What would happen if you lost 2 pints of blood?

hypovolemic shock
can occur. Hypovolemic shock is a medical emergency in which severe blood and fluid loss impedes the heart to pump sufficient blood to the body. As a result, tissues cannot get enough oxygen, leading to tissue and organ damage.
What percentage of blood loss is considered a life threatening situation?
Hypovolemic shock is a life-threatening condition that results when you lose
more than 20 percent (one-fifth)
of your body's blood or fluid supply. This severe fluid loss makes it impossible for the heart to pump a sufficient amount of blood to your body.

How does the body compensate for blood loss?
