ENDO VIVA Flashcards
What glands are in the endocrine system
Hypothalamus
Pituitary gland
Pineal gland
Thyroid gland
Parathyroid gland
Adrenal gland
Pancreas
Ovaries
Testes
The hypothalamus and pituitary gland
Located in the brain
Work as a unit to regulate all other endocrine glands and the release of hormones for the entire system
The pituitary gland
Splits into a anterior and posterior which react with the hypothalamus differently
The anterior pituitary gland
Has a capillary network with the hypothalamus and this is where FLAT PEG hormones are released
The posterior pituitary gland
Releases ADH and oxytocin from the hypothalamus by a nerve stimulation
The pineal gland
Located in the brain
Releases melatonin and acts as the bodies internal clock by processing information about the environment
The thyroid gland
Located in the neck
Produces thyroxin to regulate metabolism and energy levels
The parathyroid gland
Regulates calcium levels in the blood and secretes the parathyroid hormone when calcium levels are low
The adrenal glands
Located on the top of the kidneys
Have a cortex on the outside and a medulla on the inside
The cortex produces corticosteroids such as cortisol and aldosterone
The medulla produces adrenaline and noradrenaline to determine the bodies stress response
The pancreas
Located in the Epigastric Region of the abdomen
Releasing insulin and glucagon to determine and alter the bodies blood glucose levels
Pancreas is part of both the endocrine and exocrine hormone release
The sex hormones
Female= ovaries releasing oestrogen
Males= testes releasing testosterone
The functions of the endocrine system
A collection of glands over the body with no physical connection
They work to maintain homeostasis of the internal environment
Glands are surrounded by a network of capillaries to diffuse the produced hormones into the bloodstream using negative feedback loops
A negative feedback loop
Where cell growth and metabolism is influenced
How stability and homeostasis is maintained in the body
If there is too much of a hormone in the body, glands will send signals to the hypothalamus and pituitary receptors to stop creating and releasing these hormones
Endocrine glands
Have no ducts so secretions are released directly into the blood to be carried
Exocrine glands
Chemicals produced by exocrine glands are carried away in a duct as a chemical secretion
