血液流过心脏的路径动画演示

The Pathway of Blood Flow Through the Heart Animated Tutorial.

血液通过心脏流动的途径
The pathway of blood flow through the heart.
缺氧血从你的身体返回 至心脏的右心房
Oxygen-poor blood from your body returns to the right atrium of the heart.
上半身的血液通过上腔静脉返回
Blood from upper body returns through superior vena cava,
下半身的血液通过
blood from lower body returns through
下腔静脉返回
inferior vena cava.
由于右心房充满 血液
As the right atrium is filled with blood,
它收缩时
it contracts, the tricuspid valve opens and
三尖瓣打开血液被泵入右心室
blood is pumped into the right ventricle ofyour heart.
当右心室充盈后
When the right ventricle is full,
三尖瓣关闭 以防止
the tricuspid valve closes to prevent blood from flowing
血液流回心房
back into the atrium.
右心室收缩
The right ventricle contracts,
肺动脉瓣打开 血液被泵入肺动脉
pulmonary valve opens and blood is pumped into the pulmonary
动脉和你的肺
artery and to your lungs.
肺动脉瓣 关闭以防止血液倒流
Pulmonary valve closes to prevent blood from flowing back into the ventricle.
入右心室 富含氧气的血液从肺部返回到心脏的左心房由于左
Oxygen-rich blood from the lungs returns to the left atrium of the heart.
心房充满了血液
As the left atrium is filled with blood,
它收缩时 二尖瓣打开
it contracts, the mitral valve opens and blood
血液被泵 到你的心脏的左心室
is pumped into the left ventricle of yourheart.
同时
This occurs at the same time
在你心脏的另一侧 右心房将血液
as the right atrium pumps blood into the right ventricle
泵到在右心室
on the other side of the heart.
左心室充满后 二尖瓣关闭
As the left ventricle is full, the mitral valve closes,
左心室收缩
the aortic valve opens, the
主动脉瓣打开 富含氧气的血液
left ventricle contracts and oxygen-rich blood is pumped
泵入主动脉到达你
into the aorta to reach all parts
的身体的各个部位
of your body.
与此同时
This happens at the same time
在心脏的另一侧 相同的情况也在发生 即右心室将血液泵入肺动脉
as the right ventricle pumps blood into the pulmonary artery
(心室舒张时 )
on the other side of the heart.
主动脉瓣迅速关闭以防止血液倒流 入心脏
The aortic valve quickly closes to prevent blood from flowing back to the heart. Meanwhile,
同时 心房被血液充满 如此循环往复
the atria have filled with blood and the cycle repeats itself.
