Gastrointestinal development

Gastrointestinal development is the process by which the digestive system forms during early pregnancy. It begins around the third week, with the formation of the primitive gut from the embryonic tissue. Over time, this simple tube differentiates into specialized organs such as the stomach, intestines, liver, and pancreas. These structures grow, fold, and develop unique functions, ensuring the body can digest and absorb nutrients properly after birth. The process involves complex coordination of cell growth, movement, and differentiation, shaping a fully functional digestive system that supports health and growth.
