水的一問(20)

１．先答由飽變得更加飽．．．
當你飲左水後．．．你個胃當然會漲大．．．．
我地之所以會覺得”頂住個胃．．係因為個胃ｄ　ｍｕｓｃｌｅ　受到壓力．．．因而ｃｏｎｔｒａｃｔ．．．我地個胃有ｓｔｒｅｔｃｈ　ｒｅｃｅｐｔｏｒ（感應肌肉收縮的感應器官）　．．．所以會有ｓｔｉｍｕｌａｔｉｏｎ（ｎｅｒｖｅ　ｉｍｐｕｌｓｅｓ～神經脈衝）　叫我地停止食野．．．以保護我地個胃部．．．所以我地會更飽．．．．（應該係話令我地有飽ｏ既感覺所以停止進食．）

２．但點解飲水唔飽．．．我地肚餓係因為身體唔夠能量．．．亦是受到人的身理時鐘所影響．．．ｅ．ｇ．在某一時候胃部就會分泌胃酸．．．準備進食．．．
肚餓ｏ既感覺係受人體的荷爾蒙～ghrelin所導致．．．你飲水係唔會有能量吸收．．．所以身體繼續分泌ghrelin．．．令你肚餓．．等你去食多ｄ野補充能量．．．
冇錯．．雖然個胃都有漲大．．．但事實上荷爾蒙的影響會比ｓｔｒｅｔｃｈ　ｒｅｃｅｐｔｏｒ的影響大．．．所以你會覺得肚漲但唔會飽．．．直至你真的進食．．．ghrelin才開始減少．．．

飽ｏ既感覺由荷爾蒙～leptin　導致．．．
餓ｏ既感覺由荷爾蒙～ghrelin　導致．．．係第１個ｃａｓｅ．．．因為你已飽．．．
leptin增加就分泌．．．ghrelin就減少分泌．．．所以ｓｔｒｅｔｃｈ　ｒｅｃｅｐｔｏｒ的影響就比較大．．．

由飽變得更加飽:食團吸水漲大,食團消化完先會去小腸
唔可以令你由唔飽變得飽:人體不會把水份停留在胃消化,因為冇必要

when you are full, your stomach will try to prevent the food leave it too quickly, because of needing time to digest. this as well prevent the water adsorbed by food leave the stomach.

while, when your stomach is empty, the pyloric muscle at the exit side(幽門) relax and water leave your stomach easily.
