| Video Discription | Flash cards every weekday: https://www.instagram.com/igcsebioflashcards The alveoli ("many alveoli", "one alveolus") are the sites of gas exchange in the lungs. They are tiny air sacks sometimes described as being cauliflower-shaped. Oxygen diffuses across the lining of the alveoli and blood capillaries into and into red blood cells. Carbon dioxide diffuses from the blood to the alveoli. A concentration gradient is maintained by breathing as well as blood flow. The main adaptation of the gas exchange surface are: 1. Large surface area 2. Thin wall 3. Moist lining 4. Good blood supply 5. Good ventilation [mZvzl8KH6iI] |
