plasma
Blood plasma is the liquid component of blood, in which the blood cells are suspended. Plasma is a yellow colored liquid. Plasma is the largest single component of blood, making up about 55% of total blood volume.

Composition of the blood:
Plasma: approx 55% of the volume of blood. Contains approx 90% water, salts carried as ions, and large plasma proteins. It also transports hormones, waste materials like carbon dioxide and urea and products of digestion like amino acids and sugars. Red and white blood cells are suspended in the plasma.
Red Blood Cells (Erythrocytes): disc-shaped and biconcave; no nucleus. Contain the pigment Haemoglobin, and transport respiratory gases.
White blood cells (Leucocytes): have many types, but are usually larger than red blood cells. All have a nucleus. Production of cells increase when a person is sick to fight the infection.
Platelets: fragments of cells made in bone marrow. Very small and help the blood to clot.

There are four major types of blood cells: red blood cells, platelets, lymphocytes, and phagocyte cells. Collectively, the lymphocytes and phagocyte cells constitute the white blood cells. Each type of blood cell has a specialized function: red cells take up oxygen from the lungs and deliver it to the tissues; platelets participate in forming blood clots; lymphocytes are involved with immunity; and phagocyte cells occur in two varieties-granulocytes and monocytes- and ingest and break down microorganisms and foreign particles. The circulating blood functions as a carrier, bringing the various kinds of cells to the regions of the body in which they are needed: red cells to tissues requiring oxygen, platelets to seal over points of injury, lymphocytes to areas of infection, and phagocyte cells to sites of microbial invasion and inflammation.

Yeah, what Candy said- water.
Hey, do you remember that one episode of Star Trek NG- with the crystaline entity?.... They seeded a second one on the ship, and it called all the humanoids "ugly bags of mostly water".... yeah, that's the one...
