Skeletal muscles, attached to bones and tendons, help us move voluntarily and quickly. Cardiac muscles, found only in the heart, work involuntarily and at a moderate speed to keep our heart beating. Smooth muscles, found in hollow organs and blood vessels, work slowly and involuntarily to control functions like digestion and blood flow. Each muscle type has a unique cellular structure.

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.
