TRANSCRIPT
HORMONES THAT AFFECT BLOOD SUGAR The Pancreas contains two
types of cells Produces digestive
enzymes Produces ______________–
located in structures called the islets of Langerhans
Over 2000 islets (each containing thousands of cells) are scattered throughout pancreas
Islets contain _________ and ______________cells which are responsible for the production of insulin and glucagon
REGULATION OF BLOOD SUGAR
blood sugar level(90mg/100ml)
insulin
body cells takeup sugar from blood
liver storesglycogen
reducesappetite
glucagon
liver releasesglucose
triggershunger
high
low

STORING AND RELEASING GLUCOSE!
Insulin released when blood sugar levels ________ insulin causes cells of muscles, liver, and
other organs to become _________________to glucose. Liver converts glucose to _____________________________
Insulin causes ____________________in blood sugar level
Glucagon causes _________________in blood sugar level (released when blood sugar levels are _____, promotes conversion of glycogen to ____________.
GREAT CANADIANS!
Dr. Charles ________ and Dr. Frederick _____________________
1923 Nobel Prize for the discovery of ________________(Best was excluded!!)
Did not profit from the discovery...unheard of today!
ADRENAL GLANDS
Located above each _______________________ Inner gland – adrenal _____________________
medulla surrounded by outer casing (adrenal cortex), regulated by the _____________________________________ hormones regulate the adrenal cortex
Adrenal medulla produces ___________hormones (produced when cells within adrenal medulla are stimulated by sympathetic nerves in times of __________________.__________________________________________________________
FIGHT OR FLIGHT!!
These two hormones initiate fight-or-flight biological responses
blood sugar level _______________________ glycogen converted to _____________________ ensures greater energy reserve available increase _______________and
__________________ rates as well as cell metabolism
blood vessels _____________________= allowing more oxygen and nutrients to reach tissues
irises ___________________________
ADRENAL CORTEX
Stimulated by _______________________________ Produces ___________different types of
hormones___________________________
one of the most important - ____________________, increases level of _______________________in blood and helps in recovery of stress by being converted to _________________ in liver, supplying more ______________________needed for repair or recovery by cells or participating in protein synthesis
____________________________ Salt and water balance – ALDOSTERONE!
____________________________ Small amounts!
LONG TERM STRESS RESPONSE hypothalamus sends hormone to
___________________lobe of pituitary stimulates pituitary to secrete corticotrophin
(adrenocorticotropic hormone; ___________) blood carries ACTH to target cells in ___________ cells of adrenal cortex secrete
mineralocorticoids and glucocorticoids (one of which is ____________)
these are carried to target cells in _____________ and _______________________
as cortisol levels rise, hypothalamus and pituitary production of _______________hormones ______________________
eventually cortisol levels begin to ____________
