1.人体的八大系统分别用英语怎么说

运动系统locomotor system、神经系统nervous system、内分泌系统hormonal system、循环系统circulatory system、呼吸系统respiratory system、消化系统digestive system、泌尿系统urinary system、生殖系统reproductive system。

一、运动系统由骨、关节和肌肉组成，约占成人体重的60%。全身各骨借关节相连形成骨骼，起支持体重、保护内脏和维持人体基本形态的作用。

骨骼肌附着于骨，在神经系统支配下收缩和舒张，收缩时，以关节为支点牵引骨改变位置，产生运动。骨和关节是运动系统的被动部分，骨骼肌是运动系统的主动部分。

It consists of bones, joints and muscles, accounting for about 60% of adult body weight. Bones and joints of the whole body are connected to form bones, which can support weight, protect viscera and maintain the basic shape of the human body.Skeletal muscle adheres to bone, contracting and relaxing under the control of nervous system. When contracting, the joint is used as the fulcrum to pull the bone to change its position and produce movement. Bone and joint are the passive parts of the motor system, while skeletal muscle is the active part of the motor system.二、神经系统神经系统是人体内起主导作用的系统。内、外环境的各种信息，由感受器接受后，通过周围神经传递到脑和脊髓的各级中枢进行整合，再经周围神经控制和调节机体各系统器官的活动，以维持机体与内、外界环境的相对平衡。

神经系统是由脑、脊髓、脑神经、脊神经、和植物性神经，以及各种神经节组成。能协调体内各器官、各系统的活动，使之成为完整的一体，并与外界环境发生相互作用。

The nervous system is the dominant system in the human body. All kinds of information in the internal and external environment are received by the receptor, integrated through the peripheral nerve to all levels of the brain and spinal cord.and then controlled and regulated by the peripheral nerve to maintain the relative balance between the body and the internal and external environment.The nervous system is composed of brain, spinal cord, brain nerve, spinal nerve, vegetative nerve and various ganglia. It can coordinate the activities of organs and systems in the body, make them a whole body, and interact with the external environment.三、内分泌系统内分泌腺是人体内一些无输出导管的腺体。它的分泌物称激素。

对整个机体的生长、发育、代谢和生殖起着调节作用。人体主要的内分泌腺有：下丘脑、垂体、甲状腺、肾上腺、胰岛、胸腺和性腺等。

Endocrine glands are some glands without output ducts in human body. Its secretion is called hormone. It regulates the growth, development, metabolism and reproduction of the whole body.The main endocrine glands are hypothalamus, pituitary, thyroid, adrenal, islet, thymus and gonad.四、循环系统血液循环系统是生物体的体液（包括细胞内液、血浆、淋巴和组织液）及其借以循环流动的管道组成的系统。从动物形成心脏以后血液循环系统分为心脏和血管两大部分，叫做心血管系统。

循环系统是生物体内的运输系统，它将消化道吸收的营养物质和由鳃或肺吸进的氧输送到各组织器官并将各组织器官的代谢产物通过同样的途径输入血液，经肺、肾排出体外。The blood circulation system is a system of body fluids (including intracellular fluids, plasma, lymph and tissue fluids) and the pipes through which they circulate. The blood circulation system is divided into two parts, the heart and the blood vessel, which is called the cardiovascular system. Circulation system is the transportation system in organisms. It transports nutrients absorbed by digestive tract and oxygen absorbed by gill or lung to various tissues and organs, and transfuses metabolites of various tissues and organs into blood through the same way, and discharges them through lung and kidney.五、呼吸系统呼吸系统包括呼吸道（鼻腔、咽、喉、气管、支气管）和肺。

动物体在新陈代谢过程中要不断消耗氧气，产生二氧化碳。机体与外界环境进行气体交换的过程称为呼吸。

气体交换地有两处，一处是由外界与呼吸器官（如肺、腮）的气体交换，称肺呼吸或腮呼吸（或外呼吸）；另一处由血液和组织液与机体组织、细胞之间进行气体交换（称内呼吸）。The respiratory system includes the respiratory tract (nasal cavity, pharynx, larynx, trachea, bronchus) and lungs.Animals need to consume oxygen and produce carbon dioxide in the process of metabolism. The process of gas exchange between organism and environment is called breathing. There are two places for gas exchange, one is the exchange of gas between the outside and respiratory organs (such as lung and parotid), called pulmonary or parotid breathing (or external breathing). the other is the exchange of gas between blood and tissue fluid and organism tissues and 。
