Chapter 32 Flashcards
What is the endochrine system?
hormones produced in one location that effects somewhere else in the body, they can exist for seconds,days, years, it is a slow change that is determined by response receptors.
what is the nervous system?
signals generated in single/multiple locations & can act locally/elsewhere, signals last a min/sec and can be produced at a high rate, with a fast channel, and it can be specifically determined by connections and/ receptor response.
what is the endochrine pathway?
stimulus—->endochrine cell—->hormone—-> effector cell—-> RESPONSE
what is the neuroendochrine to neueroendochrine pathway
stimulus—> sensory cell—->neurotransmitter—-> central nervous system—->neurohormone——>endochrine cell—->hormone—-> effector cell—>RESPONSE
are all endochrine glands endochrine glands?
(secrete into blood) digestive glands are exochrine glands (secrete into ducts)
thyroid/parathroid:
metabolic process
adrenal:
fight/flight
pineal:
biological rhythms
hypothalamus:
control of posterier pituitary
posterior pituitary:
reproductive—> kidney
anterior pitutitary
reproductive, adrenal functional, growth
pancreas:
digestion, glucose, metabolism
gonads
testies, ovaries, secondary sex characters/reproductive
what is the theme of kidneys?
pump everything into one location and extract what you want
malpighiantubes?
hemolymphh (water, nutrients, and nitrogenous waste)
why is burned in the hindgut to absorb electrolytes?
ATP
what stays in the hindgut to excrete?
nitrogenous waste
potassium pump draws water/ nutrients in —–>
malpihian—–> digestive tract—-> filters
how is water and electrolytes balanced in terrestrial vertebrates
through the renal passage: kidney
what is comprised in the kidney?
renal cortex (outer layer), renal medulla (deeper inner tissue), renal artery, renal vein (both for blood flow)
what does the nephron do
does all the work
what is also included in the kidney?
nepron (does all the work), pistal tubule, proximal tubule (reabsorpbtion of what they want)bowmans capsule (entire group of filter cells), glomerous (network of filter cells), loo of henle (keep drawing water out of the urine), renal corpusle (where it starts), vesa recta
