  1. size and location of the heart?
    size: 14 centimeters long and 9 centimeters wide

    location: within the mediastinum and rests on the diaphragm
  2. covering of the heart:

    a. a layered _____ encloses the heart
    b. the pericardial cavity is a space between the _____ and  _______ layers of the pericardium
    • a. pericardium
    • b. parietal; visceral
  3. three walls of the heart.
    1. epicardium, myocardium and an endocardium
  4. right chambers and valves. Name the sequence of blood flow.
    • -right atrium receives blood from the vena cavae
    • -tricuspid valve separates the right atrium and the right ventricle
    • -pulmonary valve guards the base of the pulmonary trunk. leads blood into the lungs.
  5. left chambers and valves.
    • -left atrium receives blood from the pulmonary veins.
    • -bicuspid valve separates the left atrium from the left ventricle. 
    • -aortic valve guards the base of the arota.
  6. skeleton of the heart: what does it consist of?
    fibrous rings that enclose the bases of the pulmonary artery and the aorta.
  7. cause of heart sounds?
    vibrations the valve movements produce.
  8. arteries do what?
    carry blood away from the heart.
  9. what happens in the capillaries?
    blood and tissue fluid exchange gases and nutrients.
  10. what do veins do?
    carry blood to the heart.
  11. how are veins formed
    venules continue from the capillaries and merge to form veins
  12. systolic pressure.
    ventricle contracts
  13. diastolic pressure
    ventricles relax
  14. what's the largest artery?
  15. major branches of the aorta (and know where)
    coronay, brachiocephalic, left common coratid and left subclavian arteries
  16. artery branches descending the aorta include
    thoracic and abdominal
  17. arteries to the neck, head and brain
