Trypsin - answer✔digests proteins into peptides. Acts on inactive processors to produce
chymotrypsin, carboxypeptidase and elastase
Secretin - answer✔Stimulates the flow of pancreatic juice rich in bicarbonate. inhibits secretion
of gastric juice, enhances effects of CCK and promotes normal growth of pancreas. Buffering ion
acid in chyme
Inhibin - answer✔Inhibits FSH secretion by anterior pituitary. Secreted by granulose cells of
growing follicles and the corpus lute after ovulation
Aldosterone - answer✔increases reabsorption of Na and water by the kidneys. this water
reabsorption increases total blood volume and increases blood pressure
Antidiuretic hormone (ADH) - answer✔is releases in response to dehydration or decreased blood
volume. Causes vasoconstriction which increases blood pressure.
Promotes movement of water from lumen of kidney tubules into the bloodstream
enhances water reabsorption by kidneys
Angiotensin II - answer✔Raises blood pressure by increasing systemic vascular resistance
potent vasoconstricter
stimulates secretion of aldosterone
Thrombin - answer✔converts soluble fibrinogen into insoluble fibrin which forms the threads of
the clot
Lingual Lipase - answer✔acts on as much as 30% of the dietary triglycerides and converts them
to simpler fatty acids and diglycerides.
Becomes activated in the acidic environment of the stomach thus starts working after food has
been swallowed
Salivary Amylase - answer✔A digestive enzyme that acts on starch
activated by chloride ions in saliva
breaks start down into maltose, maltatroise and a-dextrin
continues to break down food after it has been swallowed for about an hour
Basophil - answer✔release granules that contain heparin, histamine and serotonin which all
intensify inflammatory reactions and are involved in allergic reactions
similar function as mast cells
.5-1% of all WBC
Neutrophils - answer✔release several chemicals to destroy a pathogen
contain defensins which poke holes in microbe membranes
Participate in destruction of bacteria
Phagocytosis
60-70% of all WBC
Monocyte - answer✔Arrive in larger numbers and destroy more microbes. Once arriving they
enlarge and differentiate into wandering macrophages, which clean up cellular debris and
microbes by phagocytosis after an infection
3-8% of all WBC
Eosinophil - answer✔Believed to release enzymes such as histaminase that combat the effects of
histamine and other substances involved in inflammation during allergic reactions
phagocytize antigen-antibody complexes and are effective against parasitic worms
2-4% of all WBC
GnRH - answer✔stimulates gonadotrophs in the anterior pituitary to increase secretion of
luteinizing hormone (LH) and follicle stimulating hormone (FSH)
Controls the ovarian uterine cycles
Blastomere - answer✔the progressively smaller cells produced by cleavage
