Jab aap khana khate hain, saans lete hain aur chalte hain, to sharir ke andar ye saare kaam ek saath kaise hote hain? Khaane se pachan tantr bhojan ko upyogi poshak tatvon mein badalta hai. Saans lete samay phephde oksijan andar laate aur carbon dioxide baahar nikaalte hain. Hriday rakt ko poore sharir mein bhejta hai, taaki oksijan aur poshak tatv har hisse tak pahunchen. Mastishk sharir ki gatividhiyon ka taalmel banata hai, jaise chalne ke liye sharir ko sanket dena. Yahin samajh aata hai: sharir alag-alag angon ka dher nahin, balki lagataar saath kaam karne wali team hai. Har nivaala, har saans aur har kadam isi saajhe kaam ka nateeja hai. Isliye jawaab hai - maanav sharir kaam karta hai kyunki mastishk, hriday, phephde aur baaki ang ek judi hui team ki tarah lagataar milkar kaam karte hain.
