Video narration
School ki canteen mein aapke tiffin ka ek niwala abhi-abhi munh mein gaya hai. Yeh sharir ke kaam kaise aayega? Munh mein daant use chabaate hain, aur laar digestion ki shuruaat karti hai - bhojan tootne lagta hai. Bhojan-nali se niwala pet mein pahunchta hai. Pet use mathata hai; acid aur enzymes use aur todte hain. Lekin pet antim padaav nahin hai. Asal mod: adhiktar nutrients ka absorption, yani poshak tatvon ka rakt mein jaana, pet ke baad small intestine, yani chhoti aant, mein hota hai. Wahin digestion poora hota hai aur upyogi nutrients rakt mein pahunchte hain. Bacha padarth large intestine, yani badi aant, mein jaata hai. Wahan paani aur salts wapas sharir mein avshoshit hote hain. Baaki apashisht bankar baahar nikalta hai. Isliye school ke usi meal ko yaad rakhiye: digestion bhojan ko nutrients mein badalta hai, aur small intestine unhen blood tak pahunchati hai.
