1. Which of the following are considered normal values for the measure of a person’s pulse and blood pressure?

Correct answer: B

Rationale: Normal values for pulse rate typically range between 60 to 100 beats per minute, while normal blood pressure values are usually around 120/80 mm Hg. Option B falls within these normal ranges for both pulse rate and blood pressure, making it the correct choice. Choices A, C, and D have either pulse rate, blood pressure, or both values outside the normal ranges, making them incorrect.

2. Which of the following epithelial types is correctly matched with its major function?

Correct answer: D

Rationale: The correct answer is D. Simple columnar epithelium is indeed primarily responsible for secretion and absorption due to its tall shape and presence of microvilli, which increase surface area for these functions. Simple squamous epithelium is mainly involved in diffusion, allowing for the exchange of gases or nutrients. Stratified squamous epithelium functions more for protection against mechanical stress and pathogens, as it forms a tough, protective barrier due to its many layers.

3. What substance makes up the pads that provide support between the vertebrae?

Correct answer: B

Rationale: Cartilage is the correct answer as it is the substance that makes up the pads between the vertebrae. Cartilage provides cushioning and support between the bones of the spine, allowing for flexibility and preventing friction between the vertebrae. Bone (choice A) is incorrect as it forms the structure of the vertebrae, not the intervertebral discs. Tendon (choice C) is incorrect as it connects muscle to bone and is not found between the vertebrae. Fat (choice D) is incorrect as it is not the substance that makes up the pads between the vertebrae.

4. What is the function of the liver in the digestive system?

Correct answer: B

Rationale: The correct answer is B: To produce bile. The liver's primary function in the digestive system is to produce bile. Bile is essential for the digestion and absorption of fats in the small intestine. It helps emulsify fats, making it easier for enzymes to break them down into smaller molecules for absorption. Choices A, C, and D are incorrect as storing glucose is primarily done in the liver for energy maintenance, detoxifying harmful substances is a function of the liver related to metabolism but not specifically in the digestive system, and absorbing nutrients is mainly done in the small intestine rather than the liver.

5. Which type of blood vessel carries blood back to the heart?

Correct answer: C

Rationale: Veins are the blood vessels that carry deoxygenated blood back to the heart, except for the pulmonary veins which carry oxygenated blood from the lungs. Arteries carry oxygenated blood away from the heart. Capillaries facilitate the exchange of nutrients and gases between the blood and tissues but do not specifically carry blood back to the heart. Lymphatic vessels are part of the lymphatic system responsible for immune function and do not directly carry blood back to the heart. Therefore, the correct answer is veins.
