僧帽辨是哪個(gè)辨膜的稱(chēng)號

僧帽辨是哪個(gè)辨膜的稱(chēng)號：二尖瓣。

二尖瓣介紹如下：

二尖瓣（mitral valve）即左房室瓣。附于左纖維房室環(huán)上，系由心內膜的皺褶形成。有兩個(gè)瓣膜，位于前內側者為前尖瓣，較大，常稱(chēng)大瓣，是左心室流入道與流出道的分界標志;位于后外側者為后尖瓣，較小，常稱(chēng)小瓣。瓣膜呈三角形，尖朝向左室腔。

兩個(gè)瓣膜底部邊緣常相互融合，有時(shí)在兩瓣間出現小的副瓣。瓣尖、邊緣及其室面有許多腱索連于乳頭肌。心室收縮時(shí)，二尖瓣即嚴密關(guān)閉房室口，防止血液逆流入左心房。

二尖瓣的定義介紹如下：

心臟左心房構成心底的大部分，有四個(gè)入口，一個(gè)出口。在左心房后壁的兩側，各有一對肺靜脈口，為左右肺靜脈的入口；左心房的前下有左房室口，通向左心室。左心房前部向右前突出的部分，稱(chēng)左心耳。左心室有出入二口。

入口即左房室口，周緣附有左房室瓣（二尖瓣），按位置稱(chēng)前瓣、后瓣，它們亦有腱索分別與前、后乳頭肌相連。出口為主動(dòng)脈口，位于左房室口的右前上方，周緣附有半月形的主動(dòng)脈瓣。

二尖瓣的解釋介紹如下：

是附于左房室口周緣的二片瓣膜、借腱索連于乳頭肌，有阻止左心室的血液流回左心房的作用。在左心室有出入二口。入口即左房室口，周緣附有左房室瓣（二尖瓣）。

按位置稱(chēng)前瓣、后瓣，它們亦有腱索分別與前、后乳頭肌相連。出口為主動(dòng)脈口，位于左房室口的右前上方，周緣附有半月形的主動(dòng)脈瓣。

二尖瓣如同一個(gè)“單向活門(mén)”，保證血液循環(huán)由左心房一定向左心室方向流動(dòng)和通過(guò)一定流量。心臟當左心室收縮時(shí)，擠壓室內血液，血液沖擊瓣膜。

二尖瓣的介紹

二尖瓣（mitral valve）又叫僧帽瓣，其如同一個(gè)左房和左室之間的“單向活門(mén)”，保證血液循環(huán)由左心房一定向左心室方向流動(dòng)和通過(guò)一定的血流量。
