英语翻译
The body’s many hormones are messenger molecules,and some hormones are proteins.♦ Various endocrine glands in the body release hormones in response to changes that challenge the body.The blood carries the hormones from these glands to their target tissues,where they elicit the appropriate responses to restore and maintain normal conditions.
The hormone insulin provides a familiar example.After a meal,when blood glucose rises,the pancreas releases its insulin.Insulin stimulates the transport proteins of the muscles and adipose tissue to pump glucose into the cells faster than it can leak out.After acting on the message,the cells destroy the insulin.As blood glucose falls,the pancreas slows its release of insulin.Many other proteins act as hormones,regulating a variety of actions in the body (see Table 6-2 for examples).As Regulators of Fluid Balance Proteins help to maintain the body’s fluid balance.Normally,proteins are found primarily within the cells and in the plasma (essentially blood without its red blood cells).Being large,proteins do not normally cross the walls of the blood vessels.During times of critical illness or protein malnutrition,however,plasma proteins leak out of the blood vessels into the tissues (between the cells).Because proteins attract water,fluid accumulates and causes swelling.Swelling due to an excess of fluid in the tissues is known as edema.The protein-related causes of edema include.

♦ Various endocrine glands in the body release hormones in response to changes that challenge the body.在外界刺激下,人体中很多内分泌腺体都释放荷尔蒙来做出反应.The blood carries the hormones from these glands to their target tissues,where they elicit the appropriate responses to restore and maintain normal conditions.血液把荷尔蒙从这些腺体输送到目标组织中,从而引出这些组织做出合适的反应来恢复或保持其正常状态.
The hormone insulin provides a familiar example.拿胰岛素举例来说.After a meal,when blood glucose rises,the pancreas releases its insulin.吃完饭后,血液中的葡萄糖浓度升高,胰腺分泌胰岛素Insulin stimulates the transport proteins of the muscles and adipose tissue to pump glucose into the cells faster than it can leak out.胰岛素刺激肌肉和脂肪组织中的传输蛋白,蛋白把葡萄糖泵如细胞,葡萄糖进入细胞的速度大于渗出的速度.After acting on the message,the cells destroy the insulin.在对这个信息反应后,细胞便销毁胰岛素.As blood glucose falls,the pancreas slows its release of insulin.随着血液中葡萄糖的下降,胰腺降低分泌胰岛素的速度Many other proteins act as hormones,regulating a variety of actions in the body (see Table 6-2 for examples).很多其他蛋白作为荷尔蒙,调节大量人体中大量的反应（见表6-2）As Regulators of Fluid Balance Proteins help to maintain the body’s fluid balance.作为血液流体调节器,Normally,proteins are found primarily within the cells and in the plasma (essentially blood without its red blood cells).通常情况下,蛋白主要存在细胞和血清（没有红细胞的血液）中存在,Being large,proteins do not normally cross the walls of the blood vessels.因为体积比较大,蛋白通常不能穿透血管壁 During times of critical illness or protein malnutrition,however,plasma proteins leak out of the blood vessels into the tissues (between the cells).然而,在严重病变或蛋白营养不良的时间里,血清蛋白会透过血管壁渗透到组织中.Because proteins attract water,fluid accumulates and causes swelling.由于蛋白的吸水性,液体会聚集并引起肿胀.Swelling due to an excess of fluid in the tissues is known as edema.过多液体引起的肿胀就是水肿,The protein-related causes of edema include.
