To discuss:
The cell types and functions of alveoli, the relationship between pulmonary blood vessels and the alveoli, and the structure of the respiratory membrane in relation to its function.
Introduction:
The respiratory tract extends from the nose to the alveoli of the lungs. The bronchioles extend to form the alveoli of the lungs. An alveolus is a small sac that extends from the alveolar duct. The human lung has about 150 million alveolar sacs. The alveolus forms the respiratory zone that is predominantly involved in the exchange of gases such as oxygen and carbon dioxide by the process of diffusion to and from the blood.
