Physiology
Ahmad ibn Abi al-Ash'ath described the physiology of the stomach in a live lion in his book ''al-Quadi wa al-muqtadi''. He wrote:When food enters the stomach, especially when it is plentiful, the stomach dilates and its layers get stretched...onlookers thought the stomach was rather small, so I proceeded to pour jug after jug in its throat…the inner layer of the distended stomach became as smooth as the external peritoneal layer. I then cut open the stomach and let the water out. The stomach shrank and I could see the pylorus…Ahmad ibn Abi al-Ash'ath observed the physiology of the stomach in a live lion in 959. This description preceded William Beaumont by almost 900 years, making Ahmad ibn al-Ash'ath the first person to initiate experimental events in gastric physiology.
