1. Which organ of the body compensates when a person's intake of vitamins decreases?

• A. Appendix
• B. Liver
• C. Pancreas
• D. Stomach

Correct answer: B

Rationale: The liver is the organ that compensates when a person's intake of vitamins decreases. It stores certain vitamins, such as vitamins A, D, E, K, and B12, and releases them when dietary intake decreases. This helps maintain the body's vitamin levels and functions. The other organs listed - Appendix, Pancreas, and Stomach - do not primarily play a role in compensating for a decrease in vitamin intake. The liver is crucial in maintaining vitamin balance, making it the correct choice in this context.

2. What is the main function of the large intestine?

• A. To absorb proteins
• B. To absorb water and form feces
• C. To produce enzymes for digestion
• D. To store fat

Correct answer: B

Rationale: The main function of the large intestine is to absorb water and form feces from waste material. Choice A is incorrect because the absorption of proteins primarily occurs in the small intestine. Choice C is incorrect as the production of enzymes for digestion mainly takes place in the pancreas and small intestine. Choice D is incorrect as the storage of fat is not a primary function of the large intestine.

3. What are the white blood cells responsible for coordinating the immune response called?

• A. Red blood cells
• B. Platelets
• C. Lymphocytes
• D. Neutrophils

Correct answer: C

Rationale: Lymphocytes, which include B cells, T cells, and natural killer cells, are responsible for coordinating the immune response. They play a crucial role in recognizing and fighting against pathogens and foreign substances in the body. Red blood cells are responsible for oxygen transport, platelets aid in blood clotting, and neutrophils are white blood cells primarily involved in combating infections. Therefore, the correct answer is C, lymphocytes, as they are specifically involved in coordinating immune responses.

4. Which term refers to the act of inhaling foreign objects into the airway?

• A. Expiration
• B. Respiration
• C. Aspiration
• D. Inhalation

Correct answer: C

Rationale: Among the options provided, aspiration is the term that specifically refers to the act of inhaling foreign objects into the airway. Expiration refers to breathing out, respiration is the overall process of gas exchange in the body, and inhalation is the act of breathing in air or other substances into the lungs. Therefore, the correct answer is C, aspiration. It is crucial to understand these terms in the context of airway management and respiratory care to ensure proper identification and treatment of related conditions.

5. Which part of the digestive system is responsible for absorbing water and forming feces?

• A. Stomach
• B. Small intestine
• C. Large intestine
• D. Esophagus

Correct answer: C

Rationale: The correct answer is the large intestine. The large intestine is responsible for absorbing water and forming feces from undigested food. The stomach's main function is to break down food with acid and enzymes. The small intestine is where most of the nutrients are absorbed into the bloodstream. The esophagus is the tube that connects the mouth to the stomach and does not play a role in absorbing water or forming feces.
