Detailed explanation-1: -Serum albumin, another protein synthesized by the liver, constitutes approximately 60 percent of all of the plasma proteins. It is very important in maintaining osmotic pressure in the blood vessels; it is also an important carrier protein for a number of substances, including hormones.

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 origin of plasma, which constitutes 55% of total blood, is interesting because no organ produces it. Instead, it is formed from water and salts absorbed through the digestive tract.

Detailed explanation-4: -The components that add volume to blood include red blood cells (erythrocytes), white blood cells (leukocytes), platelets, and plasma. Plasma accounts for about 60% of total blood volume, while erythrocytes make up roughly 40%, along with leukocytes and platelets.

Detailed explanation-5: -Plasma is a key element of blood (55% of the total blood volume). Plasma is the clear straw-coloured liquid portion of blood that remains after red blood cells, white blood cells, platelets and other cellular components have been removed. Plasma carries water, salts, and proteins through the body.
