1. Which of the following structures is responsible for the production of
cerebrospinal fluid (CSF)?
A) Cerebrum
B) Thalamus
C) Choroid plexus
D) Medulla oblongata
Answer: C) Choroid plexus
Rationale: The choroid plexus is responsible for the production of
cerebrospinal fluid (CSF) in the brain. It is located in the ventricles and
helps maintain the environment of the central nervous system (CNS).
2. What is the primary function of the alveoli in the lungs?
A) Filtration of air
B) Production of surfactant
C) Exchange of oxygen and carbon dioxide
D) Regulation of blood pressure
Answer: C) Exchange of oxygen and carbon dioxide
Rationale: The alveoli are the tiny air sacs in the lungs where gas
exchange occurs. Oxygen from the air diffuses into the blood, and
carbon dioxide diffuses from the blood into the alveoli to be exhaled.
3. Which part of the brain is primarily responsible for regulating heart
rate and breathing?
A) Cerebellum
B) Medulla oblongata
,C) Hippocampus
D) Corpus callosum
Answer: B) Medulla oblongata
Rationale: The medulla oblongata, located in the brainstem, is crucial
for controlling vital autonomic functions such as heart rate, breathing,
and blood pressure.
4. Which of the following is a primary function of the kidneys?
A) Secretion of hormones
B) Filtration of blood to form urine
C) Production of digestive enzymes
D) Regulation of body temperature
Answer: B) Filtration of blood to form urine
Rationale: The kidneys are responsible for filtering waste from the
blood to form urine, helping to regulate electrolyte balance, fluid
volume, and waste elimination.
5. Which of the following is an example of a long bone?
A) Phalanges
B) Sternum
C) Scapula
D) Patella
Answer: A) Phalanges
Rationale: The phalanges are long bones, located in the fingers and
toes. They are characterized by having a long shaft and two expanded
ends.
, 6. Which of the following hormones is released by the pancreas to lower
blood glucose levels?
A) Insulin
B) Glucagon
C) Cortisol
D) Epinephrine
Answer: A) Insulin
Rationale: Insulin is a hormone produced by the pancreas that helps
regulate blood glucose levels by promoting the uptake of glucose into
cells, thus lowering blood glucose.
7. Which of the following is the most abundant type of white blood cell
in the human body?
A) Basophils
B) Neutrophils
C) Lymphocytes
D) Eosinophils
Answer: B) Neutrophils
Rationale: Neutrophils are the most abundant type of white blood cells
in the human body and are key players in the body's immune response,
particularly in fighting bacterial infections.
