Anatomy

1. Which of the following is NOT a function of the integumentary system?

Correct answer: D

Rationale: The correct answer is D: "Production of digestive enzymes." The integumentary system primarily consists of the skin, hair, nails, and glands. Its main functions include regulating body temperature through processes like sweating and shivering, protecting the body from pathogens and external threats, and synthesizing vitamin D when exposed to sunlight. However, the production of digestive enzymes is not a function of the integumentary system. Digestive enzymes are primarily produced by organs such as the pancreas and salivary glands to aid in the breakdown of food in the digestive system, which is separate from the functions of the integumentary system.

2. Which of the following structures is responsible for preventing the backflow of blood from the left ventricle into the left atrium?

Correct answer: D

Rationale: The correct answer is D, the mitral valve. The mitral valve, also known as the bicuspid valve, is located between the left atrium and the left ventricle. Its main function is to prevent the backflow of blood from the left ventricle into the left atrium during ventricular contraction. The aortic valve (A) is responsible for preventing the backflow of blood from the aorta into the left ventricle, the pulmonary valve (B) prevents backflow from the pulmonary artery into the right ventricle, and the tricuspid valve (C) prevents backflow from the right ventricle into the right atrium. Therefore, the mitral valve is specifically responsible for preventing backflow in the left side of the heart, making it the correct answer in this case.

3. Which part of the brain is responsible for regulating heart rate, breathing, and swallowing?

Correct answer: C

Rationale: The correct answer is C: Medulla oblongata. The medulla oblongata is located at the base of the brainstem and is responsible for regulating essential functions such as heart rate, breathing, and swallowing. It contains vital control centers for these automatic processes, making it a critical part of the brain for maintaining life. The cerebrum is primarily involved in higher brain functions such as thinking and voluntary movement, while the cerebellum helps with coordination and balance. The thalamus acts as a relay station for sensory information. Therefore, the medulla oblongata is the most appropriate choice for regulating these basic physiological functions.

4. What is the primary difference between science and pseudoscience?

Correct answer: B

Rationale: Both science and pseudoscience can explore similar topics, but their methods and reliance on evidence differentiate them.

5. What happens to the momentum of an object when there is no external force acting upon it?

Correct answer: c

Rationale: In the absence of external forces, momentum remains constant due to the conservation of momentum.

6. What is the unit of measurement for power?

Correct answer: c

Rationale: Power is measured in watts (W) in the SI unit system.
