Detailed explanation-1: -The components of food such as carbohydrates are complex substances. These complex substances cannot be utilised as such by the body. So, they are broken down into simpler substances which are easy to absorb.
Detailed explanation-2: -Digestion is the process of breakdown of complex food substances into simpler substances. Secretion of various glands like stomach, salivary gland, pancreas, liver and intestinal gland are involved in this process.
Detailed explanation-3: -So, the correct answer is ‘Digestion’.
Detailed explanation-4: -Lipids, proteins, and complex carbohydrates are broken down into small and absorbable units (digested), principally in the small intestine. The products of digestion, including vitamins, minerals, and water, which cross the mucosa and enter the lymph or the blood (Absorption).
Detailed explanation-5: -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.
