Endocrine System

STUDY
PLAY
Endocrine system produces--- and fenestrated capillaries to allow direct transport into the bloodstream
Hormones
Produces Calcitonin in the thyroid gland
Parafollicular cells
Inactive thyroid hormone stored by follicular cells.
Colloid
prompted by TSH to modify T3 and T4
Colloid
Increase blood calcium and stimulates osteoclast to break down bond to alter vitamin D absorption
PTH
Produces Calcitonin in the parathyroid gland
Chief Cells
Does the Endocrine system have Ducts?
NO
produces Epinephrine and Norepinephrine in the medulla
Chromaffin
Produces aldosterone, minercorticoid in the cortex of adrenal gland
Zonula Glomerulosa
Produces Cortisol, glucocorticoids in the cortex of the adrenal gland
Zonula fasciculata
Produces adrenal gland in the cortex of adrenal gland
Zonula reticularis
3 zones of the cortex of the adrenal gland( outer to inner)
glomerulosa- fasciculata- reticularis
located in the sella turcica
pituary gland
middle and largest zone of the cortex in the adrenal gland
zonula fasciculata
Rathke's pouch is found here
Anterior Pituary
produces prolactin- breast milk
Mamotrophs in the anterior pituary
Produces growth hormone- involved in stress management, metabolism and growth
somatotrophs
2 acidophils
somatotrophs and mamotrophs
3 basophils
gonadotrophs, thyrotrophs, corticotrophs
produce FSH and LH
Gonadotrophs
Produces TSH
Thyrotrophs
Produces ACTH
Corticotrophs
support cells located in the pars nervosa( back portion of pituitary)
Pituicytes
Promotes water reabsorption by acting on the distal tubule and collecting duct
ADH
Controls contraction of smooth muscle in uterus and contributes to milk ejection
Oxytocin
fxn of urinary system
removes by products and urine from the body
Fxn of kidney
Eliminates drugs- excrete waste - maintains blood plasma volume- maintains extracellular volume- regulates blood pressure- Produces erythropoietin( RBC formation)
transports urine to the urinary bladder
ureter
Stores urine
urinary bladder
Functional unit of the kidney
Uniferous tubules
surrounded by bowman's capsule
renal corpuscle
visceral layer of bowman's capsule
podocytes
3 regions of henle's loop
descending, Henle's loop, and ascending
3 types of cells of the renal interstitium
fibroblasts, macrophages, and interstitial cells
3 regions of the distal tubule
pars recta, macula densa, and pars convulta
2 regions of the proximal tubule
proximal convoluted tubule and the pars recta of the proximal tubule
2 types of nephrons
Renal corpuscle and glomerulus
