血液也是由许多细胞组成 在我们身体需要血液不断流动的细胞内在身体周围运

Blood is also composed of many cells, which are transported around the body in the cells that need blood to flow continuously. In this process, cells produce energy from glucose. Glucose breaks down into carbon dioxide and water. This requires oxygen and carbon dioxide to be processed, so the blood must supply oxygen and take carbon dioxide away.

Blood is also composed of many cells, which are transported inside and around our body. In this process, cells produce energy from glucose. Glucose breaks down into carbon dioxide and water. This needs to consume oxygen and carbon dioxide to be processed, so the blood must supply oxygen and take away carbon dioxide.<br>

Blood is also composed of many cells, which are transported around the body in the cells of our body that need constant blood flow. In this process, cells produce energy from glucose. Glucose is broken down into carbon dioxide and water. This needs to consume oxygen and carbon dioxide to be treated, so blood must supply oxygen and take away carbon dioxide.
