Why do you need blood in you body?
To transfer O2 to cells and CO2 away, to transfer nutrients, thermoregulation , transfer hormones from site of production to site where they're used...

I don't have a very bio brain.

I guess the glucose levels will fall ? Blood pressure will decrease, so heart rate will increase ?

Blood supplies nutrients to the body. If you bleed a lot then the supply is reduced. Essential organs are supplied but this will reduce leading to oxygen deprevation. Then cells start dying

I would have thought it's because if there is not enough blood, there is not enough oxygen getting to the organs and tissues in the body.

Because different parts of the body need the energy and oxygen that red blood cells and plasma provide, particularly the brain. This can be very detrimental to organs. (this is very rough btw, I haven't done biology in three years).
Think about the purpose of pumping blood around the body and why a lack of it would be bad.

Oxygen is transported to every cell requiring it by the blood -specifically important for brain function, and this regulates the function of everything else.
Blood can only travel via pressure, created by having a set blood volume - you can minimalise and increase pressure by other means biologically but only within small ranges. Without that blood volume pressure drops and no matter how hard and fast the heart contracts pressure remains low and your tissues begin to lose oxygen supply.

The spleen can contract - pumping a large increased reservoir of blood out, but once this is gone without a transfusion you are a goner.

Blood transports oxygen to cells. Cells need oxygen to respire. Respiration is an essential life process. That’s your three marker sorted
