Digestive System Anatomy
消化系统解剖
In this video, we will take a quick look at the organs of the digestive system. Let's go!
在这段视频中，我们将快速了解消化器官。现在开始吧！
Mouth:
口腔：
The mouth is the entry point for food and the beginning of the digestive process. Food is broken down into smaller pieces by the teeth and mixed with saliva, which contains enzymes that start the process of breaking down carbohydrates.
口腔是食物的入口，也是消化过程的起始部位。食物被牙齿碾磨成小块，与唾液混合，唾液中含有启动碳水化合物分解过程的酶。
Esophagus:
食管：
The esophagus is a muscular tube that connects the mouth to the stomach. It uses rhythmic contractions called peristalsis to move food down to the stomach.
食管是一条连接口腔和胃的肌肉管。它通过称为“蠕动”的节律性收缩，将食物向下输送到胃。
Stomach:
胃：
The stomach is a muscular sac that churns and mixes food with gastric juices, which contain enzymes and hydrochloric acid that break down proteins and kill bacteria.
胃是个肌肉囊，它搅拌食物，将其与胃液混合，而胃液中含有分解蛋白质的酶和杀死细菌的盐酸。
Small intestine:
小肠：
The small intestine is a long, narrow tube where most of the nutrients from food are absorbed into the bloodstream. It receives digestive enzymes from the pancreas and bile from the liver to help break down food.
小肠是一段细而长的管，它将食物中的大部分营养物质吸收入血液。小肠接收来自胰腺的消化酶和来自肝脏的胆汁，来帮助分解食物。
Large intestine:
大肠：
The large intestine is a wider tube that absorbs water and electrolytes from undigested food, forming feces. The feces are eliminated from the body through the rectum and anus during bowel movements.
大肠是一段较粗的管，它从未消化的食物中吸收水分和电解质，形成粪便。在排便过程中，粪便通过直肠和肛门排出体外。
Pancreas:
胰腺：
The pancreas is an organ that produces digestive enzymes that break down carbohydrates, proteins, and fats in the small intestine.
胰腺是产生分解小肠内的碳水化合物、蛋白质和脂肪的消化酶的器官。
Liver:
肝脏：
The liver produces bile, which helps break down fats in the small intestine. It also helps detoxify harmful substances in the blood.
肝脏产生胆汁，帮助分解小肠内的脂肪。它也有排毒作用，帮助排出血液中的有毒物质。
Gallbladder:
胆囊：
The gallbladder is a small organ that stores bile produced by the liver and releases it into the small intestine when needed to help digest fats.
胆囊是储存肝脏产生的胆汁，并在需要时将其释放入小肠，帮助消化脂肪的一个小器官。
