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 chewing food and swallowing it, it passes through the stomach and small intestine over a period of 4 to 7 hours. The time passing through the large intestine is much longer, averaging about 40 hours. For men the average time to digest food is shorter overall than it is for women. Having a digestive condition that affects transit time (the time it takes for food to pass through the digestive system) can shorten or extend the time.
