Question
Which of the following is true about blood plasma? The main protein component is hemoglobin. It is the same as serum but without the clotting proteins. It is about 90% water. It contains about 20 dissolved components.
Solution
The statement that is true about blood plasma is: "It is about 90% water."
Here's why:
-
Blood plasma is not the same as serum but without the clotting proteins. Serum is actually the part of blood that is similar to plasma but without the clotting factors and cells.
-
The main protein component of blood plasma is not hemoglobin. Hemoglobin is found in red blood cells, not in the plasma. The main protein components of plasma are albumin, globulins, and fibrinogen.
-
While blood plasma does contain many dissolved components, the exact number can vary and is not necessarily around 20.
-
Blood plasma is indeed about 90% water. This high water content helps with the transportation of the other components of the blood.
