endocrine structure and function Flashcards
what is the function of the endocrine system?
Endocrine glands release hormones into the bloodstream. this lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth, and development, the way our organs work, metabolism, and reproduction.
what is the structure of the endocrine system?
many glands make up the endocrine system. The hypothalamus, pituitary gland, and pineal gland are in your brain. The thyroid and parathyroid glands are in your neck. The thymus is between your lungs, the adrenals are on top of your kidneys, and the pancreas is behind your stomach.
function of the hypothalamus?
The hypothalamus secretes hormones that stimulate or suppress the release of hormones in the pituitary gland, I addition to controlling water balance, sleep, temperature, appetite, and blood pressure.
function of the pituitary gland?
Through secretion of its hormones, the pituitary gland controls metabolism, growth, sexual maturation, reproduction, blood pressure, and many other vital functions and processes.
function of the pineal gland?
Receive information about the state of the light-dark cycle from the environment and covey this information by the production and secretion of the hormone melatonin.
function of the thyroid gland?
produces hormones that regulate the body’s metabolic rate, growth, and development. it plays a role in controlling heart, muscle and digestive function, brain development and bone maintenance.
function of the parathyroid.
to make the parathyroid hormone (PTH). This chemical regulates the amounts of calcium, phosphorus and magnesium in the bones and blood.
function of the thymus gland.
to train special white blood cells calledT-Lymphocytes or T-cells. White blood cells travel from your bone marrow to your thymus. the lymphocytes mature and become specialised T-cells in your thymus. After T-cells have matured, they enter your bloodstream.
function of the adrenal gland.
produce hormones that help regulate your metabolism, immune system, blood pressure, response to stress and other essential functions. Adrenal glands are composed of two parts, the cortex and the medulla, which are each responsible for producing different hormones.
function of the pancreas
it has 2 roles. it is an organ of the digestive system and of the endocrine system. The exocrine pancreas produces enzymes that help to digest food, particularly protein. The endocrine pancreas makes the hormone insulin, which helps to control blood sugar levels.
