How Lungs Work – Breathing Process, Gas Exchange, Oxygen Transport, Alveoli Function and Diseases

How do lungs work and how does breathing actually keep you alive? This video explains the full process of respiration in the human body, including how air enters the lungs, how gas exchange occurs in the alveoli, and how oxygen is transported through the blood by hemoglobin to every cell. Learn how oxygen is used inside mitochondria to produce energy and how carbon dioxide is removed from the body. The video also explains the physics of breathing, including the role of the diaphragm, pressure changes in the chest, and automatic control of respiration by the brain. In addition, it covers what damages the lungs, how diseases like asthma, emphysema, and pneumonia affect breathing, and why healthy lungs are essential for survival. A complete and easy-to-understand explanation of how the respiratory system works. #lungs #breathing #howitworks #science #biology #humanbody #health #oxygen #medical #education
