Question

Intake of food is called
A. Ingestion
B. Egestion
C. Digestion
D. Nutrition

Answer 1

Hint:Food consumption is very important because it provides energy, encourages development and preserves an individual's life. The total consumption of food is the amount of food you are currently eating.

Complete answer:
The consumption of food is the ingestion of any product consisting of carbohydrates, proteins, fats, vitamins and minerals.Ingestion, a method in which food is ingested through the mouth and broken down by teeth and saliva, is the first step to acquiring nutrition.

A multi-step method is to obtain nutrition and energy from food. For animals, ingestion, the act of taking in food, is the first step. The cell membranes will not move through the large molecules present in intact food. Food needs to be divided into smaller fragments so that the nutrients and organic compounds can be harnessed by animals.

Ingestion of food through the mouth is the first step in this process. The teeth, saliva, and tongue play important roles in chewing (preparing the food into a bolus) once in the mouth. Mastication or chewing is an extremely important part of the digestive process, particularly for fruits and vegetables, as they have indigestible cellulose coats that need to be physically broken down.

In addition, digestive enzymes only operate on food particles' surfaces, so the smaller the particle, the more successful the digestive process is. While the food is being broken down mechanically, the saliva enzymes also begin to process the food chemically.

These processes' combined action modifies the food from large particles to a soft mass that can be swallowed and can travel the length of the esophagus.Other substances, like drugs (where ingestion is called oral administration), and substances deemed inedible, such as insect shells, can be consumed in addition to nutritional products.

Hence,the correct answer is option A.

Note:Ingestion is also a popular route taken into the body by pathogenic organisms and poisons. Viruses, bacteria, and parasites include certain pathogens transmitted by ingestion. This takes place most commonly through the fecal-oral pathway. An intermediate stage, such as drinking water contaminated by feces or food prepared by workers who do not practice proper hand-washing, is often involved.
