Alveoli and Capillaries | The Lungs | GCSE Biology (9-1) | kayscience.com

In this video you will learn all the science for this topic to get a grade 9 or A* in your science exams! The alveolus has a one cell thick wall. The capillary also has a one cell thick wall. They both have a one cell thick wall to increase the rate of absorption of oxygen from the alveoli into the blood, and the diffusion of carbon dioxide out of the blood and into the alveoli. Another adaptation of both the capillary and the alveolus is that they both have a large surface area. A large surface area increases the rate of diffusion of gases in and out of the alveoli. Capillaries are one cell wide, which reduces the distance gases travel to the membrane All content, music, images, worksheets are the property of kayscience.com
