3. Which vitamin requires intrinsic factor from the stomach for proper absorption?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin B12

Correct answer: D

Rationale: The correct answer is D, Vitamin B12. Vitamin B12 requires intrinsic factor, a glycoprotein produced by the parietal cells in the stomach, for proper absorption in the small intestine. Intrinsic factor binds to B12 and facilitates its absorption in the ileum. Without intrinsic factor, the body cannot effectively absorb Vitamin B12, leading to deficiencies and various health issues. Vitamins A, C, and D do not require intrinsic factor for absorption and have different mechanisms for uptake and utilization within the body.

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

• A. Osteoporosis

A dislocation (D) occurs when the bones in a joint are forced out of their normal position, but it is not the term for a broken bone.
