Which blood vessels connect the two sides of the vascular system?.

Choice A rationale:

Abdominal thrusts, also known as the Heimlich maneuver, are a first-aid technique used to treat conscious choking victims in which the rescuer delivers thrusts to a patient’s upper abdominal region. This motion pushes air from the lungs up through the throat to dislodge foreign objects and treat upper airway obstructions.

Choice B rationale:

Chest thrusts can also be used if needed. However, they are not the primary method for dislodging a foreign object in someone that is choking.

Choice C rationale:

Chest pumps are not a recognized method for dislodging a foreign object in someone that is choking.

Choice D rationale:

Bowel thrusts are not a recognized method for dislodging a foreign object in someone that is choking.

So, the correct answer is Choice A.

The correct answer is Choice C. -

Choice A rationale:

The larynx is part of the airway but does not prevent aspiration. -

Choice B rationale:

The trachea is the airway leading to the lungs but does not prevent aspiration. -

Choice C rationale:

The epiglottis is a flap of tissue that covers the airway during swallowing, preventing food from entering the lungs. -

Choice D rationale:

The pharynx is part of the throat but does not prevent aspiration.

So, the correct answer is C, after analyzing all choices.
