1. Which of the following is NOT a function of the endocrine system?

Correct answer: D

Rationale: The endocrine system is responsible for producing hormones that regulate various bodily functions such as growth, metabolism, mood, and more. Facilitating digestion through muscle contractions is primarily the role of the muscular and nervous systems, not the endocrine system. Therefore, option D is the correct answer as it does not align with the functions typically attributed to the endocrine system. Choices A, B, and C are functions that are indeed associated with the endocrine system, making them incorrect answers in the context of this question.

2. What type of tissue is found in the outermost layer of skin?

Correct answer: C

Rationale: The correct answer is C: Epithelial tissue. Epithelial tissue forms the outermost layer of the skin, providing protection against external factors. It serves as a barrier and helps in preventing water loss and entry of pathogens into the body. Choice A, Muscle tissue, is incorrect as muscle tissue is responsible for movement, not skin structure. Choice B, Connective tissue, is incorrect as it provides support and structure to the body but is not the main component of the outermost layer of the skin. Choice D, Nervous tissue, is incorrect as nervous tissue is responsible for transmitting signals within the body, not for the outermost layer of the skin.

3. Which organ in the body is responsible for maintaining electrolyte balance and filtering waste from the blood?

Correct answer: B

Rationale: The correct answer is B: Kidneys. The kidneys are responsible for filtering waste from the blood and maintaining electrolyte balance. They help regulate the body's fluid levels and produce urine as a means of waste elimination. The liver primarily plays a role in detoxification and metabolism, not in maintaining electrolyte balance or filtering waste from the blood. The heart is responsible for pumping blood, not for electrolyte balance or waste filtration. The lungs are primarily involved in gas exchange, not in maintaining electrolyte balance or filtering waste from the blood.

4. What is the main function of the lungs?

Correct answer: D

Rationale: The main function of the lungs is to exchange oxygen and carbon dioxide between the body and the environment. This process occurs through the alveoli in the lungs where oxygen from inhaled air enters the bloodstream, and carbon dioxide is removed from the bloodstream and exhaled. Option A is incorrect as the transportation of oxygen and nutrients throughout the body is primarily carried out by the circulatory system, not the lungs. Option B is incorrect as coordinating movement and sensory information is a function of the nervous system, not the lungs. Option C is incorrect as filtering waste products from the blood is primarily the role of the kidneys, not the lungs. Therefore, the correct answer is D.

5. What is the scientific term for a broken bone?

Correct answer: B

Rationale: The scientific term for a broken bone is a fracture. Osteoporosis is a condition characterized by weak and brittle bones, not a broken bone. A sprain involves an injury to a ligament, not a bone. Dislocation occurs when the ends of bones are forced out of their normal positions at a joint, which is different from a fracture.
