循環器系/心臓/心拍/cardiac cycle in English/tension (isometric contraction) stage
*心室は収縮して,血圧は上昇中.
*心房内圧<心室内圧<動脈圧
*房室弁は閉じている.
*動脈弁は閉じている.
*血流はない.
During the tension (isometric contraction) 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
- there isn't any blood flow from the atrium to the ventricle.
- the pressure in the ventricle is lower compared to the pressure in the artery.
- the arterial valve is closed.
- there isn't any blood flow from the ventricle to the artery.
