Front 1

thyroid

Back 1

secrets thyroxine the bodys major meatboic hormone stimulates energy production in cells

Front 2

iodine

Back 2

improtant component of thyoxine

Front 3

thyroid alos scretes calcitonin which helps maintain normal calcium

Back 3

levels in the blood it stumulates the bone building c ells to absorb the excess calcuum and the dinetys to absorb and excrete exvess calcium

Front 4

parathyroid gland

Back 4

assist in regu of clacium parathyroid hormone when calcium levels are low telling bone dissolving cells to break down bone and release calcium into bloodstream and reduces the amount calcium in the urine

Front 5

adrenal glands

Back 5

two parts
outer part called the adrenal cortex
inner part called adrenal medulla

adrenal cortex produces hormones called corticosteroids which regulate the bodys meabolism its balance of salt and water and the immmune system and sexual function
adrenal medulla produces hormones called catecholamines epi and norepi which assist the body in coping with physical and emotional stress by incressing the heart resp rates and bp

Front 6

hypothalmus

Back 6

during times of stress secretes a hormone that stimulates the anterior pituitary to release adrenocorticotropic hormone it targets the adrenal cortex an causes it to secert cortisol a glucocorticoid stimulates most body cells to increase their energy production

Front 7

hypothalmus

Back 7

stimulates flight or fight responce thru the adrenal medulla secretes small amounts of norepi and large amounts of epinephrine

Front 8

norepi

Back 8

raises bp causing blood vessesl and skeltal muscle to constict

Front 9

epi

Back 9

stimulates sympathetic nervous sywstem receptors throughtout the body in addiction it stimulates the liver to convert glycogen to glucose

Front 10

pancreas

Back 10

digestive gland thatis considered both an ednocrine gland and exocrine gland exocrine componet is responsible for the secretion of the digestive enzymes the endocrine comprises th islets of langerhans these cell groups within the pancreas act like an organ with in an organ the main hormone s they secerte glucagon and insulin which are responsible for the reg of bgl

Front 11

glucagon

Back 11

is secreted in the system thru blood stream glucagon stimulate the liver to change glycogen into sugar and secrete it into the bloodstream where cells use it for energy
