Lab 14: The Digestive System Flashcards
why is gut activity not important in fight or flight
situation needs to increase skeletal muscle activity, thus increase HR and contraction strength to pump more O2 to muscles
= gut does not need to be active
= decrease muscle activity of gut, more blood flow to skeletal muscle
where is pancreatic lipase produced
PANCREAS
where is pepsinogen produced
stomach mucosa (chief cells)
where is trypsinogen produced
pancreas
where is bile produced
liver
where does lipid digestion occur
SI
will salivary amylase have any effect on table sugar
no, only acts on polysaccharide (starch)
= thus, does not break down polysaccharide glycogen b /c cannot attack branching leakages
= thus, cant digest cellulose b/c enzymes lacking
appendicitis meaning
painful and swelling of appendix
= becomes inflamed and infected
gallstones meaning
hardened deposits of bile that can form in gallbladder (crystalline bodies)
heartburn meaning
pain & burning in upper/ middle part of stomach & chest; =symptom of acid reflex disease
= excess acids backs up from stomach and esophagus
Crohns disease
inflammatory bowel disease
tissues are inflamed and have deep sores usually in last part of SI
=may be abnormal response to normal intestine bacteria by immune system
how does epinephrine affect cardiac muscle (strength and rate) and smooth muscle
cardiac (increase strength & contraction)
smooth muscle (decrease strength & increase contraction)
how does acetylcholine affect cardiac muscle (strength and rate) and smooth muscle
cardiac (decrease strength & rate)
smooth muscle (increase strength and rate)
epinephrine or acetylcholine
which chemical is released by sympathethic ns
epinephrine
epinephrine or acetylcholine
which chemical is released by parasympathethic ns
acetylcholine
