In the early stages of pregnancy, the intestine develops within the umbilical cord. Weeks later it moves inside the foetus' abdomen. But where an unborn child has gastroschisis, the abdominal wall does not completely form. It results in the intestines growing outside the body. Around one in 3,000 babies are born with the condition in the UK, each year. As soon as the child is born the condition requires immediate treatment.
Since digestion occurs outside the cell, it is said to be extracellular. It takes place either in the lumen of the digestive system, in a gastric cavity or other digestive organ, or completely outside the body. The prefix 'extra' means outside, which tells us that extracellular digestion must occur outside the cell. During extracellular digestion, food is broken down outside the cell either mechanically or with acid by special molecules called enzymes.
