Q

what are the glucocorticoids

A

cortisol and cortisone

35
Q

what does cortisol do

A

using gluconeogenesis (making glucose from lipids or proteins in the liver) increases blood glucose

36
Q

what do gonadocorticoids do

A

are androgens that are precursers to testosterone and estrogen. sex drive and armpit hair at puberty

37
Q

what is the pancreas’ exocrine function

A

relese bicarb into small intestine to make chyme less acidic and enzyme rich digestive juices for digestion

38
Q

endocrine function of the pancreas

A

hormones that regulate blood glucose levels

39
Q

what do pancreatic islets do

A

clusters of cells that serve endocrine function

40
Q

what cells are found in the pancreatic islets

A

alpha and beta cells

41
Q

what do pancreatic alpha

A

produce hormone glucagon

42
Q

what do beta cells do in pancreas

A

produce insulin

43
Q

what does glucagon do

A

liver catabolizes glucagon into glucose which is released into blood to increase glucose levels

44
Q

what does insulin do

A

insulin targets body cells to uptake glucose to decrease levels of glucose in blood

45
Q

what does estrogen do and what is it secreted by

A

by ovaries, sex organ development and body hair

46
Q

what does progesterone do

A

breast development and uterine cycles

47
Q

what does testosterone do and what is it secreted by

A

testes. development of sex organs, body hair, muscle mass and sex drive, sperm development

48
Q

what does the thymus do

A

lymphocyte maturity

49
Q

what does thymosin do and where is it secreted from

A

thymus. acts on T lymphocytes that are developing immunocompentence; chooses/trains T cell lineage

50
Q

which endocrine organ shrinks as we age and is replaced with connective tissue

A

thymus

51
Q

what secretes melatonin

A

pineal body/gland

52
Q

what does melatonin do

A

responsible for sleep/wake cycle. more released at night to promote sleeping and light inhibits melatonin
