Question

Jab Hum Log oxygen Lete Hain To carbon dioxide kyu chodte Hain oxygen kyu nahi

Answer 1

When we breathe in we take in air and air contains 21% of oxygen and 0.03% carbon dioxide. As a result more amount of oxygen is taken in as compared to carbon dioxide.

When we breathe out most of the oxygen is absorbed by the body and else is exhaled out along with carbon dioxide.

Hope this helps you...

Answer 2

Aisa is liye hota hai kyoki hamare oxygen lene par hamare shareer mein present glucose jo ki hame bhojan se prapt hota hai wo glucose oxygen se kriya(react) karta hai aur parinam swaroop carbon di oxide ,water aur 38ATP energy ka utpad karta hai. Pani aur energy shareer istemal kar leta hai aur carbon dioxide nose se bahar aa jata hai.
