Q

Renin

A

from Kidney

Function: cleaves angiotensinogen to form angiotensin I

25
Q

Erythropoietin (EPO)

A

from Kidney

function: stimulates red blood cell production in bone manrrow

26
Q

Calcitriol

A

From Kidney

Function: Increases body calcium ( is the active form of vitamin D)

27
Q

Angiotensinogen

A

From: Liver
Function: converted in blood to angiotensin II, which stimulates aldosterone secretion, promotes thirst, and causes vasoconstriction and secretion of vasopressin.

28
Q

From Liver

Function: promote cell division and growth of many tissues. (Also secreted by other tissues like muscle)

29
Q

Insulin

A

From Pancreas

Function: promote uptake and storage of nutrients by most cells

30
Q

Glucagon

A

From Pancreas

Function: Maintains blood levels of nutrients after a meal and during stress.

31
Q

Parathyroid hormone

A

From: parathyroid gland
Function: Increase Ca2+ and decrease plasma phosphate levels in the blood by action on kidney and bone; stimulates vitamin D activation by action at kidney bone and intestine.

32
Q

Melatonin

A

From Pineal Gland
Function: Controls circadian rhythms; seasonal breeding, migration, hibernation, causes skin lightening in amphibians and lampreys

33
Q

Vasopressins )ADH)

A

From : Posterior pituitary gland

function: Regulates water re-absorption at kidney; vasoconstriction.

34
Q

Oxytocin

A

Posterior Pituitary

Function: Stimulates uterine contraction during parturition and milk ejection from mammary glands during suckling

35
Q
