Detailed explanation-1: -Plasma, also known as blood plasma, appears light-yellowish or straw-colored. It serves as the liquid base for whole blood. Whole blood minus erythrocytes (RBCs), leukocytes (WBCs), and thrombocytes (platelets) make up the plasma.

Detailed explanation-2: -Blood plasma is the yellow liquid component of blood, in which the blood cells in whole blood are normally suspended. The color of the plasma varies considerably from one sample to another from barely yellow to dark yellow and sometimes with a brown, orange or green tinge [Figure 1a] also.

Detailed explanation-3: -Nutrients absorbed from the gut or from other organs of origin are carried in the plasma, such as glucose, fats, amino acids, minerals, and vitamins. Plasma also contains dissolved oxygen and carbon dioxide, in small amounts, as well as a significant amount of nitrogen.

Detailed explanation-4: -Lymph is the clear, nearly colorless, alkaline fluid that occupies the space between all cells of the body. The term for this is ‘interstitial fluid’ (in ter STISH awl), and it is similar to blood plasma. It is 95% water. It seeps in and out through the walls of very small vessels called capillaries.

Detailed explanation-5: -Plasma is the largest single component of blood, and makes up about 55% of total blood volume. It is a clear, straw-coloured liquid, which carries platelets, red and white blood cells.
