WebIn both lungs of an adult there are about 300 million alveoli. If they were all flattened out their surface area would be about 50 sq metres when the lungs have breathed out, and up to 150 square metres when they breathe in. The total area of the capillary blood vessels around all the alveoli is about 100 square metres. Webnumber: there are around 700 million alveoli - ie 350 million per lung; the total surface area of the alveoli is around 70 m 2 - capillaries cover 70 per cent of the surface of the alveoli

WebAlveoli are the tiny air sacs found at the end of bronchioles in your lungs. Gas exchange occurs here. Oxygen moves into the blood and carbon dioxide is removed. WebAlveoli are found in small clusters called alveolar sacs at the end of the terminal bronchiole. Each alveolus is a hollow, cup-shaped cavity surrounded by many tiny capillaries. The walls of the alveolus are lined with simple squamous epithelial cells known as alveolar cells. WebLarge surface area - many alveoli are present in the lungs with a shape that further increases surface area.
