The alveoli are covered by a thin layer of epithelial cells and are surrounded by a network of capillaries. This structure, known as the alveolar-capillary membrane, facilitates the exchange of gases (oxygen and carbon dioxide) between the air in the alveoli and the blood in the capillaries. The thinness of this membrane is crucial for efficient gas diffusion.
what covers a cell?
The cornea.
The alveoli have a high surface tension due to a liquid film that covers their walls, making it difficult to inflate them. Additionally, the presence of surfactant helps to reduce surface tension in the alveoli, making inflation easier. When the alveoli are collapsed or have decreased compliance, it can also make it challenging to inflate them.

I am about sure it is called a root cap. :)

The shield that covers a decapod's cephalothorax is called the carapace. It is a hard, protective structure that covers the front part of the animal's body, including the head and thorax.
