他的心脏已经分成了四个腔室，瓣膜也开始形成了。
His heart has divided into four Chambers and its valves are beginning to form.
心脏也有四个腔室，也是红的。
非常有趣的是，发育中的哺乳动物晶胚的心脏在分化为四腔室前，与斑马鱼的双腔心脏非常相似。
Intriguingly, before the heart of a developing mammalian embryo separates into four Chambers, it looks similar to the two-chambered zebrafish heart.
当心脏收缩的时候，腔室会变小，首先迫使血液从心房出来进入心室，然后从每个心室进入一个连在心脏上方的大血管。
When the heart contracts, the chambers become smaller, forcing blood first out of the atria into the ventricles, then from each ventricle into a large blood vessel connected to the top of the heart.
方法：利用彩色多普勒超声心动图检测68例先天性房间隔缺损患儿与82例正常新生儿心脏各腔室的大小、肺动脉内压力、三尖瓣反流等。
Methods:Investigated all chambers of the heart ; pulmonary artery pressure and tricuspid regurgitation in 68 congenital antrum septal defect and 82 normal neonates by colour Doppler echocardiography.
心脏有不同的腔室，他们之间有门连接。
特别地，心脏的每个腔室可以被映射成具有2d和3d的精确的维度和位置追踪信息的有限元模型。
Specifically, each chamber of the heart can be mapped into finite element model with accurate dimension and position tracking information, both 2d and 3d.
心脏重构是指发生于心肌损伤之后的分子和细胞事件所导致的心脏各腔室形态、内径和功能改变。
Cardiac remodeling is defined as an alteration in anatomy, inter diameter and function of cardiac Chambers caused by a series of molecular and cellular events after injury to the heart.
