  2. Right atrium
  3. pulmonary circuit pump
  4. Function of Ventricles
  5. coronary circulation
  1. a the functional blood supply of the heart, is the shortest circulation in the body.
  2. b
    1 of 4 chambers; smooth, thin, posterior wall; thin, rough anterior wall; receives superior and inferior venae cavae and coronary sinus
  3. c returns blood from body regions inferior to the diaphragm. (lack oxygen.
  4. d the right side of the heart. short, low-pressure circulation.
  5. e to pump blood from the heart.

5 Multiple choice questions

  1. 4 veins: enter the left atrium; transport blood from the lungs back to the heart (best seen posteriorly)
  2. tough, dense connective tissue layer protects the heart, anchors it to surrounding structures, and prevents overfilling of the heart with blood.
  3. increase the atrial volume somewhat.
  4. collects blood draining from the myocardium
  5. The endocardium underlies the much more voluminous myocardium, the muscular tissue responsible for the contraction of the heart.
    Cardiac muscle is a type of involuntary striated muscle found in the walls and histologic foundation of the heart, specifically the myocardium.

5 True/False questions

  1. Right ventricleincrease the atrial volume somewhat.

          

  2. interatrial septumthe internal partition that divides the heart longitudinally at the atria

          

  3. systemic circuit pumpleft side of the heart. takes a long pathway through the entire body and encounters about five times as much friction or resistance to blood flow than the pulmonary circuit pump.

          

  4. Where is the endocardium found and what kind of tissue is it?The endocardium underlies the much more voluminous myocardium, the muscular tissue responsible for the contraction of the heart.
    Cardiac muscle is a type of involuntary striated muscle found in the walls and histologic foundation of the heart, specifically the myocardium.

          

  5. Anterior interventricular sulcusalso known clinically as the left anterior descending artery: follows the anterior interventricular sulcus and supplies blood to the interventricular septum and anterior walls of both ventricles;
