between peritoneal layers

Question 6

peritoneal sac

Answer 6

all visceral and parietal membranes

Question 7

peritoneal cavity

Answer 7

a potential space within peritoneal sac ; contains small amount of serous fluid ; allows organs to move freely without friction

clinical significance of peritoneal cavity

Answer 8

potential space but can become an actual space ; can contain several liters of fluid (ascites) caused by prolonged disease, injury, infection

Question 9

ascites

Answer 9

pooling of blood caused by disease, injury, infection (blood, bile, feces) causes peritoneal cavity to go from a potential space -> actual space
