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: -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.

Detailed explanation-3: -The most numerous cation in blood plasma is Na+, K+, Mg+, and Ca2+. However, Na+ is the main cation and is responsible for the plasma osmolarity.

Detailed explanation-4: -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. Over 99% of the solid particles in blood are cells known as red blood cells (erythrocytes) due to their red color.

Detailed explanation-5: -What percentage of blood is plasma? Plasma makes up 55% of your blood’s total volume. Red blood cells follow at 44% of your blood’s volume, and a combination of white blood cells and platelets fill the remaining 1%.
