Q

phospholipid made by alveolar type 2 cells that reduce surface tension in alveoli
essential for respiration
production does not begin until the end of the 6th month, making it difficult for premature babies born before 6 months to survive

Q

double layer of peritoneum that connects portions of the gut or other viscera to the body wall or to each other
provide pathways for nerves, blood vessels, and lymphatics to and from the viscera and help to support the organs in the abdomen

16
Q

organs suspended in the abdominal cavity by a mesentery

A

intraperitoneal

17
Q

posterior to the peritoneum

A

retroperitoneal

18
Q

space created posterior to the stomach by gut rotation
this space connects to the rest of the peritoneal cavity (greater peritoneal sac) through the epiploic foramen (of Winslow)

A

Omental bursa (lesser peritoneal sac)

19
Q

fold of peritoneum passing from the stomach to the liver (lesser) or from the stomach to the transverse colon and beyond (greater)

A

omentum

20
Q

opening between the lesser and greater sacs in the abdominal cavity located at the free margin of the lesser omentum between the duodenum and hte liver
in its ventral border lie the common bile duct, hepatic artery, and portal vein (the portal triad)

A

epiploic foramen (of Winslow)

21
Q

part of the ventral mesentery that attaches the liver to the ventral body wall

A

falciform ligament

22
Q

????

A

PORTAL TRIAD

23
Q

???

A

PRIMARY INTESTINAL LOOP

24
Q

connection b/w the yolk sac and the primary intestinal loop of the midgut through the connecting stalk
failure of this duct to degenerate results in fistulas and diverticula (Meckel’s diverticulum) from the small intestine to the umbilicus

A

vitelline duct

25
Q

???

A

PHYSIOLOGICAL UMBILICAL HERNIATION

Q

???

A

ANNULAR PANCREAS

27
Q

???

A

MOBILE CECUM

28
Q

???

A

VOLOVULUS

29
Q

ventral body wall defect caused by failure of physiologically herniated loops of bowel to return to the body cavity in the tenth week of development

A

Omphalocele

30
Q

ventral body wall defect
results from lack of closure of the laterl body wall folds in the abdominal region
results in protrusion of intestines and sometimes other organs through the defect

A

gastroschisis

31
Q

caused by the failure of the vitelline duct to degenerate

diverticulum from the small intestine to the umbilicus

A

Meckel’s diverticulum

32
Q

congenital absence of an opening or lumen

Ex: gut atresia

A

atresia (i.e. gut atresia)

33
Q

a narrowing of a canal or orfice

Ex: gut stenosis

A

stenosis (i.e. gut stenosis)

34
Q

wedge of mesoderm that grows down between the hindgut and primitive urogenital sinus–partially separates these two structures
caudal end of the septum forms the perineal body

A

urorectal septum

35
Q

???

A

URORECTAL FISTULA

36
Q

???

A

RECTOVAGINAL FISTULA
