之间的区别耳膜and Ventricle

关键差异 - 耳廓vs Ventricle

循环是生物体的重要方面。存在circulatory systemin living organisms ensures the transportation of essential elements throughout the body. The human circulatory system possesses aheart作为抽水装置。心脏由四个腔室，两个上腔（左右心脏或耳廓）和两个下腔组成(left and right ventricles）。人心脏涉及维持两种类型的循环机制。肺循环和全身循环。这关键区别在耳膜和心室之间耳膜is located in the upper part of the heart while Ventricle is located in the lower part of the heart.

什么是耳膜？

输入血液的心脏上室被称为耳廓或atrium。这human heart possesses two atria, left atrium and right atrium. The two atria are separated into the left atrium and right atrium by a muscular wall at the medial edge of the right atrium. This is referred as an interatrial septum. This separation prevents the mixing ofatrium blood在两个心房之间。左心房从肺部收到血液，而右心房则从静脉循环中收到血液。换句话说，肺向左右提供含氧血液肺静脉。该血液通过二尖瓣泵入左心室，然后通过主动脉泵出最终的主动脉。

右心房从高级腔静脉和下腔静脉and direct it down to the right ventricle through the tricuspid valve which afterward is sent out from the heart through the pulmonary artery for pulmonary circulation. The basic function of the atria is to receive oxygenated blood from the lungs and provide it for systemic circulation and to receive deoxygenated blood and direct it for oxygenation through the pulmonary circulation. The atria don’t possess any inlet valves. They only possess双刺和三尖瓣which connect the左右心室分别。

中庭具有节点。这Sinoatrial (SA) node位于后心房w的地区hich is closer to the superior vena cava. The SA node consists of a group of cells known as pacemaker cells. These cells cause spontaneous depolarization which results in the generation of an action potential. The resulted cardiac action potential spreads across both left and right atria which stimulates the contraction. This contraction results in the pumping of blood into the ventricles through the valves. The自主神经系统通过SA节点将心脏连接到大脑，并用氧气和二氧化碳稳态来调节血压。另一种称为的节点心房（AV）节点is present between the atria and ventricles.

什么是心室？

心脏的下腔是心室。与耳廓类似，心室有两种类型，左心室和右心室。左室和右心室的大小相等。与右心室相比，左心室更长，为心脏提供圆锥形。左心室的壁比右心室的壁厚，以承受压力，因为它涉及在整个体内泵送血液。右心室的壁向心房更薄，但朝向心室的底部较厚，因为它仅将血液泵入肺部。两个心室壁比心房壁厚。

心室的内壁由不规则布置的肌肉柱组成trabeculae carneae。这se muscular columns consist of three types of different muscles. Out of the three muscles chordae tendinae is important since it attaches the cusps of the tricuspid valve and to the mitral valve. The interventricular septum divides the right ventricle from the left ventricle. During收缩和舒张the ventricles contract, and they pump blood throughout the body and relaxes to refill blood respectively.

左心房通过二尖瓣向左心室提供含氧血液。收到后，左心室在主动脉瓣的帮助下通过主动脉将血液泵入系统性循环。在此过程中，左心室肌肉接触并快速放松。这是由神经系统。右心房通过三尖瓣向右心室提供脱氧的血液。接收的血液通过肺动脉瓣通过肺动脉进行肺循环。

What is the Similarity Between Auricle and Ventricle?

• 两者都参与肺部和全身血液循环。

What is the Difference Between Auricle and Ventricle?

耳膜与心室
这auricles or atria are the upper chambers of the heart which is classified into left and right atria.	这lower chambers the heart are ventricles which consist of left and right ventricles.
Function
Aurreact通过上腔静脉和下腔静脉从全身循环中接收脱氧血液，并通过三尖瓣向右心室进行，然后通过三尖瓣向右心室进行，然后通过肺动脉从心脏中散发出肺循环。	心室通过左心房通过二尖瓣接收含氧血液，然后通过主动脉将其泵入系统循环。
室墙
耳膜s have thinner walls.	心室具有相对较厚的壁以承受压力。

Summary – Auriclevs Ventricle

这human heart is composed of four chambers, two upper chambers, and two lower chambers. The upper chambers are atria and lower chambers are ventricles. The human heart involves in maintaining two types of circulatory mechanisms; pulmonary circulation and systemic circulation. The right atrium receives deoxygenated blood from the systemic circulation and provides it to the right ventricle for pulmonary circulation whilst the left atrium receives oxygenated blood from the lungs and direct to left ventricle for systemic circulation.The ventricles have thicker walls than atria.This is the difference between atrium and ventricle.
