人的胰(Pancreas)位于腹膜的后面,附着在十二指肠的旁边,它是一种复泡状腺体。猪胰与人胰略不同它位于最后二根胸椎和第一、第二根腰椎的复侧,从外形来看,它可分为胰头和左、右两叶。胰的外面没有明显的被膜,仅覆以薄层疏松的结缔组织。结缔组织深入腺内,把整个胰腺分成很多小叶,小叶间的结缔组织中有血管、淋巴管、神经和导管。胰腺很特殊,它既是内分泌腺又是外分泌腺,现简单从这二方面将胰的形态结构及其生化特征作一介绍: 外分泌腺(exocrine glands) 胰的外分泌腺包括导管和腺泡,它的分泌产物是胰液,内含多种消化酶,因此胰腺是重要的消化腺。一、导管(duct) 腺泡连于一段细长的导管称之闰管,胰腺 Pancreas, located behind the peritoneum and attached to the duodenum, is a vesicular gland. Porcine pancreas and human slightly different slightly it is located in the last two thoracic and the first and second lumbar complex side, from the appearance point of view, it can be divided into pancreatic head and left and right leaves. There is no obvious outer membrane of the pancreas, only covered with loose connective tissue. Connective tissue deep into the gland, the entire pancreas is divided into many leaflets, connective tissue between the lobular vessels, lymphatic vessels, nerves and catheters. Pancreas is very special, it is both endocrine and exocrine glands, is now simple from these two aspects of pancreatic morphological structure and biochemical characteristics of an introduction: Exocrine glands Pancreatic exocrine glands include ducts and acinar, which Secretory products are pancreatic juice, containing a variety of digestive enzymes, so the pancreas is an important digestive gland. First, the duct (duct) Acinar connected to a section of elongated catheter called the intercostal tube, pancreas
