eral surface of the liver. 81 ▲ Function: stores and concentrate the bile Fundus 膽囊底 Body 膽囊體 Neck 膽囊頸 Cystic duct 膽囊管 膽囊分部 Cystic duct Neck Fundus Body ▲ The Gallbladder parts 82 Bile is secreted by the liver cells Common hepatic duct Common bile duct Major duodenal papilla 十二指腸大乳頭 Biliary ductuli膽小管 Right and left hepatic ducts Cystic duct Gallbladder (store, concentrate) 肝 臟 分 泌 膽 汁 流 經(jīng) 路 線 脂肪進(jìn)入小腸引起膽囊收縮,肝胰壺腹括約肌釋放 83 Bile salts (膽鹽 ) Bile pigments (膽色素 ) Cholesterol (膽固醇 ) Neutral fats (中性脂 ) Phospholipids (磷脂 ) Electrolytes (電解質(zhì) ) ▲② The position of the bile Composition of the bile 84 ① A yellowgreen, alkaline (堿性的 ) solution ▲ Special points for the bile ② Bile salts are cholesterol (膽固醇 ) derivatives that: Emulsify (使乳化 ) fat Facilitate fat and cholesterol absorption Help solubilize (溶解 ) cholesterol ③ The chief bile pigment is bilirubin (膽紅素 ), a waste product of the heme(血紅素 ). 85 Acidic, fatty chyme (酸性脂質(zhì)食糜 ) ▲ ③ The regulation of the bile release The duodenum release Cholecystokinin (縮膽囊肽 ) and secretin(促胰液素 ) into blood Bile salts and secretin transported in blood stimulate the liver to produce bile Vagal(迷走神經(jīng)的 ) stimulation causes weak contractions of the gallbladder Cholecystokinin (縮膽囊肽 ) The gallbladder to contract The gallbladder The bile enters the duodenum hepatopancreatic(肝胰的 ) sphincter to relax 86 Enteroendocrine cell: 腸內(nèi)分泌細(xì)胞 Vagal: 迷走神經(jīng)的 Cholecystokinin: 縮膽囊肽 Secretin: 促胰液素 Hepatopancreatic: 肝胰的 The regulation of the bile release 87 167。 ⒊ The Pancreas 胰 ▲ The Shape A soft yellowish lobulated gland. ▲ Position Lies behind the peritoneum (腹膜 ) on the posterior abdominal wall, roughly at the level of L1~L2. 88 ▲ Pancreas is divided into three parts 胰分部 Head 胰頭 Body 胰體 Tail 胰尾 89 Main Pancreatic duct 主胰管 Accessory pancreatic duct 副胰管 ▲ Pancreatic duct 胰管 胰管類型 主胰管自胰尾起沿胰的長軸右行,沿途匯集各葉的導(dǎo)管,最后與膽總管末端匯合成肝胰壺腹,開口于十二指腸大乳頭。 有時(shí)在主胰管上方有細(xì)小的副胰管,開口于十二指腸小乳頭 主胰管 副胰管 90 The regulation of the pancreatic secretion Chyme: 食糜 Enteroendocrine cell: 腸內(nèi)分泌細(xì)胞 Vagal: 迷走神經(jīng)的 Cholecystokinin: 縮膽囊肽 Secretin: 促胰液素 Hepatopancreatic: 肝胰的 Bicarbonate: 碳酸氫鹽 Cephalic:頭的 ,顱的 91 Section 4 復(fù)習(xí) 提問 總結(jié) Answer: The mouth The pharynx The esophagus The stomach The small intestine: Duodenum。Jejunum。 Ileum The large intestine: Cecum 盲腸 。 Vermiform appendix 闌尾 。 Colon 結(jié)腸 。 Rectum 直腸 Anal canal 肛管 Question 1: What are the position of the digestive duct? 92 Question 2: What are the structure of the liver? Answer: Hexagonalshaped liver lobules are the structural and functional units of the liver. The liver lobules are mainly posed of hepatocytes (肝實(shí)質(zhì)細(xì)胞 ) Kupffer cells are distributed in the wall of the hepatic sinusoid (肝血竇 ) 93 Exercise Requirement: answer every question in English. ⒈ Term explanation Hard and soft palate(硬腭和軟腭 ) Deciduous and permanent teeth (乳牙與恒牙 ) Vermiform appendix(闌尾 ) Common bile duct(膽總管 ) ⒉ Briefly stating the ponents of the alimentary system and its functions.(簡述消化系統(tǒng)的組成與功能 ) 94 95 謝 謝 聆 聽! 歡 迎 指 導(dǎo)!
