Plasma, the liquid component of blood, is primarily composed of water, but it also contains many other substances. Here is a step-by-step breakdown of its composition:

1. Water: This is the most abundant component of plasma, making up about 90-92% of it. Water acts as a solvent, carrying other substances throughout the body.

2. Proteins: These make up about 7% of plasma. The three main types of plasma proteins are albumins, globulins, and fibrinogen. Albumins help maintain the body's osmotic balance, globulins play a role in the immune system, and fibrinogen is involved in blood clotting.

3. Salts and ions: These make up about 0.9% of plasma. They help maintain the body's pH balance and play a role in many bodily functions.

4. Nutrients: These include glucose, amino acids, and lipids, which are used by the body's cells for energy and growth.

5. Waste products: These are substances that the body needs to get rid of, such as urea and carbon dioxide. They are carried in the plasma to the kidneys and lungs, where they can be removed from the body.

6. Hormones, vitamins, and enzymes: These are also carried in the plasma. Hormones are chemical messengers that regulate bodily functions, vitamins are needed for various biochemical reactions, and enzymes speed up these reactions.

7. Gases: Oxygen and carbon dioxide are also carried in the plasma. Oxygen is delivered to cells for respiration, and carbon dioxide, a waste product of respiration, is carried back to the lungs to be exhaled.

8. Antigens and antibodies: These are involved in the body's immune response. Antigens are substances that the body recognizes as foreign, and antibodies are proteins that the immune system produces to fight off these foreign substances.
