1. In the human body, the ribs are ___________ to the lungs.

• A. medial
• B. superior
• C. anterior
• D. deep

Correct answer: C

Rationale: The correct answer is 'C: anterior.' The term 'anterior' refers to a position in front of or toward the front of the body. In this case, the ribs are positioned in front of the lungs when considering the anatomical position. The term 'medial' means toward the midline of the body, 'superior' means above or higher in position, and 'deep' refers to a position farther from the surface or external part. Therefore, the most appropriate choice is 'anterior' when describing the relationship between the ribs and the lungs.

2. What is the role of the gallbladder in digestion?

• A. To produce bile
• B. To store and concentrate bile
• C. To break down fats
• D. To secrete digestive enzymes

Correct answer: B

Rationale: The gallbladder's primary function in digestion is to store and concentrate bile produced by the liver. Bile is essential for the digestion and absorption of fats in the small intestine. While the gallbladder does not produce bile (Choice A) or secrete digestive enzymes (Choice D), it plays a crucial role in storing and releasing bile when needed. Therefore, the correct answer is B.

3. Which of the following locations is not involved in the release of hormones during stress?

• A. Parathyroid gland
• B. Adrenal cortex
• C. Posterior pituitary
• D. Hypothalamus

Correct answer: A

Rationale: The parathyroid gland is not involved in the release of hormones during stress. It is responsible for regulating calcium levels in the blood by secreting parathyroid hormone. During stress, the adrenal cortex, posterior pituitary, and hypothalamus play crucial roles in releasing stress hormones like cortisol, adrenaline, and oxytocin. Therefore, the correct answer is the parathyroid gland, as it is not directly associated with the release of stress-related hormones.

4. Where does primary peristalsis occur?

• A. Esophagus
• B. Stomach
• C. Nervous system
• D. Small intestine

Correct answer: A

Rationale: Primary peristalsis occurs in the esophagus. Peristalsis is the coordinated muscular contractions that propel food through the digestive tract. In the esophagus, primary peristalsis is the involuntary wave-like contractions that push food from the mouth to the stomach. It is the natural and automatic process that occurs to facilitate the movement of food during digestion. The stomach (choice B), nervous system (choice C), and small intestine (choice D) are not the primary sites where peristalsis occurs in the digestive system.

5. Which gland controls Calciferol?

• A. Thyroid
• B. Pituitary
• C. Parathyroid
• D. Hypothalamus

Correct answer: C

Rationale: Calciferol, commonly known as Vitamin D, is regulated by the parathyroid gland, not the thyroid, pituitary, or hypothalamus. The parathyroid gland plays a crucial role in maintaining calcium and phosphorus balance in the body by regulating the production of calcitriol, the active form of Vitamin D. This hormone helps in the absorption of calcium from the intestines and its reabsorption in the kidneys to maintain proper calcium levels in the blood. Therefore, the correct answer is the Parathyroid gland (Choice C). Choices A, B, and D are incorrect as they do not have a direct role in controlling Calciferol.
