You will need to plug a computer up to the printer initially to set it up. Once the printer has been initialized and added to your network, you can unplug the computer and use the printer.
The alveolar epithelium comprises two main cell types: the alveolar type I and alveolar type II cell. The type I cell is a complex branched cell with multiple cytoplasmic plates that are greatly attenuated and relatively devoid of organelles; these plates represent the gas exchange surface in the alveolus.
They contain many pinocytotic vesicles. The remainder of the alveolar lining is made up of cuboidal Type II pneumocytes. These cells outnumber Type I cells, form tight junctions with Type I cells and divide to give rise to both Type I and Type II cells.Type II cells are characterized by lamellar bodies, which contain pulmonary surfactant, which is synthesized in the RER and is composed of a variety of lipids and proteins.Surfactant is released from Type II cells by exocytosis and coats the entire alveolar surface.hey contain many pinocytotic vesicles.
