1. What is the function of the small intestine?

• A. To store bile
• B. To absorb nutrients
• C. To digest food
• D. To produce enzymes

Correct answer: B

Rationale: The small intestine is the primary site for nutrient absorption in the digestive system. It is responsible for absorbing nutrients from the digested food into the bloodstream for distribution throughout the body. Therefore, the correct function of the small intestine is to absorb nutrients. Choice A is incorrect because the gallbladder stores bile, not the small intestine. Choice C is incorrect because the digestion process primarily occurs in the stomach and small intestine. Choice D is incorrect because while the small intestine does play a role in enzyme production, its primary function is nutrient absorption.

2. Which cut is considered a cross section?

• A. A sagittal or frontal section
• B. A cut along the coronal plane
• C. A cut along the median plane
• D. A cut through the transverse plane

Correct answer: D

Rationale: The correct answer is D: A cut through the transverse plane. A transverse plane cut, also known as a cross-section, divides the body or an organ into superior and inferior portions. This type of cut is perpendicular to the long axis of the body and is commonly used in medical imaging to display internal structures and organs in a horizontal view. Choices A, B, and C are incorrect because a sagittal or frontal section (A) divides the body into left and right portions, a cut along the coronal plane (B) separates the body into anterior and posterior parts, and a cut along the median plane (C) divides the body into equal left and right halves.

3. What structures are likely torn in a rotator cuff tear?

• A. Tendon and possibly ligament
• B. Muscle and possibly tendon
• C. Ligament and possibly muscle
• D. Tendon only

Correct answer: A

Rationale: In a rotator cuff tear, the most common structures torn are the tendons of the rotator cuff muscles. In severe cases, the tear may also extend to involve the surrounding ligaments. Therefore, the correct answer is A, as it accurately represents the structures that are likely to be affected in a rotator cuff tear. Choice B is incorrect as muscles are not typically torn in a rotator cuff tear. Choice C is also incorrect as ligaments are not the primary structures involved in a rotator cuff tear. Choice D is incorrect because a rotator cuff tear typically involves more than just the tendons.

4. Which of the following is not part of the central nervous system?

• A. Retina
• B. Spinal cord
• C. Brain
• D. Heart

Correct answer: B

Rationale: The central nervous system consists of the brain and spinal cord, which are responsible for processing and coordinating information. The retina is part of the eye, while the heart is part of the circulatory system. Therefore, the correct answer is 'Spinal cord' as it is not part of the central nervous system.

5. What is the main function of the urinary bladder?

• A. To filter blood
• B. To store and concentrate bile
• C. To store urine
• D. To absorb nutrients

Correct answer: C

Rationale: The correct answer is C: To store urine. The main function of the urinary bladder is to store urine produced by the kidneys before it is excreted from the body. It acts as a reservoir for urine until it is expelled during urination. Choices A, B, and D are incorrect because the urinary bladder does not filter blood, store or concentrate bile, or absorb nutrients. It is solely responsible for storing and releasing urine.
