A healthy adult has 5 Liters of circulating blood and another 500 ml as reserve in the spleen. Loss of up-to 500 ml of blood will not usually produce any tachycardia or hypo-tension unless fear of blood loss occurs in an otherwise healthy person.
This is entirely dependant on the individual. Some may experience shock at 500ml loss, while others around 1000ml lost.

Shock is the medical term given to when a patient has lost a large amount of blood (hypovolaemia).
A rapid and large decrease in blood volume affects blood pressure and produces shock. Along with the precipitous drop in blood volume from blood loss, there is a drop of RBC that carry O2. Shock is a life-threatening condition.Note: This medical term does not mean a psychological or emotional "shock", or an electrical "shock".
Not necessarily. Your body will try to compensate when it is in shock by raising the heartbeat (thereby increasing blood pressure). But sometimes the body can not compensate adequately. In this case, your blood pressure may not increase.
