Answer:
When group of tissues are formed from a cell layer of squamous cell,then the epithelium formed is said to be simple squamous epithelium.These cells are tightly packed together,to form the lining of the cell surface.Thus they are in directs contact with the basement membrane underlying the cell structure. Therefore,they act as selectively membrane structure for osmosis,diffusion,This explain their presence in the alveolar and kidney,where filtration takes place
In additions ,due to their one cell layer thickness,they form the lining of fragile of delicate body cavities. e.g the alveolar in the lungs, lymphatic vessels,and inner lining of the wall of the heart.
Besides they also contain membrane proteins,which aids the control of substances across their walls of tight junctions.Thus ions, molecules passages is regulated
