With reference to the work of human kidney, consider the following statements: 1. 1. After the waste is removed in the kidney, the cleaner blood is sent back through renal artery. 2. 2. From Bowman's capsule, the filtered liquid passes through tiny tubes where much of the glucose is reabsorbed and sent back to the blood in the renal vein. Which of these statements is/the correct?

1 Statement 1 is incorrect. Blood enters the kidney via the renal artery and waste is removed through filtration and secretion. The cleaner blood leaves the kidney via the renal vein, not the renal artery. The renal artery brings unfiltered blood to the kidney. 2 Statement 2 is incorrect. While filtered liquid passes from Bowman's capsule into tiny tubes (renal tubules) where glucose is reabsorbed, this reabsorbed glucose returns to the blood circulating in the peritubular capillaries, which eventually drain into the renal vein. The statement is somewhat imprecise but fundamentally points to reabsorption back into the blood via the renal vein system, but the initial statement (1) about blood flow direction is definitively wrong.
