From the mouth, where digestion begins with saliva, to the stomach, where gastric juices work their magic, and finally to the small and large intestines, where nutrients are absorbed and waste is processed—every step is an incredible process. Learn how organs like the liver, pancreas, and gallbladder play vital roles in breaking down food and supporting digestion. This video breaks down the complex digestive system into simple, easy-to-understand steps.

Air enters through the nose or mouth, journeys down the throat, and reaches the lungs via tubes called bronchi. These bronchi split into smaller tubes, bronchioles, ending in tiny air sacs known as alveoli. Oxygen crosses the alveoli membrane into our bloodstream, while carbon dioxide moves from the blood into the alveoli, ready to be exhaled.
