About 83% of blood is water.
Water
The Large Intestine
The small and large intestine (water in the large and vitamins and minerals in the small), which is part of the digestive system.
Filtration of blood occurs in the glomerulus, which is the initial part of the renal tubule where blood is filtered to form a fluid called glomerular filtrate. This process is responsible for removing waste products, excess ions, and water from the blood to form urine.
The nephron is the part of the kidney that produces urine.
The part of the blood cell that carries water around the body are the plasma cells
Water that you drink, like all nutrients, enters the blood in the digestive tract. Water is different for example from proteins and fats in that it gets absorbed throughout the digestive tract and not only in a particular part such as the stomach or a part of the intestines. The major site of water readsorption from the intestines however is the large intestine (colon). Here, the removal of water and uptake into the blood contributes towards drying and concentrating the stool.
The blood Plasma

Inferior vena cava.
Blood is what a chemist would describe as an aqueous solution; the liquid part is simply water.
