Why is fiber necessary for proper functioning of the digestive system?

The undigested fiber creates “bulk” so the muscles in the intestine can push waste out of the body. Eating enough fiber helps prevent constipation.

Why the process of digestion is necessary for providing cells with their requirements?

Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair.

How does the digestive system supply the cells with the nutrients they need?

The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.
