Each lobule of a lung has a bronchiole serving many [1] that are surrounded by blood capillaries where gas exchange occurs.

Which structure is the site of gas exchange between inhaled air and the bloodstream?Multiple choice question.alveolusprimary bronchustrachealobar bronchus

The human gas-exchanging organ, the lung, is located in the thorax, where its delicate tissues are protected by the bony and muscular thoracic cage. The lung provides the tissues of the human body with a continuous flow of oxygen and clears the blood of the gaseous waste product, carbon dioxide. Atmospheric air is pumped in and out regularly through a system of pipes, called conducting airways, which join the gas-exchange region with the outside of the body. The airways can be divided into upper and lower airway systems. The transition between the two systems is located where the pathways of the respiratory and digestive systems cross, just at the top of the larynx.T

Where does gas exchange occur within the respiratory system?Multiple ChoiceIn the pharynxAt the alveoliIn the larynxIn the bronchioles
