Solution
The correct option is D Lymph
- As the blood passes through the capillaries in tissues, some 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 (RBC, WBC, and platelets) in the blood vessels.
- This fluid released out is called the interstitial fluid or tissue fluid. It has the same mineral distribution as that in plasma. The exchange of nutrients, gases, etc., between the blood and the cells, always occurs through this fluid.
- An elaborate network of vessels called the lymphatic system collects this fluid and drains it back to the major veins. The fluid present in the lymphatic system is called lymph. Hence, lymph acts as the middleman.
So, the correct answer is 'Lymph'.
