endocrine sys functions
maintain homeostasis. Adjust nutrient levels Respond to the environment Direct growth and development Endocrine system organs function by: Sending signals to other organs. Receiving signals from other organs. Changing their behavior based on the signals. Signals are sent from one organ to another via the bloodstream.
hypothalamus
structure in your brain that makes and releases many hormones
sends hormones into the blood that travel directly to the anterior pituitary gland
Hormones from the
anterior pituitary gland
stimulate other
endocrine glands.
Aden/o
gland
Adren/o, adrenal/o
adrenal gland located on top of kidney like party hat
Cortic/o
outre surface referring to adrenal cortex
Gonad/o
sex organs, testes and ovaries
Pancreat/o
pancreas
Pituitar/o, hypophsy/o
pituitary gland
Thym/o
thymus
Thyr/o, thyroid/o
thyroid
Gluc/o, glucos/o,
glyc/o
sugar
Crin/o
secretion, to secrete
pituitary gland
secretes hormones
into the blood that act on other organs
Adrenocorticotropic hormone (ACTH)
Stimulates the outer part of the adrenal gland, pit gland
Thyroid-stimulating hormone (TSH)
Thyroid secretes T3, T4, and
calcitonin, pit gland
Luteinizing hormone (LH) and folliclestimulating hormone (FSH)
Stimulate the gonads, pit gland
Thyroid gland
T3 and T4
Hyperthyroidism
Hypothyroidism
Calcitonin

Pancreas
Endocrine function is to secrete hormones Insulin – decreases blood sugar Glucagon – increases blood sugar
Adrenal gland
Adrenal gland Medulla Epinephrine (adrenaline) Cortex Corticosteroids • Mineralocorticoids: mineral balance • Glucocorticoids- sugar balance • Testosterone and estrogen
Hormone levels are
detected by
measuring blood
concentration levels
of nutrients.
Common
measurements:
- Hyperglycemia: high blood sugar
- Hypoglycemia: low blood sugar
- Euglycemia: good blood sugar
Can also measure
endocrine function
by
urinalysis
•Glucosuria: sugar in urine- sign of diabetes
•Ketonuria: ketones in the urine- faulty carb digestion
Hormon/o
hormone
