The pancreas functions as both an endocrine and exocrine gland. Which of the following accurately describes its dual role?
A. The exocrine function involves hormone release, while the endocrine function involves the secretion of buffers and enzymes.
The exocrine function involves hormone release, while the endocrine function involves the secretion of buffers and enzymes.: this reverses the roles; exocrine does enzymes/buffers, endocrine does hormones.
B. The endocrine function involves the secretion of digestive enzymes, while the exocrine function involves hormone release.
The endocrine function involves the secretion of digestive enzymes, while the exocrine function involves hormone release.: reversed roles.
C. The exocrine function involves the release of insulin and glucagon, while the endocrine function involves hormone release.
The exocrine function involves the release of insulin and glucagon, while the endocrine function involves hormone release.: insulin and glucagon are endocrine products, not exocrine.
D. The endocrine function involves the release of insulin and glucagon, while the exocrine function involves the secretion of digestive enzymes and buffers.
The endocrine function involves the release of insulin and glucagon, while the exocrine function involves the secretion of digestive enzymes and buffers.: the pancreas’ islet cells secrete insulin/glucagon (endocrine) and acinar/bicarbonate secretions go to the duodenum (exocrine).

Which male reproductive gland is responsible for secreting a milky fluid that nourishes and protects sperm and helps neutralize the acidic environment of the female reproductive tract?
A. Bulbourethral gland
Bulbourethral gland: Bulbourethral (Cowper’s) glands produce a clear mucous pre-ejaculate that lubricates the urethra and can neutralize small amounts of urine but do not produce the milky, nutrient-rich fluid described.
B. Skene's gland
Skene's gland: Skene’s glands are female periurethral glands (not male) and are not involved in semen production.
C. Bartholin's gland
Bartholin's gland: Bartholin’s glands are female vestibular glands producing lubrication during arousal -not involved in male semen.
D. Prostate gland
Prostate gland: The prostate secretes a slightly alkaline, milky fluid that nourishes/protects sperm and helps neutralize the acidic vaginal environment .

Carbon dioxide is transported through the blood by 3 mechanisms. What are those 3 mechanisms? (Select all that apply)
A. Converted to carbon monoxide
Converted to carbon monoxide: CO (carbon monoxide) is a different gas and is not a product or transport form of CO₂.
B. Bind to myoglobin
Bind to myoglobin: Myoglobin primarily binds O₂ within muscle cells; CO₂ transport by myoglobin is not a main mechanism.
C. Binds to hemoglobin
Binds to hemoglobin: CO₂ can bind to hemoglobin (forming carbaminohemoglobin) as one transport form.
D. Converted to bicarbonate ions
Converted to bicarbonate ions: Most CO₂ is converted to bicarbonate (HCO₃⁻) in red blood cells and transported in plasma.
E. Dissolved in plasma
Dissolved in plasma: A small proportion of CO₂ is carried dissolved directly in plasma.

What is the maximum volume of air that can be expelled from the lungs after maximum inspiration?
A. Expiratory reserve volume
Expiratory reserve volume: Expiratory reserve volume is the additional air that can be forcefully exhaled after a normal exhalation, not the maximum after a maximal inhalation.
B. Inspiratory capacity
Inspiratory capacity: Inspiratory capacity is the maximum amount of air that can be inhaled after a normal exhalation (tidal volume + inspiratory reserve), not the total that can be expelled after maximum inspiration.
C. Vital capacity
Vital capacity: Vital capacity is the maximum volume of air that can be expelled from the lungs after a maximum inspiration (inspiratory reserve + tidal + expiratory reserve) .
D. Tidal volume
Tidal volume: Tidal volume is the volume of a normal, resting breath and is far less than the maximum expelled volume.
