Physiology of stomach:- For understanding approaches for gastro retention‚ it is essential to overview gastric physiology and gastric motility. The stomach is situated in the left upper part of the abdominal cavity immediately under the diaphragm. Human stomach has a resting volume of 25-50ml‚ which can distend upto1500ml following a meal. It is divided into 5 anatomical parts: a) Cardia:- First part of the stomach below the esophagus. It contains cardiac spincter‚which is a thin ring of muscle

Active and passive transport are biological processes that move oxygen‚ water and nutrients into cells and remove waste products. Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. On the other hand‚ passive trasport moves biochemicals from areas of high concentration to areas of low concentration; so it does not require energy.
