Given below are two statements: Statement I: Exchange of nutrients and gases between the blood and the cells always occurs through the interstitial fluid. Statement II: As blood passes through tissue capillaries, larger proteins and most of the formed elements move out into the intercellular spaces to form tissue fluid. In the light of the above statements, choose the most appropriate answer from the options given be

Step-by-step solution

As blood passes through the capillaries in tissues, water along with many small water-soluble substances move out into the spaces between the cells of tissues, leaving the larger proteins and most of the formed elements in the blood vessels. This fluid released out is called the interstitial fluid or tissue fluid. Therefore, Statement II is incorrect because larger proteins and formed elements do not move out into the intercellular spaces. The interstitial fluid has the same mineral distribution as that in plasma.
