TED-Ed: Oxygen's surprisingly complex journey through your body - Enda Butler

The video explains the complex process of oxygen transport in the human body. It highlights the roles of vital organs like the gut, brain, bones, lungs, blood, and heart in delivering oxygen to cells. Oxygen is crucial for aerobic respiration, producing ATP for cellular functions. Red blood cells, containing hemoglobin, transport oxygen, which is absorbed from the lungs. The brainstem controls breathing, expanding the lungs to intake air. The cardiovascular system, powered by the heart, circulates oxygen-rich blood throughout the body. This intricate system ensures efficient oxygen delivery, essential for life.
