Objectives
  • .
  • Fetal Heart
  • Heart physiology
  • Heart coloring
  • There are two types of teachers the kind that
    fill you with so much quail shot that you cant
    move, and the kind that just gives you a little
    prod from behind and you jump to the skies.

Fetal Heart
  • Foramen ovale
  • hole between the right and left atrium
  • Ductus arteriosus
  • blood vessel between the pulmonary trunk and
    aorta
  • Both of the above close when the first breath is
    taken
  • change of pressure

4
Cardiac Muscle
  • Can beat on its own
  • If two fibers touch, they beat together
  • Intercalated discs
  • Allow for electrical transfer to other cells.

5
Heart Physiology
  • Each beat is stimulated by an area in the right
    atrium near the superior vena cava called the
    Sinoatrial Node (SA Node).
  • SA Node is innervated by the autonomic nervous
    system
  • Pacemaker of the heart
  • Stimulates both atria to contract

6
Heart Physiology
  • SA Node sends impulse to the AV
    (atrioventricular) Node.
  • Located in the interatrial septum
  • Holds impulse for a short time (milliseconds) and
    passes electrical impulse to AV Bundle (Bundles
    of His)
  • AV Bundles passes impulse to Purkinje fibers
    which stimulates the ventricles to contract

Blood flow
  • Deoxygenated blood enters the heart from the
    inferior vena cava, superior vena cava, and the
    coronary sinus
  • From rt atrium to rt ventricle through the
    tricuspid valve
  • From rt ventricle to pulmonary trunk through the
    pulmonary semilunar valve

12
Blood flow
  • From the pulmonary trunk to the rt and left
    pulmonary arteries to the lungs
  • Oxygenated blood returns from the lungs in the
    pulmonary veins to the left atrium
  • From the left atrium to the left ventricle
    through the bicuspid valve

13
Blood flow
  • From the left ventricle to the aorta through the
    aortic semilunar valve
  • From the aorta to the rest of the body
  • Back to the right atrium through the inferior
    vena cava, superior vena cava, and coronary sinus
