1

serum glucose maintained by insulin and glucagon ratio

homeostasis

2

endocirine system is linked with

nervous system and immune system

3

exocrine secretes

onto the surface usually though a duct

4

endocrine secretes

hormones into the blood stream

5

chemical substance synthesized & secreted by a specific organ or tissue

hormones

6

what penetrates the cell membrane and interact with intracellular receptors

steroid and thyroid hormones (lipid-solube)

7

what binds to receptors located on the surface of cell membranes

protein hormones

8

activated by imbalance, the action of a hormone results in changes that negate the inital stimulus for its secretion

Negative feedback system

9

what is an example negative feedback

increase in insulin = increase in glucose
decrease in Ca = increase PTH

10

increase target action beyond normal

positive feedback, example oxytocin

11

what involves hormones among several glands to turn off and on target organ hormone secretion

complex feedback

12

what is an exampe of intrinsic rhythmic secretion of hormones

circadian rhythm

13

ultradian

greater than 24 hour cycle
menstral cycle

14

stress can cause your blood glucose to

elevate

15

integrated chemical, communication and coordination system that enables what

growth, development, reproduction and regulation of energy

16

a chronic multisystem diseas related to abnormal insulin production, imparied insulin utilization or both

diabetes mellitus

17

normal insulin is produced by what

the B cells in the islets of langherans of the pancreas

18

what is the normal glucose range

70-120 mg/dl

19

type 1 diabetics are

prior to age 30, need insulin for life bc they no longer can produce insulin

20

type 2 diabetics are

after age 35, change with diet, excercise and insulin

21

alpha cells secrete

glucagon

22

beta cells secrete

insulin

23

glucagon & insulin play a vital role in the metabolism of

carbs, proteins and fats

24

the primary endocrine function of pancreas is to

regulate blood glucose

25

in a healthy body normal blood glucose level is maintained by

insulin and glucagon ratio

26

insulin is the _____ to unlock cell membrane for glucose to enter

the key

27

what cant enter cell without insulin

glucose

28

insulin unlocks the door to allow

glucose to enter the cell

29

without insuin the body enter serious state of what

breaking down of body fat and protein

30

increase urine, caused by osmotic diuresis caused by excesive glucose in urine

polyuria
