4. What is the muscular sac in the female body that nourishes and protects a developing fetus?

• A. Ovary
• B. Fallopian tube
• C. Uterus
• D. Vagina

Correct answer: C

Rationale: The correct answer is C: Uterus. The uterus is a muscular sac in the female body where a fertilized egg implants and develops into a fetus during pregnancy. It provides nourishment to the developing fetus and protects it throughout gestation. The ovaries produce eggs, the fallopian tubes transport eggs from the ovaries to the uterus, and the vagina is the canal leading from the uterus to the outside of the body. Therefore, the uterus is the specific organ responsible for nourishing and protecting a developing fetus in the female body.

5. Which of the following is the main function of the pancreas?

• A. To store food and break it down into smaller pieces
• B. To absorb nutrients into the bloodstream
• C. To produce enzymes that help digest food
• D. To regulate blood sugar levels

Correct answer: C

Rationale: Rationale: The pancreas is a vital organ in the digestive system that produces digestive enzymes such as amylase, lipase, and proteases. These enzymes are released into the small intestine to help break down carbohydrates, fats, and proteins in food, aiding in the digestion and absorption of nutrients. Options A and B are incorrect because the pancreas is not involved in storing or absorbing nutrients. Option D is partially correct as the pancreas also plays a role in regulating blood sugar levels by producing insulin and glucagon, but its primary function is to produce digestive enzymes.
