The lungs are connected to the trachea by bronchi (option A).

Explanation:

The respiratory system is in charge of allowing the breathing process, which consists of obtaining oxygen from the air to pass it to the blood, which transports it to the tissues. This apparatus is made up of the upper respiratory tract and the bronchis and lungs.

The aspirated air enters through the upper respiratory tract —nose, pharynx, larynx and trachea— from where it is passed to the lungs. When it is near the lungs, the trachea forks to form the bronchi, which represent the union between trachea and lungs.

The bronchi branch out into the lungs, ending in the pulmonary alveoli, which are responsible for diffusing oxygen into the blood.

    The other options —windpipes, alveoli or capillaries— are not in charge of joining the trachea to the bronchial tubes.
