The human body responds to this shock by activating the following physiologic systems. The hematologic system responds to severe blood loss by contracting the bleeding vessels. This system also activates platelets and start to form clots on the bleeding source. The clot takes a 24 hours to complete into full formation. The cardiovascular system begins to respond to hypovolemic shock by increasing the heart rate and constricting peripheral blood vessels. The cardiovascular system also responds by redistributing blood to the heart, brain and kidneys and keeping blood away from the skin, muscle and GI tract. The renal system responds to the shock by increasing renin secretion from the juxtaglomerular apparatus. The neuroendocrine system responds hypovolemic shock by stimulating an increase in ADH. ADH is released in correspondence to low blood pressure and decrease in sodium concentration. The symptoms previous to hypovolemic shock include confusion and weakness. Sweaty or clammy skin along with rapid breathing and pallor are also symptoms. Unconsciousness can occur as well.
