1. What is the function of the large intestine in the digestive system?

• A. To secrete digestive enzymes
• B. To absorb water and form solid waste
• C. To produce bile
• D. To transport nutrients

Correct answer: B

Rationale: The large intestine's primary function is to absorb water from the remaining indigestible food matter that enters it from the small intestine. This absorption process helps in forming solid waste (feces) by compacting the material and preparing it for excretion. The large intestine does not secrete digestive enzymes, produce bile, or transport nutrients. Therefore, option B, 'To absorb water and form solid waste,' is the correct function of the large intestine in the digestive system.

2. Which hormone is not produced by the pituitary gland?

• A. FSH
• B. TRH
• C. LH
• D. ADH

Correct answer: B

Rationale: Thyrotropin-releasing hormone (TRH) is not produced by the pituitary gland. TRH is actually produced by the hypothalamus and acts on the pituitary gland to stimulate the release of thyroid-stimulating hormone (TSH). On the other hand, FSH (follicle-stimulating hormone), LH (luteinizing hormone), and ADH (antidiuretic hormone) are all hormones directly produced by the pituitary gland.

3. What is the name of the bone in the human thigh?

• A. Ulna
• B. Femur
• C. Radius
• D. Humerus

Correct answer: B

Rationale: The correct answer is B. Femur. The femur, also known as the thigh bone, is located in the human thigh. It is the longest and strongest bone in the human body, extending from the hip to the knee. The ulna, radius, and humerus, on the other hand, are bones found in the arm. Therefore, choices A, C, and D are incorrect as they are bones of the arm, not the thigh.

4. Which part of the brain is involved in processing visual information?

• A. Temporal lobe
• B. Occipital lobe
• C. Parietal lobe
• D. Frontal lobe

Correct answer: B

Rationale: The correct answer is B: Occipital lobe. The occipital lobe, situated at the back of the brain, is specifically responsible for processing visual information received from the eyes. It plays a crucial role in interpreting and making sense of visual stimuli, allowing individuals to perceive and comprehend the world around them. The Temporal lobe (Choice A) is involved in processing auditory information and memory, not visual processing. The Parietal lobe (Choice C) is responsible for processing sensory information from various parts of the body, but not specifically visual information. The Frontal lobe (Choice D) is involved in functions such as decision-making, problem-solving, and voluntary movement, but not processing visual stimuli.

5. What is the primary function of the skeletal system?

• A. To produce blood cells
• B. To protect organs
• C. To store fat
• D. To secrete hormones

Correct answer: B

Rationale: The primary function of the skeletal system is to protect vital organs, provide structural support, and enable movement. It serves as a framework that supports and protects internal organs, such as the brain, heart, and lungs. Choice A is incorrect because blood cell production primarily occurs in the bone marrow, a component of the skeletal system but not its primary function. Choice C is incorrect because fat storage is not a primary function of the skeletal system. Choice D is incorrect because hormone secretion is mainly regulated by endocrine glands, not the skeletal system.
