The journey of a meal
- The food you eat is too big for your cells to use. It must be broken down and absorbed.
- That's the job of the digestive system 消化系统 — a long tube with specialised parts.
一餐的旅程
- 你吃的食物对你的细胞来说太大了,无法使用。它必须被分解和吸收。
- 那是消化系统(digestive system)的工作——一根有专门部分的长管。
Put these parts of the gut in the order food passes through them. · 把肠道的这些部分按食物经过它们的顺序排列。
Mouth → oesophagus → stomach → small intestine → large intestine. · 口 → 食道 → 胃 → 小肠 → 大肠。
Food is moved along the gut by waves of muscle contraction called: · 食物被叫做以下哪种的肌肉收缩波沿肠道推进:
Peristalsis squeezes food along the gut. · 蠕动把食物沿肠道挤压。
The main organs
- Mouth → oesophagus 食道 → stomach → small intestine 小肠 → large intestine.
- Food is moved along by waves of muscle contraction called peristalsis 蠕动.
The alimentary canal that food passes through, plus the organs that add digestive juices
主要器官
- 口 → 食道 → 胃 → 小肠 → 大肠。
- 食物被叫做蠕动(peristalsis)的肌肉收缩波沿管推进。
食物经过的消化道,加上加入消化液的器官
Through the digestive system · 穿过消化系统
Food travels along the gut; each part does a different job to break it down and absorb it. · 食物沿肠道行进;每个部分做一个不同的工作来分解和吸收它。
The pancreas makes: · 胰腺制造:
The pancreas produces enzymes; the liver makes bile. · 胰腺产生酶;肝制造胆汁。
The organ that produces bile is the . · 产生胆汁的器官是。
The liver makes bile; the gall bladder stores it. · 肝制造胆汁;胆囊储存它。
Helper organs
- The liver 肝脏 makes bile 胆汁; the gall bladder stores it.
- The pancreas 胰腺 makes digestive enzymes.
辅助器官
- 肝(liver)制造胆汁(bile);胆囊(gall bladder)储存它。
- 胰腺(pancreas)制造消化酶。
Egestion is the removal of undigested food (faeces). · 排遗是移除未消化的食物(粪便)。
Egestion removes the waste food that was never absorbed. · 排遗移除从未被吸收的废弃食物。
Key stages
- Ingestion 摄入 (taking in), digestion (breaking down), absorption 吸收 (into the blood), egestion (removing waste).
Worked example. A piece of bread is chewed (mouth), churned with acid (stomach), digested by enzymes (small intestine), absorbed into the blood, and the leftover fibre is egested. Each organ has its role.
关键阶段
- 摄入(ingestion,吃进去)、消化(digestion,分解)、吸收(absorption,进入血液)、排遗(egestion,移除废物)。
例题。 一块面包被咀嚼(口),与酸一起搅拌(胃),被酶消化(小肠),吸收进血液,剩余的纤维被排遗。每个器官都有它的角色。
You've got it
- the gut: mouth → oesophagus → stomach → small intestine → large intestine; moved by peristalsis
- the liver makes bile; the pancreas makes enzymes
- stages: ingestion → digestion → absorption → egestion
你掌握了
- 肠道:口 → 食道 → 胃 → 小肠 → 大肠;由蠕动推进
- 肝制造胆汁;胰腺制造酶
- 阶段:摄入 → 消化 → 吸收 → 排遗
