Digestive Health
There are many types of digestive disorders. In recent decades, there has been a significant increase in digestive diseases and disorders, food intolerances and allergies that has made us realize the importance of good digestive health. Poor diet, excess harmful chemicals in agriculture, water pollution, abuse of antibiotics, or excess hygiene are some of the causes.
Its function is to obtain the molecules necessary for the maintenance, growth and other energy needs of the body from the food eaten. Large molecules, such as proteins, lipids, complex carbohydrates, and nucleic acids, break down into smaller molecules that are absorbed through the lining of the digestive tract, especially in the small intestine.
Parietal Cells or oxyntic are a type of cell located at the top of the oxyntic glands of the stomach closely linked to hepatocytes and with the squamous cells of the esophagus is in common. This area is extremely dangerous because it’s where most cancers originate in the digestive system.
Proper functioning of the organs depends on the proper functioning of their cells. Older cells tend to be less efficient with age. Also, in some organs cells die and are not replaced; therefore, the number of cells decreases. The number of cells in the testes, ovaries, liver, and kidneys decreases markedly with age. When the number of cells becomes too low, the organ does not function normally. Therefore, most organs become less efficient with age. However, not all organs lose the same number of cells. The brain is an example of that. Healthy older people don’t lose a lot of neurons.
Deterioration in the function of one organ due to disease or aging can affect the function of another organ. For example, if atherosclerosis narrows the blood vessels in the kidneys, they will decrease in function because of reduced blood flow.
Often the first signs of aging are noticed in the musculoskeletal system. Then the eyes followed by the ears begin to change in early adulthood. Most of our internal functions also decrease with age. Our bodily functions reach their highest value shortly before age 30, and from then on a gradual but steady decline begins. Despite this decline, most of the functions remain correct because most organs have a functional capacity considerably higher than that required by the body (functional reserve). For example, if half of the liver is destroyed the remaining tissue is more than enough to maintain normal function. Therefore, it is diseases rather than normal aging, that explain the loss of functional capacity in advanced ages.
Some organs are more prone to malfunction than others; These organs include the heart and blood vessels, the urinary organs (such as the kidneys), and the brain.
