Step 1
Digestion
Answer
Digestion is the process of breaking down food into smaller components that can be absorbed by the body. This process involves both mechanical and chemical means to convert complex food substances into simpler forms, such as carbohydrates, proteins, and fats, allowing nutrients to be assimilated.
Step 2
Excretion
Answer
Excretion is the removal of waste products from the body, specifically substances that are no longer needed or are harmful. This includes the elimination of solid waste through feces, as well as liquid waste such as urine. Excretion ensures that harmful metabolic byproducts are adequately disposed of, maintaining the body’s internal balance.
