Metabolism is a combination of biochemical processes that your body uses to convert food into energy. These metabolic processes include breathing, eating and digesting food, the delivery of nutrients to your cells through the blood, the use of energy by your muscles, nerves and cells, and finally the elimination of waste products from your body. 新陈代谢是你的身体把食物转换成能量的生物与化学结合的过程。那些代谢过程包括呼吸、进食和消化食物,从血液到细胞的营养物质运送,肌肉，神经和细胞所需能量的使用,还有最后身体废物的排出。 |
