The small intestine is the body's most important digestive organ. It performs both chemical and mechanical digestion and is the main site of absorption.
Explanation:
The small intestine measures about 20 feet, and is divided into duodenum, jejunum and ileum. 90% of absorption of nutrients and minerals take place in the small intestine, and the remaining 10% in the stomach and large intestine.
The inner hair cells transform the sound vibrations in the fluids of the cochlea into electrical signals that are then relayed via the auditory nerve to the auditory brain stem and to the auditory cortex.
