The simple squamous epithelial tissue lining the alveoli of lungs allows oxygen to enter the blood. These cells are thin and flat, reducing the distance for diffusion. This structure enables rapid exchange of oxygen and carbon dioxide between the air inside lungs and blood flowing through nearby capillaries, supporting efficient respiration and energy production in the body.
