Digestive System
The digestive system plays an important role in food digestion.
- Main organs: Mouth, esophagus, stomach, small intestine, large intestine, liver, gallbladder, and pancreas.
- Functions: It degrades food into smaller and smaller fragments until they can be absorbed into the body and used as energy. It then moves into the small intestine where the food is further digested by the bile juice secreted by the liver and the enzymes of the pancreas. At this stage nutrients are absorbed from the food and waste is eliminated.
Human Body
Human body is a single structure composed of billions of tiny components, which can be classified into four main groups: cells, tissues, organs, and systems. At the microscopic level, the cell is the most basic and fundamental unit that forms the foundation of the entire human body.
The human body is a highly organized system that performs various functions like movements, reproduction, growth, differentiation, respiration, digestion, and excretion. All these processes work together, in a balance, for the well-being of the individual and to sustain life.
