The ability of the body to perform under stress without undue fatigue, circulorespiratory endurance.  

Failure of the circulation, either cardiac or peripheral. Circulatory collapse is a critical condition characterized by the inability of the circulatory system to sustain a sufficient blood flow to the body’s organs and tissues. This life-threatening state can arise from cardiac arrest, significant blood loss, or issues affecting the blood vessels.
