Endocrine System Flashcards
Glycogen is converted into…?
Glucose due to glucagon
What is glucose stores as?
Glycogen via the secretion of insulin
Which region of the adrenal gland is responsible for producing aldosterone?
Cortex
Which region of the adrenal gland is responsible for producing adrenaline?
Medulla
Provide the function of glucagon:
Increases the level of sugar in the blood
Provide the function of insulin:
Reduces the level of sugar in the blood
Provide the function of oestrogen:
Repairs the endometrium
Make it more vascular
Provide the function of progesterone:
Makes the endometrium thicker and more vascular
Maintains the endometrium
Name the structure that produces progesterone
Corpus luteum
Name the structure that produces oestrogen
Graafian follicle
What hormone is produced by the testes?

What hormone keeps the smooth muscles of the uterus relaxed during pregnancy
Progesterone
Which hormone promotes cyclic changes in the endometrium?
Progesterone
What hormone produced by the ovaries is responsible for secondary sex characteristics?

Ovaries
Which hormone causes reabsorption of sodium ions?
Aldosterone
What hormone does the adrenal gland secrete?
Aldosterone and adrenaline
Adrenaline:
Fight or flight
Prepares body to deal with emergency
Function of adrenal gland (aldosterone):
Causes reabsorption of sodium ions
Vital for osmoregulation
Cortisol increases boys resistance to stress,also anti-inflammatory
Islets of Langerhans:
Alpha cells: glucagon (glucose increases)
Beta cells: insulin (glucose decreases) negative feedback affect on each other
Pancreas function:
Both endocrine and exocrine gland
Endocrine- islets of langerhans
Exocrine- pancreatic duct
What is the pancreas attached to?
Small intestine
Thyroid issues:
