Multiple Choice

What do drowning and choking have in common in terms of their impact on the human body?

Both involve the obstruction of the airway, leading to a lack of oxygen.

Both are caused by the malfunction of the digestive system.

Both primarily affect the cardiovascular system.

Both result in the obstruction of blood flow to the brain.

Verified step by step guidance

Begin by identifying the primary systems involved in drowning and choking. Both conditions primarily affect the respiratory system, as they involve the airway.

Understand the mechanism of obstruction in both cases. Drowning involves water entering the airway, while choking involves a foreign object blocking the airway.

Recognize the consequence of airway obstruction. In both drowning and choking, the obstruction prevents oxygen from reaching the lungs, leading to hypoxia (lack of oxygen).

Consider the physiological impact of hypoxia. The lack of oxygen affects the entire body, but the brain is particularly sensitive to oxygen deprivation, which can lead to unconsciousness or brain damage.

Conclude that both drowning and choking share the commonality of airway obstruction, leading to a lack of oxygen, which is critical for survival and affects the body's ability to function properly.
