How the food changes consistency and forms.
Our food changes in consistency and form through the action done by our digestive system. Here, they can be broken down into smaller pieces physically and chemically through digestion. Food and liquids are broken down into their smallest components during digestion so that the body may use them as fuel and building blocks for cells.
Food is mechanically broken down into tiny bits during physical digestion by being ground, smashed, squeezed, and churned as it travels through the digestive system. The food just breaks down into smaller bits of the same item; its form does not change. In the case of chemical digestion, particular enzymes or small proteins in the digestive system break down the food. The enzymes change the food's shape from one the body cannot utilize to one it can. The smaller organic molecules that makeup food are released when the bonds in the food particles are broken by chemical digestion. The body's cells can absorb the smaller organic molecules and utilize them for energy or other internal functions.
2. How the body could absorb the nutrients from the foods we eat.
The majority of the nutrients in your meal are absorbed in your small intestine before being transported by your circulatory system to other areas of your body for storage or utilization. The villi, which are minuscule projections, are responsible for this. Essential nutrients are extracted from the food that has been digested and has left your stomach by the microscopic, brush-like lining of the small intestine, which functions like a comb. In this procedure, water is also crucial. The small intestine extracts nutrients through a process known as diffusion. Water and water-soluble substances are transported over barriers, such as the villi in the small intestine, by diffusion. Once these nutrients have permeated the villi, they are immediately transported to the bloodstream. These nutrients can function in cells in this way to build proteins and release energy.
