按照心血管系统解剖、循环词汇的顺序，我们今天来学习心血管系统的医学英语词汇～
Cardiovascular anatomy 心血管系统解剖
Endocardium 心内膜
Endothelium is a group of cells which are same as blood vessels
Myocardium 心肌层
which is made by cardiac musle cell and connecive tissue
Epicardium 心内膜
Superior vena cava 上腔静脉
Inferior vena cava 下腔静脉
Coronary sinus 冠状窦 blood from coronary veins
Right atrium 右心房
Atrioventricular valve 房室瓣
Chordae tendineae 腱索
Papillary muscle 乳头肌
prevents regurgitation back into atrium防止血液回流
Pulmonary artery 肺动脉
Pulmonary valve 肺静脉
Atrioventricular valve 房室瓣
Chordae tendineae 腱索
Papillary muscle 乳头肌
prevents regurgitation back into atrium 防止血液回流
Aortic valve 主动脉瓣
Aorta 主动脉
Arterioles 小动脉
Capillaries 毛细血管
Tunica intima 血管内膜 Tunica intima (the thinnest layer): a single layer of simple squamous endothelial cells.
Tunica media 血管中膜 Smooth muscle cells and elastin
Tunica externa 血管外膜 It is mainly composed of collagen and, in arteries, is supported by external elastic lamina
Arteriole 小动脉
Bulky muscles 内弹性膜
Contracts 收缩
Relaxes 舒张
Thermoregulation 体温调节
Capillary 毛细血管
connect arterioles and venules, and they help to enable the exchange of water, oxygen, carbon dioxide, and many other nutrients and waste substances
连接小动脉和小静脉，它们有助于交换水，氧气，二氧化碳和许多其他营养物质和废物
Circuitry of the cardiovascular system 心血管系统循环
Cardiac output of the left heart = cardiac output of the right heart.
Cardiac output from the left side of the heart is the systemic blood flow. 心脏左侧的心输出量是全身血流量
Cardiac output from the right side of the heart is the pulmonary blood flow. 心脏右侧的心输出量是肺血流量
Direction of blood flow
Blood flows along the following course:
1.From the lungs to the left atrium via the pulmonary vein血液通过肺静脉从肺流向左心房
2. From the left atrium to the left ventricle through the mitral valve血液通过二尖瓣从左心房流入左心室
3. From the left ventricle to the aorta through the aortic valve血液通过主动脉瓣从左心室流入主动脉
4.From the aorta to the systemic arteries and the systemic tissues 血液从左心室流向全身
5. From the tissues to the systemic veins and vena cava 从组织流向腔静脉
6. From the vena cava (mixed venous blood) to the right atrium 从腔静脉流向右心房
7. From the right atrium to the right ventricle through the tricuspid valve 从右心房流向右心室
8. From the right ventricle to the pulmonary artery through the pulmonic valve 从右心室流向肺动脉
9. From the pulmonary artery to the lungs for oxygenation 肺动脉经肺进行氧气交换
重点词汇
superior vena cava 上腔静脉
inferior vena cava 下腔静脉
right atrium 右心房
tricuspid valve 三尖瓣
right ventricle 右心室
pulmonary valve 肺静脉瓣
pulmonary artery 肺动脉
pulmonary veins 肺静脉
left atrium 左心房
mitral valve 二尖瓣
left ventricle 左心房
