Q

What are the sacculations in the colon called?

A

Haustra

17
Q

What is a watershed area?

A

An area that receives dual blood supply from the most distal branches of two large arteries.. Essentially sparing them from ischemia if one goes down. However, in a systemic hypoperfusion, these regions are susceptible to ischemia due to the fact that they are supplied by the most distal arterial branches and are least likely to receive sufficient blood!

18
Q

Where is pain initially referred in appendicitis?

A

Umbilicus (T10).

19
Q

What does rebound tenderness at McBurney’s point indicate?

A

Inflammation is no longer limited to the bowel and it has extended to the parietal peritoneum.

20
Q

What is a portal system?

A

Arrangement of vasculature in which blood must pass through 2 sets of capillaries between the L ventricle and the R atrium

21
Q

What are the two sets of capillaries in the hepatic portal system?

A
  1. Gut wall

2. Liver

22
Q

What is the large lymph node at the junction of the aorta and celiac trunk?

A

Cisterna Chyli

23
Q

Which of the following vessels would need to be clamped to control bleeding from a perforating duodenal ulcer?

  1. Proper hepatic
  2. Splenic
  3. Gastroduodenal
  4. IVC
  5. R Gastric
A
  1. Gastroduodenal
24
Q

A small specimen from a portion of the GI tract was taken for pathological examination. The specimen revealed abundant circular folds. Which organ is the likely source of the speciment?

A

Jejunum

25
Q

Which of the following is not a site of portal-caval anastomoses?

  1. inferior esophageal vein/L gastric vein
  2. Middle colic vein/L colic vein
  3. paraumbilical vein/inferior epigastric vein
  4. superior rectal vein/inferior rectal vein
A
  1. Middle colic vein/L colic vein
26
Q

Which of the following organ/blood supply relationships is correct?

  1. appendic/inferior mesenteric a.
  2. Hepatic flexure/celiac trunk
  3. Liver/Celiac Trunk
  4. Pancreas/inferior mesenteric artery
  5. Spleen/superior mesenteric a.
A
  1. Liver/Celiac Trunk
