So if you drink water will the total blood volume in the body change due to extra water enter the system?

Yes and No.: If you drink a lot of water you will absorb this through your gut and into the blood stream. Your kidneys will then regulate the solute balance and blood volume by excreting the excess as urine. Transiently there will be a slight increase in circulating volume and then the regulatory mechanisms will restore you to a normal balance. Clinically it is unlikely you would appreciate the transient.
