hormonal condition Flashcards
what is the endocrine system
glands that send horomes to the organ whe=ic has receptors that pick it up and trigger a response
examples of hormones
insulin for blood sugars
adreneline for fight or flight
hormones are produced by the endocrine gland and control chemicals
dif between hormones and nervous system
horones are slower to effect but are much longer lasting
whats the pituary gland
the main gland that controls all the others
sends hormones to other glands telling them what hormones to release
its hormones;
send FSH that stimulates the ovarues makes females oestrogen and eggs
makes sperm and terstosterone
stimulates thyroid gland to make thyroxine through TSH- tells other glands what to do
what does tyroid gland do
releases thyroxine as instructed by the pituary gland and controls the rate of metabolism
what does the pancreas do
controls glucose levels
adrenal role
prepares for stress (tp make adrenaline)
what do ovaries do
controls developemtn of women sexual characteritis and menstural cycle
what do testes do
produce sperm and developement of men secondary sex characteristsos
how does pancreas do its function
it controls the glucose levels in the blood
a hormone called insulin controls the storage of glygcogen in liver when the blood glucose in blood is high
and a hormone called glucagon stimulates the release of glycogen stored glucose molecules back into the blood stream
what happens if theres too much glucose
if thers too much to store as glycogen it will turn into lipids, if you consume more and more you will become obesese
what does glucagon do
when theres not enough glucose the pancreas uses it tk tell the liver to break down glucose ti be put back into the blood.
it can also break down amino acids and fats for more glucose
what happens if you have type one diabetes
the pancreas doesnt make enough insullin hormone so the blood glucose levels can get too high
glucose goes out in urine if this happens so you piss a lot and it cant get into cells so you lose energy so you can to use lipids hence weight loss
what happens if you have type 2 diabetes
if you eat too much the ancreas cant make enough for your bodies weight so you lack energy and the cells stop responding to insullin
how to treat type 1 diabetes
you have to inject insulin before meals so it can combat the glucose you will digest
when excersising you have to be careful to keep blood glucose levels steady so enough glucose can be used to respire
ways they hope to cure diabetes
a pancreas implant is rare and not very successful but has been tried a lot
scientists are trying to make stem cells produce insulin, turn ones that make enzymes into insulin
they alsp hope to enjineers faulty pancreas cells to work
probs the easiest is to use embryo stem cells specially created to make insulin
