QUESTIONS WITH 100% CORRECT ANSWERS 2025
What is a hormone? - correct answer-
Secreted by endocrine glands into internal environment to help regulate metabolic processes.
What do hormones control? - correct answer-
Rates of certain chemical reactions, aid in transporting substances through membranes, and help regulat
e water balance, electrolyte balance, and blood pressure.
Hormones play a role in what? - correct answer-Reproduction, development, and growth
How do hormones deliver messages to cells? - correct answer-
They unite with binding site of the receptor.
What is the role of negative feedback in control of hormone secretions? - correct answer-
They are controlled by negative feedback
How does negative feedback work with hormone secretion? - correct answer-
A stimulus elicits the release of substance, once the substance reaches a certain level, it sends a signal
that stops further release of the substance.
What does negative feedback do for the bloodstream? - correct answer-
Regulates the hormone levels present
Paracrine secretions enter what? - correct answer-Interstitial fluid.
What do paracrine secretions effect? - correct answer-Only nearby cells
What is an example of a paracrine secretion? - correct answer-
release of histamine from certain white blood cells causing dilation of nearby blood cells.
What do autocrine secretions affect? - correct answer-only the cell secreting the substance
,What is an example of an autocrine secretion? - correct answer-
liver cells stimulating themselves to release stored iron
What do endocrine glands secrete? - correct answer-chemical substances and hormones
Where do endocrine glands secrete substances? - correct answer-Into the internal environment
Exocrine glands secrete chemical substances that enter what? - correct answer-
Tubes or ducts that lead to body surfaces
What is an example of an exocrine gland? - correct answer-sweat released from skin
What are the different endocrine glands in the body? - correct answer-
Pituitary gland, thyroid gland, parathyroid gland, adrenal gland, pancreas, pineal gland, thymus, reprod
uctive glands, liver, heart, kidneys, and gastrointestinal tract.
Where is the pituitary gland located? - correct answer-The base of the brain
