  • What are the three types of Red Blood Cells and their functions?
    RBC's carry oxygen and carbon dioxide. WBC's fight infections. Platelets allow the blood to clot in wounds.
  • Which human blood type is known as "the universal donor"? Explain why.
    Type O blood is the "Universal Donor" because the red blood cells have no antigens for WBC's to attack.
  • What are the differences between atria and ventricles?
    Atria receive blood, act as reservoirs, then drain the blood to ventricles which then pump the blood out to the lungs and body.
  • Name 7 things that get transported in the blood of the human circulatory system.
    Oxygen, Carbon Dioxide, Water, Nutrients, Hormones, Immune System Components, and Cellular Wastes

  • A person's blood type is determined by the presence or absence of certain molecules known as __________.
    Antigens
  • How are arteries and veins different?
    Typically! Arteries carry oxygen rich blood away from the heart and Veins deliver blood back to the heart.
  • What cellular organelle is most responsible for putting carbon dioxide into the bloodstream?
    the Mitochondria
  • When blood vessels ___________ less blood flows through them. When blood vessels _________ more blood flows through them
