  The primitive heart tube undergoes a ventrocaudal folding down and to the left to ultimately to lie in its final resting position.
- B.
  
  The right atrium consists of the right vitelline vein, primitive right atrium, and the sinus venarum.
- C.
  
  The majority of the heart is derived from surrounding mesenchyme of endodermal original.
- D.
  
  The flexible septum secundum functions as a primitive valve allowing for right to left shunting of blood in the fetus
- E.

2.

The following values are obtained: VO2 = 200 ml 02/min, Oxygen content within the pulmonary vein = 0.25ml 02/ml blood. Oxygen content within pulmonary artery is 0.20 ml 02/ml blood. Heart rate = 100 bpm. Amount of blood in the left ventricle immediately following the closure of the mitral valve was determined to be 100mL. What is this patient’s Ejection Fraction, and what would be the appropriate consultation? Ficks CO= HR x SV EF=SV/EDV
- A.
  
  Ejection fraction is approx 55% and is normal, they have nothing to worry about
- B.
  
  Ejection fraction is 40% indicating they may be experiencing some form of heart failure
- C.
  
  Ejection fraction is 65% indicating they are under the influence of some positive inotropic agents
- D.
  
  Ejection fraction is approx 40% and they have nothing to be concerned with, this is normal
- E.
  
  Ejection fraction is approximately 55%, and they should seek consultation
- F.
  
  Ejection fraction is 65% which is within the normal range
3.

Which of the following adequately characterizes eccentric hypertrophy?
- A.
  
  It is associated with the S4 heart sound
- B.
  
  It is due to a prolonged increase in afterload
- C.
  
  It is the result prolonged volume overload within the left ventricle
- D.
  
  It is the sound made in response to the rebounding of pressure in the left atrium
4.

- C.
  
  Small intestines to lymph to blood to adipose cells via ApoB48 and LPL interactions
- D.
  
  Small intestines to liver to blood to adipose cells via CII and LPL interactions.
- E.
