ANATOMY

Detailed explanation-1: -Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.

Detailed explanation-2: -Answer: The air in the alveoli is called Alveolar Air.

Detailed explanation-3: -From the alveoli, air moves out of the lungs through the bronchioles and bronchi.

Detailed explanation-4: -The bronchi divide into smaller branches called bronchioles. And at the end of each bronchiole is a small duct (alveolar duct) that connects to a cluster of thousands of microscopic bubble-like structures, the alveoli. The word alveolus comes from the Latin word for “little cavity.”

Detailed explanation-5: -Inspiration. Inspiration (inhalation) is the process of taking air into the lungs. It is the active phase of ventilation because it is the result of muscle contraction. During inspiration, the diaphragm contracts and the thoracic cavity increases in volume.
