The correct answer is: C. It is the same as serum but without the clotting proteins.
Blood plasma is the liquid portion of blood that remains after blood cells and clotting factors have been removed. It is a pale yellow, slightly viscous fluid that contains dissolved proteins, electrolytes, glucose, hormones, and other substances. Plasma is responsible for transporting nutrients and oxygen to the cells and removing waste products from the cells. It also helps to regulate blood pressure and body temperature.
Serum is the liquid portion of blood that remains after blood cells have been removed. It is similar to plasma, but it does not contain clotting factors. Serum is used in a variety of medical tests, including blood typing and tests for diseases such as hepatitis and HIV.
Here is a brief explanation of each option:
- A. The main protein component is hemoglobin. Hemoglobin is a protein found in red blood cells that carries oxygen. It is not found in plasma.
- B. It is a faint yellow fluid. This is true. Plasma is a pale yellow, slightly viscous fluid.
- D. It is about 90% water. This is also true. Plasma is about 90% water, with the remaining 10% made up of proteins, electrolytes, glucose, hormones, and other substances.
