@smart.doctor: Lungs & Airways Explained (3D) 🫁 - - Take a fast 3D tour through the respiratory system, from the upper airway down to the deepest air sacs in the lungs. You’ll see how air travels through the nose and throat, passes the larynx and trachea, branches into the bronchi and bronchioles, and finally reaches the alveoli where oxygen enters the blood and carbon dioxide leaves the body. Quick Facts (you’ll love these) 🫁 Your lungs contain roughly 300 million alveoli, creating a huge exchange surface area. 🌬 The diaphragm is the main breathing muscle and can move several centimeters with each breath. 🧪 Gas exchange happens across an ultra-thin “air–blood barrier” to make diffusion insanely fast. 📦 Not all inhaled air reaches alveoli, some stays in the “dead space” of the airways. 🧊 The pleura (lung lining) uses a thin fluid layer to reduce friction so lungs glide smoothly while you breathe. In this animation, the airway tree is shown clearly so you can understand the pathway of airflow and the key structures that keep breathing efficient and protected.
