Question 1 of 5
Which of the following structures can serve as a passageway for both food and air?
Correct Answer: B
Rationale: The correct answer is the Laryngopharynx. It is a common passageway for both food and air. The Esophagus (

Question 2 of 5
Which structure in the skin is responsible for producing oil that keeps the skin and hair moisturized?
Correct Answer: B
Rationale: The correct answer is B: Sebaceous gland. Sebaceous glands are responsible for producing oil (sebum) that keeps the skin and hair moisturized. Sudoriferous glands produce sweat, not oil, and are involved in temperature regulation. Hair follicles are responsible for hair growth and do not produce oil directly. Melanocytes are cells responsible for producing melanin, the pigment that gives skin its color, and are not involved in oil production.
Question 3 of 5
Which part of the digestive system is responsible for absorbing water and forming feces?
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.
