(Endocrine/Exocrine) gland produces non hormonal substances such as sweat and saliva.
(Endocrine/Exocrine) gland releases hormones into the surrounding tissue fluid.
(Endocrine/Exocrine) gland release secretions into a duct that leads out onto a surface.
(Endocrine/Exocrine) gland contains a rich vascular system so that secretions can be received.
An increase in concentration of glucose in the blood stimulates the pancreas to secrete insulin is an example of
(negative/positive) feedback.
The onset of contractions during childbirth causes the release of oxytocin which stimulates further contractions of the
uterus is an example of (negative/positive) feedback.
Thyroxine levels are low causing the pituitary gland to release thyroid stimulating hormone, which stimulates the thyroid to
release more thyroxine is an example of (negative/positive) feedback.
Water concentration in the blood stream is low causing the release of antidiuretic hormone which causes the body to hold
water and not release it as urine is an example of (negative/positive) feedback.
Suckling stimulates the release of oxytocin which causes milk letdown from mammary glands, which stimulates more
suckling, causing the release of more oxytocin resulting in increased milk letdown is an example of (negative/positive)
feedback.
The (endocrine/nervous) system regulates the activity of muscles and glands via electrochemical impulses delivered by
neurons that provide (immediate/long term) response to changes. The (endocrine/nervous) system influences homeostasis
by releasing hormones that provide (immediate/long term) response to changes.
(Amino acid/Steroid) based hormones cannot diffuse through the plasma membrane and as a result require a secondary
