1. What is the function of the pituitary gland?

• A. Produces hormones that regulate growth and metabolism
• B. Filters blood and removes waste products
• C. Stores and releases bile
• D. Produces red blood cells

Correct answer: A

Rationale: The pituitary gland is often referred to as the "master gland" because it controls the activity of many other endocrine glands in the body. It is located at the base of the brain and produces a variety of hormones that regulate various bodily functions, including growth, metabolism, reproduction, and blood pressure.

2. The final sentence suggests that users should approach social media with a healthy dose of

• A. Enthusiasm and optimism about its potential for connection and engagement.
• B. Skepticism and critical thinking towards the information encountered online.
• C. Acceptance of its flaws and a passive reliance on its features for interaction.
• D. Indifference towards its impacts and an absence of any effort to manage its use.

Correct answer: B

Rationale: The emphasis on "critical thinking" and "skepticism" suggests the importance of approaching social media with a cautious and discerning mind, aligning with B

3. Which of the following is NOT a function of the integumentary system?

• A. Regulation of body temperature
• B. Protection from pathogens
• C. Synthesis of vitamin D
• D. Production of digestive enzymes

Correct answer: D

Rationale: The correct answer is D: "Production of digestive enzymes." The integumentary system primarily consists of the skin, hair, nails, and glands. Its main functions include regulating body temperature through processes like sweating and shivering, protecting the body from pathogens and external threats, and synthesizing vitamin D when exposed to sunlight. However, the production of digestive enzymes is not a function of the integumentary system. Digestive enzymes are primarily produced by organs such as the pancreas and salivary glands to aid in the breakdown of food in the digestive system, which is separate from the functions of the integumentary system.

4. What is the scientific term for inflammation of the bronchi, often associated with a cough and mucus production?

• A. Pneumonia
• B. Bronchitis
• C. Emphysema
• D. Pleurisy

Correct answer: B

Rationale: The correct answer is B: Bronchitis. Bronchitis is the scientific term for inflammation of the bronchi, which are the air passages in the lungs. This condition is often characterized by a cough, mucus production, and difficulty breathing. Pneumonia (A) is an infection that causes inflammation in the air sacs in the lungs, not the bronchi. Emphysema (C) is a chronic lung condition that results in the damage of the air sacs in the lungs, leading to difficulty breathing. Pleurisy (D) is inflammation of the pleura, the lining around the lungs, and is not directly related to inflammation of the bronchi. Therefore, option B is the correct answer in this case.

5. Which of the following nutrients is essential for muscle growth and repair?

• A. Vitamin C
• B. Protein
• C. Carbohydrates
• D. Fat

Correct answer: B

Rationale: The correct answer is B: Protein. Protein is essential for muscle growth and repair because it provides the necessary building blocks called amino acids. These amino acids are crucial for repairing and building muscle tissue, which is essential for overall muscle growth and recovery. While vitamins like Vitamin C play a role in overall health and immune function, they are not directly involved in muscle growth and repair. Carbohydrates provide energy for workouts, but they are not the primary nutrient needed for muscle repair. Fat is important for overall health but is not as directly involved in muscle growth and repair as protein is.

6. What is the process by which the body reabsorbs water from the large intestine?

• A. Dehydration
• B. Osmosis
• C. Filtration
• D. Secretion

Correct answer: B

Rationale: Rationale: - Dehydration (Option A) refers to the condition of having insufficient water in the body, not the process of water reabsorption in the large intestine. - Osmosis (Option B) is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. In the large intestine, water is reabsorbed through osmosis to maintain the body's fluid balance. - Filtration (Option C) is a process where a liquid or gas passes through a filter to separate the components. It is not the primary mechanism for water reabsorption in the large intestine. - Secretion (Option D) is the release of substances from cells, but it is not the process by which the body reabsorbs water from the large intestine. Therefore, the correct process by which the body reabsorbs water from the large intestine is
