Explain the digestive system in human beings

The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder.

The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.

The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus.

The liver, pancreas, and gallbladder are the solid organs of the digestive system.

They work together to digest and absorb the food that we consume which is of course vital for life and growth.
