The small intestine consists of three parts – the duodenum, the jejunum and the ileum. This organ is proceeded in the gastrointestinal tract by the stomach and terminates at the beginning of the large intestine also known as the caecum.
The small intestine receives signals from external or extrinsic sources, which come from the brain. As well as internal or intrinsic sources, which come from within the small intestine itself. These neural inputs allow for the function of the gastrointestinal tract to be achieved. That includes motility, secretomotor function of glands in the GI tract, regulation of blood flow and immunomodulation, which is the regulation of the immune system within the small intestine.
In the full version of this video, we will cover the following:
