👨‍⚕️ Dr. BOSS 的聊天室｜Episode 02-3：迴腸 BOSS Doctor’s Chatroom｜Episode 02-3: The Ileum 副標 / Subtitle 👨‍⚕️ Dr. BOSS × 🐨 Koala | 迴腸：養分吸收與最後防線 👨‍⚕️ Dr. BOSS × 🐨 Koala | Ileum: Nutrient Absorption and the Last Defense Line --- 🟦 對話稿 Dialogue（中英對照） Koala： BOSS醫生，迴腸跟空腸差別大嗎？ Doctor BOSS, is the ileum very different from the jejunum? BOSS 醫生： 迴腸主要吸收空腸未完全吸收的養分，特別是維生素B12、膽鹽和水分。它也是小腸的最後防線，將殘渣送往大腸。 The ileum primarily absorbs nutrients not fully absorbed by the jejunum, especially vitamin B12, bile salts, and water. It also acts as the small intestine’s last defense, sending residues to the large intestine. Koala： 那迴腸有什麼特殊結構嗎？ Does the ileum have any special structural features? BOSS 醫生： 是的！迴腸內壁同樣有絨毛和微絨毛，但比空腸略少，腸腔略小，並且有佩氏斑（Peyer’s patches），幫助免疫防禦。 Yes! The ileum also has villi and microvilli, though slightly fewer than the jejunum. Its lumen is narrower, and it contains Peyer’s patches, which help with immune defense. --- 🟦 結構篇 Structure（中英對照） BOSS 醫生： 迴腸的主要特點如下： Key features of the ileum: 1. 絨毛 Villi 中文：比空腸略少，但仍負責養分吸收 English: Slightly fewer than jejunum but still responsible for nutrient absorption 2. 微絨毛 Microvilli 中文：覆蓋絨毛表面，提高吸收效率 English: Cover the villi surface to enhance absorption efficiency 3. 佩氏斑 Peyer’s patches 中文：免疫組織，監測腸道病原 English: Immune tissue that monitors intestinal pathogens 4. 狹窄腸腔 Narrow lumen 中文：有助於延長食物停留時間，增加養分吸收 English: Helps prolong food residence time, increasing nutrient absorption --- 🟦 日常使用 Daily Use（中英對照） Koala： 迴腸每天都在做什麼呢？ What does the ileum do daily? BOSS 醫生： 一句話：迴腸 = 最後養分吸收與免疫防線 In short: Ileum = final nutrient absorption and immune defense 舉例 Examples: 吸收剩餘養分 Absorbing remaining nutrients 吸收維生素B12 Absorbing vitamin B12 回收膽鹽 Reabsorbing bile salts 吸收水分 Absorbing water 將殘渣送到大腸 Moving residues to the large intestine --- 🟦 習慣與保養 Habits & Care（中英對照） BOSS 醫生： 迴腸健康常見問題： Common issues affecting ileum health: 長期腹瀉或便秘 Chronic diarrhea or constipation 高脂高糖飲食 Excessive fat and sugar intake 慢性腸道炎症 Chronic intestinal inflammation 免疫功能失衡 Immune dysfunction 改善方式 Tips for Improvement: 攝取膳食纖維與益生菌 Dietary fiber and probiotics 維持規律飲食 Regular meals 多喝水 Hydration 保持生活作息規律 Maintain regular lifestyle --- 🟦 小知識 Mini Note（中英對照） Koala： 為什麼迴腸很重要？ Why is the ileum important? BOSS 醫生： 迴腸不只是吸收最後養分，它的佩氏斑還負責腸道免疫，保護身體免受病原侵害。 The ileum not only absorbs the last nutrients but its Peyer’s patches also provide intestinal immune defense, protecting the body from pathogens.
