نویسنده
چکیده مقاله:
تنفس یکی از اساسی ترین نیازهای انسان است که در صورت عدم تأمین این نیاز، حیات انسان چند دقیقه ای بیشتر ادامه نخواهد یافت. اهمیت این فعالیت حیاتی از تأثیر آن بر تغذیه سلولها به عنوان کوچکترین واحد سازنده بدن انسان نشأت می گیرد، زیرا اکسیژن یکی از مواد ضروری برای سلولها می باشد و کسب این ماده حیاتی فقط از طریق تنفس مناسب و راحت امکان پذیر است .
