Endocrine System Flashcards
Body Systems Review
homeostasis
regulation of an organism’s internal environment to maintain conditions needed for life.
endocrine gland
hormone-producing gland that
releases its product into the bloodstream.
hormone
substance, such as estrogen, that is produced by an endocrine gland and acts on target cells.
pituitary gland
endocrine gland located at the base of the brain; called the “master gland” because it regulates many body functions.
calcitonin
thyroid hormone involved in regulation of blood calcium levels.
parathyroid hormone
substance produced by the parathyroid gland that increases blood calcium levels by
stimulating bones to release calcium.
insulin
hormone produced by the pancreas that works
with glucagon to maintain the level of sugar in the blood.
glucagon
hormone produced by the pancreas that signals liver cells to convert glycogen to glucose and release glucose into the blood.
aldosterone
steroid hormone produced by the adrenal cortex that acts on the kidneys and is important for sodium reabsorption.
cortisol
a glucocorticoid that raises blood glucose levels, reduces inflammation, and is produced by the adrenal cortex.
antidiuretic hormone
functions in homeostasis by regulating water balance.
endocrine structures
glands and hormones
endocrine functions
- regulates and controls
growth, development
and metabolic activity - maintain homeostasis
using negative
feedback
what does endocrine system produce, and what are they (specific or nonspecific,)
hormones, which are lock and key and specific, distributed to the bloodstream and body cells
negative feedback loop
When a change occurs in the body there is a response
in the opposite direction that brings the system back to
homeostasis. ex body temperature
