Simple Squamous Epithelial Tissue forms the surface of the alveoli
simple squamous, it helps with the simple passive diffusion as it is only one cell thick i believe.

Type 1 alveolar cells
function of type 2 alveoli cells is to secrete surfactant.
Pseudostratified columnar cells line the inside of the trachea and simple squamous cells make up the alveoli
That is correct. Alveoli only contain only two types of cells: Type I cells that are like thin sheets and make up the actually wall of the alveoli, and Type II cells that secrete a substance called surfactant that helps to hold the alveoli open. There can also be some macrophages present in the alveoli to destroy invading bacteria.
Type 2 Alveolar cells
Pneumocyte. There are two types: Type I cells make up the lining of the air sacks (alveoli) in the lung, type II cells produce a slick liquid called surfactant that helps coat the alveoli and keep them from collapsing when we exhale.
Pulmonary alveoli cells
Alveoli does not collapse because lungs always have a residual volume which prevents the alveoli to collapse.
Oxygen is transferred to blood cells in the capillaries around the alveoli. It diffuses from the alveoli into the bloodstream, and to the hemoglobin molecule.
By the lungs and alveoli.
they are involved in keeping alveoli from collapsing
No, alveoli consist of flattened epithelial cells which make the diffusion rate faster (by the reducing the distance the path that oxygen has to diffuse through).
