Absorption is an interesting phenomenon in biology. It is to partake or absorb substances. In biology, the term absorption refers to the means by which nutrients and other substances are taken into the body, from the outside world into living, internal cells.
Understanding how absorption is carried out in the digestive system is almost like discovering hidden treasure. In the GI system, of course you depend on absorption to absorb what your body needs out of (the food). When that food is broken down further into smaller pieces in the stomach and small intestine, nutrients are absorbed into the blood. This then enables them to be delivered to cells in the body.
This mystical sensibility of food and nutrient absorption makes us realise how important it is to our health. If our body does not uptake its food properly, you will not get the nutrients that are so necessary to function well. It’s in the digestive system where vitamins, minerals, proteins, carbohydrates and sugars are absorbed to assist in the proper functioning of the body.
Absorption is also significant in medicine. General medicines are not designed to be absorbed into the body to work. But how medicine enters the body can be a little different depending on what kind it is — it can be swallowed, injected or spread onto the skin, for instance. Understanding how medications are absorbed informs our choices about our health.
To be well, we must maximize our absorption. By eating a varied diet rich in nutrients, drinking enough water and following medical advice when we are taking medicines, we can help our bodies to absorb more of what they need. This is as it should be, it’s good for our general health.
