Question

• B. Absence of WBC
• C. Number of WBC is less in blood
• D. None of the above

Answer 1

The correct option is A Absence of RBC

Blood is a special connective tissue consisting of a fluid matrix, plasma, and formed elements. 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. 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 the lymph. WBC are present in lymph. Hence the main difference in blood and lymph is the absence of RBC.

So, the correct answer is 'Absence of RBC'.
