic Valve - Aorta
  • Nervous Control - Most animals have some type of nervous system with distinct organization
    of neurons
