Detailed explanation-1: -Plasma contains 91% to 92% of water and 8% to 9% of solids. It mainly comprises of: Coagulants, mainly fibrinogen, aid in blood clotting. Plasma proteins, such as albumin and globulin, that help maintain the colloidal osmotic pressure at about 25 mmHg.

Detailed explanation-2: -Over 90% of blood plasma is water, while less than 10% consists of dissolved substances, mostly proteins. Blood plasma also contains electrolytes, vitamins and nutrients such as glucose and amino acids.

Detailed explanation-3: -Plasma constitutes 55% of total blood volume. Composed of 90% water, salts, lipids and hormones, it is especially rich in proteins (including its main protein albumin), immunoglobulins, clotting factors and fibrinogen.

Detailed explanation-4: -Plasma is derived when all the blood cells-red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes)-are separated from whole blood. The remaining straw-coloured fluid is 90–92 percent water, but it contains critical solutes necessary for sustaining health and life.

Detailed explanation-5: -Plasma is about 92% water. It also contains 7% vital proteins such as albumin, gamma globulin and anti-hemophilic factor, and 1% mineral salts, sugars, fats, hormones and vitamins.
