okay, so Shock is a rapid loss in blood pressure, meaning the body is less able to pump oxygen (via blood in arteries) to all it's necessary organs.

Hypovolemic shock is particularly where the blood pressure loss is caused by rapid blood or fluid loss in the body. This may be caused by dehydration or internal/external bleeding. So basically the body's organs aren't receiving enough blood/oxygen.

The weak pulse is basically a physical indicator that the body has a low systolic blood pressure. Now, since the weak pulse provides less oxygen to the body, the body needs to come up with a logical way to push more oxygen into the body systems. The only way to do this would be to increase the heart rate so to even out the fact the blood pressure is low. Hence, you end up with a rapid but weak pulse.

Hope this Helps :)
