Question

When a litre of water is introduced in human blood,

• A. BMR decreases
• B. RBCs collapse and urine production increases
• C. BMR increases
• D. RBCs collapse and urine production decreases

Answer 1

The correct option is B RBCs collapse and urine production increases

B. RBCs collapse and urine production increases

Solution: When a litre of water is introduced in human blood, the concentration of water in human blood increases. As RBCs are anucleated cells, water will enter in RBCs and will cause lysis of the cells by the process known as plasmolysis. The increased quantity of water in blood will also increase urine production.

So the correct answer is "RBCs collapse and urine production increases"
