Section 1: Foundations of the Endocrine System
--- --- --- --- --- --- ---
1. What is the overall function of the endocrine system?
--- --- --- --- --- --- --- --- --- ---
• A. To control voluntary muscle movement
--- --- --- --- --- ---
• B. To filter waste from the blood
--- --- --- --- --- --- ---
• C. To provide structural support for the body
--- --- --- --- --- --- --- ---
• D. A major regulatory system that uses hormones to produce
--- --- --- --- --- --- --- --- --- -
-- homeostatic adjustments --- ---
Answer: D --- ---
Rationale: The endocrine system is a major regulatory system of
--- --- --- --- --- --- --- --- --- ---
the body that uses chemical messengers (hormones) to produce
--- --- --- --- --- --- --- --- ---
,homeostatic adjustments as well as other functions like growth
--- --- --- --- --- --- --- --- ---
and reproduction . It does not control voluntary muscle movement
--- --- --- --- --- --- --- --- --- ---
(nervous system), filter blood (renal system), or provide structural
--- --- --- --- --- --- --- --- ---
support (skeletal system).

2. What makes the endocrine glands function as a coordinated
--- --- --- --- --- --- --- --- --- ---
"system"? ---
• A. They are all physically connected by ducts
--- --- --- --- --- --- --- ---
• B. They are all controlled directly by the heart
--- --- --- --- --- --- --- --- ---
• C. They all secrete hormones that interact functionally to
--- --- --- --- --- --- --- --- ---
regulate body processes --- --- ---
• D. They are only active during the daytime
--- --- --- --- --- --- --- ---
Answer: C --- ---
Rationale: Although they are separate anatomical structures,
--- --- --- --- --- --- ---
endocrine glands function as a system because they release
--- --- --- --- --- --- --- --- ---
hormones that work together to regulate various body
--- --- --- --- --- --- --- ---
,processes . They are not physically connected, not controlled by
--- --- --- --- --- --- --- --- --- ---
the heart, and are active continuously.

3. How is the endocrine system different from other physiological
--- --- --- --- --- --- --- --- --- --
- systems? ---
• A. It has glands dispersed throughout the body
--- --- --- --- --- --- --- ---
• B. It is controlled by the nervous system
--- --- --- --- --- --- --- ---
• C. It only functions during sleep
--- --- --- --- --- ---
• D. It uses electrical signals
--- --- --- --- ---
Answer: A --- ---
Rationale: The endocrine system differs from other physiological
--- --- --- --- --- --- --- ---
systems because it has glands dispersed throughout the body
--- --- --- --- --- --- --- --- ---
that are not connected structurally but form a coordinated system
--- --- --- --- --- --- --- --- --- -
-- through hormonal signaling . The nervous system uses electrical
--- --- --- --- --- --- --- --- ---
signals, and the endocrine system is not limited to sleep periods.

4. Which of the following is NOT a component of the
--- --- --- --- --- --- --- --- --- --- ---
endocrine system? --- ---
• A. Pituitary gland
--- --- ---
• B. Thyroid gland
--- --- ---
• C. Adrenal glands
--- --- ---
• D. Sweat glands
--- --- ---
Answer: D --- ---
Rationale: Sweat glands are exocrine glands (they secrete
--- --- --- --- --- --- --- ---
through ducts), not endocrine glands (which secrete directly into
--- --- --- --- --- --- --- --- ---
the bloodstream) . The pituitary, thyroid, and adrenal glands are
--- --- --- --- --- --- --- --- --- -
-- all components of the endocrine system.

5. Define a "Hormone" in physiological terms.
--- --- --- --- --- ---
• A. An electrical impulse sent through a nerve cell
--- --- --- --- --- --- --- --- ---
• B. A digestive enzyme released into the stomach
--- --- --- --- --- --- --- ---
