calcium or more per day delivered fewer preterm babies than those women with a lower calcium intake. Calcium supplementation did not have a detectable effect on the risk of low birth weight, admissions to neonatal intensive care unit, stillbirths or neonatal death before hospital discharge.
The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. In chemical digestion, enzymes break down food into the small molecules the body can use.
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.Digestion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and chemical digestion.n certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.
