Digestion. Digestion of food is a form of catabolism, in which the food is broken down into small molecules that the body can absorb and use for energy, growth, and repair. Digestion occurs when food is moved through the digestive system. It begins in the mouth and ends in the small intestine. The final products of digestion are absorbed from ...

May 1, 2023 · Digestion is the chemical breakdown of the ingested food into absorbable molecules. Absorption refers to the movement of nutrients, water and electrolytes from the lumen of the small intestine into the cell, then into the blood. In this article, we will look at the digestion and absorption of carbohydrates, protein and lipids.
Aug 14, 2020 · Eggs are a good dietary source of protein and will be used as our example to describe the path of proteins in the processes of digestion and absorption. One egg, whether raw, hard-boiled, scrambled, or fried, supplies about six grams of protein. Figure 5.4.1: The egg is a good dietary source of protein. White, speckled (red), and brown chicken ...
Chemical digestion, on the other hand, is a complex process that reduces food into its chemical building blocks, which are then absorbed to nourish the cells of the body (Figure 23.7.1). In this section, you will look more closely at the processes of chemical digestion and absorption. Figure 23.7.1 – Digestion and Absorption: Digestion begins ...

Sep 12, 2022 · Digestion is the process of mechanically and enzymatically breaking down food into substances for absorption into the bloodstream. The food contains 3 macronutrients that require digestion before they can be absorbed: fats, carbohydrates, and proteins. These macronutrients are broken down through digestion into molecules that can traverse the intestinal epithelium and enter the bloodstream for ...

Jul 30, 2022 · Absorption can occur through five mechanisms: (1) active transport, (2) passive diffusion, (3) facilitated diffusion, (4) co-transport (or secondary active transport), and (5) endocytosis. As you will recall from Chapter 3, active transport refers to the movement of a substance across a cell membrane going from an area of lower concentration to an area of higher concentration (up the ...

Oct 28, 2023 · Nutrient absorption - This comes after the breakdown of carbohydrates, proteins, fats, vitamins, and minerals, which are essential for energy production, growth, and cellular maintenance. Egestion of waste and toxins - The process eliminates indigestible components and harmful substances from the body.
