Endocrine System Flashcards
one of the two important control systems of the body. It is composed of glands and cells that secrete the chemical signals called hormones into the bloodstream.
ENDOCRINE SYSTEM
The hormones are secreted in response to humoral, neural,or hormonal stimuli and then travel into the bloodstream (plasma of the blood) to target cells, where they regulate ______?
homeostasis
what are 10 the Major Functions of The Endocrine System
Regulation of metabolism, Control food intake and digestion, Modulation of tissue development, Regulation of ion levels, Control water balance, Changes in heart rate and blood pressure, Control of blood glucose and other nutrients, Control reproductive functions, Stimulation of uterine contractions and milk release and Modulation of immune system function
a function of End. Sys. that controls the rate of nutrient utilization and energy production
Regulation of metabolism
a function of End. Sys. that Regulates the level of satiation (fullness) and the breakdown of food into individual nutrients.
Control food intake and digestion
a function of End. Sys. that Influences the development of tissues, such as those of the nervous system.
Modulation of tissue development
a function of End. Sys. that Helps monitor blood pH, as well as Na+, K+, and Ca2+ concentrations in the blood.
Regulation of ion levels
a function of End. Sys. that Regulates water balance by controlling the solute concentration of the blood.
Control water balance
a function of End. Sys. that Helps regulate the heart rate and blood pressure and prepare the body for physical activities.
Changes in heart rate and blood pressure
a function of End. Sys. that Regulates the levels of glucose and other nutrients in the blood.
Control of blood glucose and other nutrients
a function of End. Sys. that Controls the development and functions of the reproductive systems in male and female.
Control reproductive functions
a function of End. Sys. that Regulates uterine contractions during delivery (or menstruation) and stimulates milk release from the breasts in lactating females.
Stimulation of uterine contractions and milk release
a function of End. Sys. that Helps control the production of immune cells
Modulation of immune system function
what are the 10 Glands of the Endocrine System
Hypothalamus, Pituitary Gland, Pineal Gland, Thyroid, Parathyroid, Thymus, Ovaries, Testes, Pancreas and Adrenal Gland
Maintains the body’s homeostasis and regulates body temperature, heart rate, and blood pressure
Hypothalamus
Composed of 2 lobes; the anterior, which secretes hormones involved in body’s growth and development, and the posterior, which secretes hormones that increase the reabsorption of water into the kidneys.
Pituitary Gland
The pituitary gland is composed of 2 lobes, what are these?
anterior and posterior
Responsible for the production of melatonin, which plays a major role in the body’s sleep-wake cycle.
Pineal Gland
Butterfly-shaped gland that produces 3 major hormones: calcitonin (helps regulate calcium levels in the blood), triiodothyronine (T3; control of metabolism), and thyroxine (T4; responsible for your metabolism, mood, and body temperature). They help regulate the body’s energy and metabolism
Thyroid
thyroid gland produces 3 major hormones, what are these?
calcitonin, triiodothyronine, thyroxine
helps regulate calcium levels in the blood
calcitonin
T3; control of metabolism
triiodothyronine
