Question
How are the activities of gastrointestinal tract regulated?
✓
Answer
The activities of the gastrointestinal tract are under neural and hormonal control for proper coordination of different parts:
- The sight, smell and/ or the presence of food in the
oral cavity can stimulate the secretion of saliva. - Similarly, gastric and intestinal secretions are also
stimulated by neural signals. - The muscular activities of different parts of the
alimentary canal can also be moderated by neural
mechanisms (both local and through CNS). - Hormonal control of the secretion of digestive juices
is carried out by local hormones produced by the
gastric and intestinal mucosa.
