神经和血管之间的差异

关键区别 - 神经vs Blood Vessels

这nervous systemand the循环系统are two vital organ systems in our body. The nervous system is responsible for transmission of electrochemical signals or the nerve impulses while the circulatory system is responsible for the transportation of the blood mixed with oxygen, carbon dioxide, nutrients, hormones and wastes throughout the body. Nerves or the神经元are the basic functional units of the nervous system. Nerves are specialized cells which receive, processes and transmit information from the body to brain and back to the body. Blood vessels are one component among the three main components of the circulatory system. Blood vessels deliver blood to and from the heart to and from the rest of the body. Blood vessels make a network of closed tubes to carry blood within the body. There are three main types of blood vessels namely,arteries,capillaries, and veins。这key difference在神经和血管之间，nerves transmit electrochemical signals whereas blood vessels transport blood throughout the body.

什么是神经？

A neuron is the basic functional unit of our nervous system which carries nerve impulses. Neurons are specialized nerve cells which receive, processes and transmit information from the body to brain and back to the body. There are 10 to 100 billion neurons in our nervous system. Neurons do not regenerate. Approximately 10000 neurons die daily from our body. The nerve is composed of three main components; cell body,dendrites and axon。树突接收来自其他神经元的消息，并通过细胞体传递到轴突。轴突将电信号转换为化学信号，并通过突触使用称为的化学信使neurotransmitters。Dendrites of the subsequent neuron convert chemical signal again into an electrical signal and pass along its axon to terminal buttons. Likewise, information are transmitted through neurons throughout the body into target organs, glands, muscles and into other neurons.

有三种类型的神经。sensory nerves, motor nerves和继电器神经。感觉神经从感觉器官到达电化学信号central nervous system。继电器神经从中枢神经系统的一部分传递到另一部分的信号。运动神经带有来自中枢神经系统到效应器官的信号。大多数神经得到Schwann细胞。Schwann细胞通过产生一种称为髓磷脂的脂肪物质并缠绕在轴突周围，从而提高了沿神经细胞的神经脉冲传播的效率。

What are Blood Vessels?

循环系统是我们的主要器官系统之一，它在整个人体中运输血液，气体，激素，营养素。心，血液和血管是人类的主要元素心血管系统，这是一个封闭的系统，在该系统中，血液仅在管子网络中循环，称为血管。血管将血液传给心脏，最终到身体的所有部位。血管有三种主要类型；动脉，毛细血管和静脉。动脉将血液从心脏传给其他人tissuesof the body. Capillaries are the tiny blood vessels which facilitate the exchange of oxygen, nutrients, and wastes between the blood and the tissues. Veins carry oxygen-depleted blood from the body tissues to the heart.

动脉和静脉由三个称为Tunica Intima，Tunica Media和Tunica Adventitia的细胞层组成。由于动脉中存在的高血压，动脉的壁比静脉壁厚。静脉的直径比动脉更大。

What are the Similarities Between Nerves and Blood Vessels?

• Both blood vessels and nerves are long and thin.
• 两者都执行运输功能。
• 两者都是体内的重要通道。
• 神经和血管都位于整个身体。
• 神经and blood vessels travel together in almost all tissues in the body.
• 两者都是高度分支的结构。

What is the Difference Between Nerves and Blood Vessels?

神经与血管
神经是专门的细胞，将信息作为整个人体的电信号携带，并且是神经系统的基本功能单位。	Blood vessels are the tube-like structures of the circulatory system which transports oxygenated and deoxygenated blood from and to heart.
Structure
神经are single cells composed of dendrites, cell body, and axons	血管是由许多小细胞层组成的管状结构。
类型
神经are main three types; sensory nerves, relay nerves, and motor nerves.	Blood vessels are three types; arteries, capillaries or veins
功能
神经在整个身体中移动电化学信号。	血管在整个身体中移动血液。
Main Organ System
神经是神经系统的基本功能单位。	Blood vessels are elements of circulatory or the cardiovascular system.
Connection with Body Organs
神经连接到大脑和脊髓。	Blood vessels are connected with the heart.
封闭或打开
神经are not closed or touch with each other.	血管制造了一个封闭的系统。

摘要 - 神经vs Blood Vessels

神经or neurons are specialized cells which transmit signals throughout the body. They are the basic functional units of the nervous system. Blood vessels are the valves which deliver blood throughout the body. Blood vessels and nerves run together in all the tissues in our body. Nerves deliver electrochemical signals while blood vessels deliver blood mixed with nutrients, hormones, gasses, and wastes. This is the difference between nerves and blood vessels.
