循環器系/心臓/心拍/cardiac cycle in English/ejection stage

- ポイント -

＊心室は収縮している．

＊心房内圧＜動脈圧＜心室内圧

＊房室弁は閉じている．

＊動脈弁は開いている．

＊心室→動脈の血流がある．

- ejection stage -

During the ejection stage,

• the ventricle is contracting.

• the pressure in the ventricle is higher compared to the pressure in the atrium.

• the atrio-ventricular valve is closed．

• the pressure in the ventricle is higher compared to the pressure in the artery.

• the arterial valve is open. *there is blood flow from the ventricle to the artery.
