Which of the following lists in order describes the process of digestion? Absorption, Elimination, and Tertiary: Which of these processes occurs first? The answer to this question depends on your knowledge of the human digestive system. Below, we’ll discuss each stage and why each of them is important for the body’s well-being. The following chart will guide you through these processes:


Food processing is divided into four stages: digestion, absorption, and extrusion. Each stage uses different organs and cellular processes. The first step is digestion, in which nutrients are broken down and transported throughout the body. The next step is absorption, where certain cells in the body take up small molecules, called metabolites. The last step is elimination, in which undigested matter is excreted.

Ingestion involves the processes in the mouth, such as chewing, grinding, and swallowing. Digestion breaks down the food, converting it into simpler molecules that can be absorbed into bodily fluids and tissues. Absorption occurs in the small intestine, which has villi lined against its walls. The absorption process is an essential part of the entire food-processing cycle.


When we eat, the body goes through a series of steps called digestion, absorption, and elimination. The first three steps take place in the mouth, where food is masticated by the teeth, tongue, and salivary glands. The bolus then travels down the alimentary canal and into the digestive organs. The digestive process takes place in a series of steps that break down complex macromolecules. Then, the bolus is digested, absorbing nutrients and becoming a digestible form. The final step is called elimination, which involves the excretion of metabolic waste. The urinary tract and kidneys are responsible for excreting these wastes.

After digestion, two more stages are necessary. In the absorption stage, certain cells absorb small molecules, while in the elimination stage, undigested material is excreted. The circulatory system carries nutrients through the body, while the elimination stage removes undigested materials. Each of the four stages of food processing is important for the health of your body. In addition to the mouth, esophagus, and stomach, the digestive system also includes the pancreas and the liver.


There are many different steps in the food processing process, starting with primary food processing, which involves cleaning, grading, and packaging, to tertiary food processing, which is the industrial production of ready-to-eat foods. The global processed food industry is worth USD 3.4 trillion, accounting for about three-fourths of the total global food market. With these improvements, health and convenience remain key value propositions.

Primary food processing involves the conversion of agricultural products into usable forms. Examples of this process include flour, maize, cheese, beer, and winemaking. Foods that undergo secondary food processing may include coloring and preservative agents. Some food products are fortified with vitamins and added salt. Some foods undergo tertiary food processing, such as frozen pizzas and packaged snacks. Listed below are some common examples of primary and secondary processing.

Third: The process of converting raw ingredients into ready-to-eat foods. The final product of primary food processing includes packaging, transportation, marketing, and sales to consumers. The fourth stage includes the final disposal of waste products. The fifth stage includes the final manufacturing of finished products. Food processing is the critical stage of the food production cycle. This stage of processing is most prevalent in large food companies. However, it is not required for the production of high-quality, wholesome food.
