They have alveoli which are small air sacs. Alveoli give the lungs a big surface area, meaning that more oxygen can diffuse from the lungs into the blood stream, and more waste gases from the blood into the lungs. Further, they are moist, covered in surfactant which reduces surface tension throughout the lung. the pursuit of happiness作文 https://boatshields.com
