什么是胰液呢?胰液是由胰腺细胞分泌的液体。胰腺是兼有内分泌和外分泌功能的腺体器官,它有两根大导管开口于十二指肠。胰腺的外分泌称为胰液。胰液是无色、无臭的碱性液体(pH在7.6～8.2之间),每日分泌量约1～2升,具有很强的消化能力。胰液是由水、无机物和有机物组成。人胰液中无机物主要是高浓度的碳酸氢盐,它在消化过程中起着重要作用。因为它不仅能够迅速中和进入小肠的胃酸,保护肠粘膜免受酸的侵蚀,而且也为小肠内多种消化酶的活动提供了最适宜的酸碱环境。
What is pancreatic juice? Pancreatic fluid is secreted by pancreatic cells. The pancreas is a glandular organ that has both endocrine and exocrine functions. It has two large catheters open in the duodenum. Exocrine pancreas is called pancreatic juice. Pancreatic juice is a colorless, odorless alkaline liquid (pH between 7.6 to 8.2), the daily secretion of about 1 to 2 liters, with strong digestion. Pancreatic juice is composed of water, inorganic and organic matter. Inorganic fluid in human pancreatic fluid is mainly high concentration of bicarbonate, which plays an important role in the digestive process. Because it not only quickly neutralizes the stomach acid entering the small intestine, protects the intestinal mucosa from acid attack, it also provides the optimum pH-dependent environment for the activity of multiple digestive enzymes in the small intestine.
