The laptop doesn't tell the printer to print. The laptop tells the router to print, then the router tells the printer to print. 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.
The epithelial surface of the alveoli is composed of alveolar type I and type II cells. Alveolar type I cells comprise 96% of the alveolar surface area.These cells are extremely thin, thus, minimizing diffusion distance between the alveolar air space and pulmonary capillary blood.he epithelial surface of the alveoli is composed of alveolar type I and type 11 cells.
