1. What is the function of the pituitary gland?

• A. Regulating metabolism
• B. Producing bile
• C. Filtering blood
• D. Controlling muscle movement

Correct answer: A

Rationale: The pituitary gland, known as the 'master gland,' plays a crucial role in regulating various physiological processes by secreting hormones that control other endocrine glands. This includes the regulation of metabolism, growth, reproduction, stress response, and more. Therefore, the correct function of the pituitary gland is regulating metabolism, making choice A the correct answer. Choices B, C, and D are incorrect as the pituitary gland is not involved in producing bile, filtering blood, or controlling muscle movement.

2. Where would you be likely to find a Schwann cell?

• A. In the digestive system
• B. In the nervous system
• C. In the skeletal system
• D. In the muscular system

Correct answer: B

Rationale: Schwann cells are a type of neuroglia found in the peripheral nervous system. They are responsible for producing the myelin sheath around axons of neurons, which helps with the conduction of nerve impulses. Therefore, Schwann cells are typically found in the nervous system. Choices A, C, and D are incorrect because Schwann cells are specifically associated with the nervous system and are not found in the digestive, skeletal, or muscular systems.

3. Which system does the gall bladder belong to?

• A. endocrine system
• B. urinary system
• C. digestive system
• D. nervous system

Correct answer: C

Rationale: The gall bladder is part of the digestive system. Its primary function is to store and concentrate bile produced by the liver and release it into the small intestine to aid in the digestion of fats. This process facilitates the breakdown and absorption of fats from the food we consume. Choices A, B, and D are incorrect as the gall bladder is not associated with the endocrine, urinary, or nervous systems.

4. Which organ system is primarily responsible for generating antibodies?

• A. The endocrine system
• B. The digestive system
• C. The lymphatic system
• D. The nervous system

Correct answer: C

Rationale: The correct answer is C: The lymphatic system. Antibodies are produced by specialized white blood cells called B-lymphocytes (or B cells) in response to foreign substances known as antigens. The lymphatic system includes lymph nodes, lymphatic vessels, tonsils, thymus, and spleen, which work together to produce and store antibodies to help the body fight off infections and diseases. Choice A, the endocrine system, is incorrect because it is responsible for hormone regulation, not antibody production. Choice B, the digestive system, is incorrect because its main function is to break down food and absorb nutrients, not produce antibodies. Choice D, the nervous system, is incorrect as it is responsible for transmitting signals throughout the body and coordinating body functions, not generating antibodies.

5. What is the average normal body temperature in degrees Celsius?

• A. 30°C
• B. 32°C
• C. 35°C
• D. 37°C

Correct answer: D

Rationale: The average normal body temperature in degrees Celsius is 37°C. This temperature is considered the standard measurement for the human body under normal conditions. It is essential to know this baseline temperature for monitoring health and detecting abnormalities such as fever. Choice A, 30°C, is too low for the average normal body temperature. Choice B, 32°C, is also below the standard normal body temperature. Choice C, 35°C, is closer but still lower than the average normal body temperature of 37°C.
