metabolsim

Answer 2

production of cellular energy or ATP

constructive/degradative cellular activities

Question 3

visceral peritonium

Answer 3

immediately surrounds organs

Question 4

parietal peritonium

Answer 4

lines body wall

Question 5

peritonial cavity

Answer 5

between 2 membranes

filled with serous fluid

allowed limited movement of organs within cavity

Question 6

mesentery

Answer 6

sheet of 2 serous membranes fused back to back

provide route for blood/nerve/lymph vessels to reach visceral organs

most common

hold organs in place

Answer 8

fat over the stomach

in ventral mesentery

Question 9

Answer 9

organs attached to mesenteries

Question 10

adhere to dorsal peritoneal wall + loose mesenteries

ex. pancreas, parts of colon, kidneys

Question 11

peritonitis

Answer 11

inflammation of peritoneal membrane

Question 12

causes of peritonitis

Answer 12

piercing abdominal wound

perforating ulcer that leaks stomach juices into cavity

burst appendix that leaks bacteria w/ feces into peritonium

Question 13

effects of peritonitis

Answer 13

gives time to macrophages to attack pathogens, prevent spread of infection

widespread is lethal

Question 14

treatments for peritonitis

Answer 14

removing debris from infected area

heavy antibiotic doses

Question 15

blood circulation: splanchnic circulation

Answer 15

includes branches of abdominal aorta + hepatic portal circulation

celiac trunk

Answer 17

5 branches

4. branches of R. gastric

Answer 21

to gallbladder

Question 22

5. branches of L gastric

Answer 22

to esophagus

Question 23

hepatic portal circulation

Answer 23

drain digestive organs, spleen, pancreas + deliver to liver through hepatic portal

Question 24

liver is drained by

Answer 24

two hepatic veins that enter inferior cava

Question 25

liver + hepatic portal circulation

Answer 25

blood contains large amts of nutrients after eating
