The urinary system maintains normal levels of water and of certain small molecules such as sodium and potassium in the body. It does this by passing blood through the kidneys, two efficient filtering organs that get rid of any excess of various molecules and conserve those molecules that are in short supply.

泌尿系统为人体维持水分和某些小分子物质,如纳和钾。它通过肾脏过滤血液来做到这一点。肾是两个有效的过滤器官,可以过滤掉各种多余的小分子,保留下来那些供应不足的小分子。

The fluid that leaves the kidneys, known as urine, travels through a tube called the ureter输尿管 to the bladder. The bladder holds the urine until it is voided from the body through another tube, the urethra尿道。

从肾脏流出的液体,即尿液,通过输尿管流至膀胱。膀胱贮存尿液,直至人体通过另一管道,即尿道,将它排空。

The nervous system------the brain, the spinal cord脊髓, and the nerves------also controls body activities. The lower parts of the brain control basic functions such as breathing and heart rate as well as body temperature, hunger, and thirst. Above these regions are the centers for sight, sound, touch, smell, and taste, and the regions that direct voluntary muscular activities of the arms and legs. Performed here are the higher functions of integrating and processing information.

神经系统——包括大脑,脊髓和神经,也在调控着机体活动。脑的偏下部位控制着人体的基本功能,如呼吸,心跳,体温和饥渴。而脑的偏上部位则是视觉,听觉,触觉,嗅觉和味觉中心,也是指挥臂、腿随意肌肉运动的区域。神经系统更高级的功能是整合、处理信息。

The brain receives and sends information by means of nerves, many of which lie partly in the spinal cord. The spinal cord is protected by the spinal column脊柱. Nerves enter and leave the spinal cord at each level of the body, traveling to and from the arms, legs and trunk. These nerves bring information from the various sense organs. The information is processed by the brain, and then messages are carried back to muscles and glands throughout the body.

大脑通过神经接受并发送信息,许多神经部分地分布于脊髓中。脊柱保护脊髓。在机体每一级,神经传入、传出脊髓,往返于臂、腿、及躯体。这些神经将各感官器官的信息传达给大脑来处理,然后再将大脑的反馈信息传送到全身和腺体。
