The information here should only be a guideline. Your doctor may provide you with other advise and your baby may have ideas of her own.For the first four to six months of your baby's first year all she will need is breast milk or formula. During this time she should start to be introduced to solids when she is ready.
The small intestine is the 'work horse' of digestion, as this is where most nutrients are absorbed. Peristalsis is also at work in this organ, moving food through and mixing it up with the digestive secretions from the pancreas and liver, including bile.ood is pushed through the esophagus and into the stomach by means of a series of contractions called peristalsis. Just before the opening to the stomach is an important ring-shaped muscle called the lower esophageal sphincter (LES).
After food is swallowed, it travels down the esophagus, a tube connecting your mouth to your stomach. The partially digested food is known as chyme. Once in your stomach, the food stimulates the release of substances (hormone regulators) that aid in digestion.he duodenum is a short funnel-shaped tube at the beginning of the small intestine. It receives chyme from the stomach, as well as enzymes from the pancreas and bile from the liver (delivered by the gallbladder) that help the body digest food.
