Final answer:
The false statement about plasma is that its concentration of protein is less than that of interstitial fluid. Contrarily, plasma's higher protein concentration helps maintain blood volume and pressure through osmotic pressure gradient.
Step-by-step explanation:
Among the statements provided about plasma , the false one is: b. Its concentration of protein is less than that of interstitial fluid creating a blood colloid osmotic pressure gradient. This statement is incorrect because the concentration of protein in the plasma is higher than in the interstitial fluid, which indeed creates an osmotic pressure gradient that helps to draw water into the circulatory system and maintain blood volume and pressure.
Plasma, the liquid portion of blood, is composed mainly of water, about 92% water to be more precise. It is a straw-colored fluid that contains vital components such as plasma protien (like albumins, globulins including immunoglobulins, and fibrinogen), organic nutrients (like glucose and amino acids), electrolytes, and respiratory gases.
Albumin, which is the most abundant plasma protein and produced by the liver, crucially contributes to the osmotic pressure of blood. In contrast, globulins play significant roles in transport and immunity. These attributes highlight the complex and essential nature of plasma in maintaining overall bodily function.
