這是有關於胃跟腸的一段英文文章

Ten small intestine, fills the central abdomen below the liver and stomach. The first 9¼inches(25 centimeters) in called the duodenum. Here the chyme is mixed with bile and pancreatic juices. Alkaline bile salts emulsify fat, increasing the surface area for enzyme action. Bile is stored in the gallbladder. Pancreatic secretions contain four enzymes: fat-splitting lipase; starch-breaking amylase and two that continue protein breakdown, but are activated only when they meet enterokinase, one of the six enzymes in the intestinal juice. Thus, carbohydrates are broken down into simple sugars such as glucose; proteins, into amino acids; and fats, into fatty acids and glycerol. All these are removed by the blood or lymphatic system. The intestinal wall provides a huge surface area for absorption, being folded and provided with villi, finger-like projections containing blood vessels and lacteals—lymphatic vessels originating in the villi.

    十小腸位在肝臟和胃的下方,整個下腹部中央都是十小腸。前面九又四分之一(25公分)的部分又稱為十二指腸。在這裡,食糜混合膽汁和胰液。鹼性的膽汁刺激脂肪的乳化,增加酵素活動的表面面積。膽汁儲存在膽囊裡。胰臟的分泌物包含了酵素,脂肪分離的脂肪分解酵素,澱粉破壞的澱粉酵素,和兩種蛋白質的分解。但是胰臟並不是活性化的,只有遇到腸液中六種酵素的其中一種腸活素才有作用。所以碳水化合物被分解成簡單的糖,例如葡萄糖,蛋白質則被分解成氨基酸,脂肪則是被分解成脂肪酸和甘油。這些都會被血液和淋巴系統帶離。折疊的且有絨毛的腸壁提供很大的表面面積做吸收,像手指的的投射,包含了血管和來自絨毛的淋巴血管的乳糜管。
