The digestive system aids in absorbing nutrients from meals that are required for our bodies' growth, maintenance, and energy. We eat to fuel our bodies. It takes a while to get from eating food to having energy! However, this page aids in your comprehension of the entire digestive process, including what digestion is, the components of the digestive system, associated glands, and more.
Large food molecules are broken down into smaller, more absorbable molecules during digestion, a catabolic process carried out in the digestive tract with the aid of digestive enzymes.
For instance, glucose is created when carbs are broken down into simple sugars. These smaller molecules are subsequently taken up by the cells and absorbed into the blood or lymph. The cell uses these up in order to create ATP, which is a source of energy.
The process of digestion and nutrition are intimately related. Food contains essential elements that our bodies require for growth and maintenance, such as carbs, proteins, and lipids. The digestive system converts these complicated nutrients into their simpler form because the body cannot directly utilize them.
Similar to how fats and lipids are broken down into fatty acids and glycerol and carbs into simple sugars, proteins are sequentially broken down into amino acids in the digestive tract or alimentary canal. Now that nutrients are available in simpler forms, the body is able to absorb them and use them to make energy.
