,1. Which organ system is primarily responsible for long-term
regulation and control of body processes?
A) Nervous System
B) Endocrine System
C) Digestive System
D) Integumentary System
Answer: B) Endocrine System
Rationale: The endocrine system regulates physiological
processes over extended periods through hormone
secretion.
2. What is the primary function of the myelin sheath?
A) To supply nutrients to neurons
B) To insulate the axon and increase signal speed
C) To provide structural support to the neuron
D) To connect neurons to one another
Answer: B) To insulate the axon and increase signal
speed
Rationale: Myelin sheaths facilitate rapid transmission of
electrical impulses along nerve fibers.
3. What cell type is most responsible for antibody
production?
A) T cells
B) Macrophages
C) B cells
D) Neutrophils
Answer: C) B cells
Rationale: B cells differentiate into plasma cells, which

, 4. Which of the following is NOT a function of the liver?
A) Bile production
B) Protein synthesis
C) Blood detoxification
D) Insulin production
Answer: D) Insulin production
Rationale: Insulin is produced by the pancreas, not the
liver.
5. Aldosterone primarily affects the reabsorption of which
ion in the kidneys?
A) Potassium
