Describe the effect of hypovolemic shock on the blood vessels and the heart.
What will be an ideal response?
Hypovolemic shock causes blood vessels to constrict to increase venous return and maintain pressure. Heart rate increases to compensate for loss of blood pressure and to maintain cardiac output. If volume loss continues, pressure eventually drops sharply and the shock becomes irreversible, leading to death.
