介绍:
31. Oxygen氧气
[00:01.86]Oxygen, that thing you breathe,
[00:05.00]that essential gas that keeps the world going round
[00:08.28]is really more important than you give it credit for.
[00:11.92]Oxygen is what essentially and literally
[00:15.62]keeps you alive and keeps you going.
[00:18.25]Consider this: people can survive for a few days
[00:22.60]without food and water,
[00:24.27]but do you think a person can survive
[00:26.60]even a few minutes without oxygen?
[00:29.33]No, the brain would die
[00:32.02]and the heart would stop pumping immediately.
[00:34.98]This is how essential oxygen is to the human body.
[00:39.14]It is used to convert fats and proteins
[00:42.39]from the food we consume into heat and energy
[00:46.08]for the body and its normal functioning.
[00:48.62]Oxygen is essential for the production of living cells
[00:52.87]and for respiration of these cells as well.
[00:55.83]Oxygen is also used in removing toxic waste from the body.
[01:00.85]Quite simply put, the more the oxygen there is in the body,
[01:05.89]the more energetic the body will be.
