The Digesitive System:from meals to molecules
．all plant &animal life is made up of ceels,which form tissues that compose
the organs &organ systems
．the food we eat is digested in the gastrointestinal tract
& nutrients are absorbed into the body
．hormones released into the blood & enzymes released into the gastrointestinal
tract facilitate the digestion of food & the absorption of nutrients
．Digestion begins in the mouth
．The small intestine is the primary site of digestion & absorption
．Water-soluble materials are absorbed into the blood.Most fatsoluble materials
are absorbed into the hymph
．Change in the gastrointestinal tract can alter digestion and absorption and
affect nutritional status.
．Digestion is the process of breaking food into components small enoufh to
be absorbed into the body.
．Most of the carbohydrate is digested to sugars, the protein to amino acids,
and the fat to fatty acids.
(Fatty acids are chains of carbon atoms that are often present as components
of larger molecules knows as triglycerides(三酸甘油脂) , which we commonly
call fats.)
．Gallbladder is necessary for fat digestion and absorption
．The main part of the digestive system is the gastrointestinal tract= GI
tract,gut,digestive tract, intestinal tract, or alimentary canal.
．While in the stomach , the bolus is mixed with highly acidid stomach
secretions to form a scmiliquid fppd ,ass ca;;ed chyme.
．While most of the justrointestinal tract is surrounded by two layers of
muscle, the stomach contains a third layer, allowing for powerful contractious
that thoroughly churn and mix the stomach contents.
. 蛋白質主要在為胃消化
糖在嘴巴就開始分解消化
脂肪則在小腸開始消化
．Digestive
(1)includes: mouth, esophagus, homach, intestines, pancreas, liver, and gallboadder.
(2)ingests and digests food, absorts nutrients into the blood.
．The human body is made up of 4 tissues:
muscle, nerves, epithelial, and connective.
mucosa 管壁黏膜
connective tissue 結締組織(包含 nerves ,blood vessels）
lumen 腸腔
antigen 抗原
immune system 免疫系統

antibodies 抗體
allergic reactions 過敏反應
gastric juice 胃酸 (含hydrochloric acid 鹽酸 和 pepsin 胃蛋白分解酉每)
peptic ulcer 胃潰瘍
motility 胃蠕動
churn 消化
gastrin 胃素
small intestine 小腸
pancreas 胰臟
gallbladder 膽囊(汁)
pancreas juice (含bicarbonate 制酸劑 , digestive enzyme)
arteny 動脈
vein 靜脈
lymph 淋巴
lacteral 微血管
portel vein 肝門脈
heart burn 火燒心（胃酸倒流）
gastroesophageal reflux（倒流） disease 腸胃倒流疾病
salivaty glands 唾液腺(分泌澱粉分解酵素)
