Becau it contains living cells, blood is alive. Red blood cells and white blood cells are responsible for nourishing and cleansing the body. Since the cells are alive, they too need nourishment. Vitamins and Minerals keep the blood healthy. The blood cells have a definite life cycle, just as all living organisms do.
因为它含有活细胞,⾎液是活的,有⽣命的。红细胞和⽩⾎球负责滋养和清洁⾝体。既然细胞是有⽣命的,它们也需要营养。维⽣素和矿物质保持⾎液健康。⾎细胞有⼀定的的⽣命周期,就像所有⽣物体⼀样。
About 55 percent of blood is plasma , a straw-colored clear liquid. The liquid plasma carries the solid cells and the platelets , which help blood clot. Without blood platelets, you would bleed to death.
⾎浆约占⾎液重量的55%,是淡黄⾊透明液体。液体⾎浆携带着固体细胞和⾎⼩板,⾎⼩板有助于⾎液凝固。没有⾎⼩板,你会流⾎致死。

When the human body los a little bit of blood through a minor wound, the platelets cau the blood to clot so that the bleeding stops. Becau new blood is always being made inside of your bones, the body can replace the lost blood. When the human body los a lot of blood through a major wound, that blood has to be replaced through a blood transfusion from other people.
当⼈体通过⼀个⼩伤⼝失去⼀点点⾎时,⾎⼩板会使⾎液凝结,⾎流停⽌。因为新⾎总是在你的⾻头⾥⾯制造,⾝体可以补充丢失的⾎液。当⼈体由于伤⼝过⼤失去⼤量⾎液时,必须通过输来⾃其他⼈的⾎来补充⾎液。
But everybody's blood is not the same. There are four different blood types. Plus, your blood has Rh factors, which make it even more unique. Blood received through a transfusion must match相配 your own.

coagulation [kəʊˌæɡjuˈleɪʃn] n. 凝结,凝结物;
The blood cells have each of their own different life spans as well as individual functions. Among the three, the platelets are the smallest but one of the most important factors in blood clotting. If blood platelets don’t regulate properly, such as inability to renew adequately at normal intervals, then blood dysfunction or disorder can occur.
⾎细胞有各⾃不同的寿命以及各⾃的功能。在这三者中,⾎⼩板最⼩,但是⾎液凝固中最重要因素之⼀。如果⾎⼩板不能正常调节,例如不能保持正常值的充分更新,则可能发⽣⾎液功能障碍或失调。

The general lifespan of a platelet is about 10 days. The normal platelet count in the human blood ranges from 150,000 to 450,000 per micro liter of blood. The exact amount of platelet count will vary among the different body parts and organs.
⾎⼩板的寿命通常约为10天。⼈体⾎液中的正常⾎⼩板计数在每微升⾎液15万到45万之间。⾎⼩板的确切数量在不同的⾝体部位和器官中会有所不同。

This makes it an utmost importance to maintain and ensure proper management and diet that favors a person with
low platelet count.
实际上,⾎⼩板数量下降背后有⼏个原因。⾎⼩板减少症也可以作为⼀种催化剂,触发体内其他潜在的疾病。⾎⼩板计数低表明存在出⾎风险,需要⽴即就医。维持和确保适当的管理和饮⾷对⾎⼩板计数较低的⼈最为重要。

It is widely known that the popular pain killers people are ud to can be harmful to the body. It may help achieve ea of pain for the time being, but in the long run, excessive u can cau certain factors of the blood to be acutely altered. Pain killers contain substances with a capacity to directly create a damaging effect on blood components and various other organs, especially if not monitored carefully. The composition of the blood may possibly also change to an imbalanced state due to the effects of chemical substances. With prolonged intake of pain relievers, it doesn’t just affect platelets but can even lead to organ failure in some individuals.
众所周知,⼈们常⽤的⽌痛药对⾝体有害。它可能暂时有助于减轻疼痛,但从长远来看,过度使⽤会导致某些⾎液因素发⽣剧烈改变。⽌痛药含有的物质能够直接对⾎液成分和各种其他器官造成损害,尤其是如果不仔细监测的话。由于化学物质的影响,⾎液的成分也可能改变为不平衡状态。长期服⽤⽌痛药不仅会影响⾎⼩板,甚⾄会导致某些⼈的器官衰竭。
