With reference to the work of human kidney, consider the following statements:
1. After the waste is removed in the kidney, the cleaner blood is sent back through renal artery.
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?

{'human kidney': [0, 0, 1, 0], 'renal vein': [3, 0, 1, 1], 'kidney': [2, 0, 0, 0], 'renal artery': [1, 0, 1, 0], 'cleaner blood': [0, 0, 1, 0], 'glucose': [8, 0, 3, 5], 'blood': [5, 0, 0, 1], 'waste': [1, 0, 1, 4], 'tiny tubes': [0, 0, 1, 0], 'capsule': [0, 0, 1, 1]}

The correct statement is:

Only 2

Statement 1 is incorrect. After the waste is removed in the kidney, the cleaner blood is not sent back through the renal artery. The renal artery brings oxygenated blood containing waste products into the kidney, and after the filtration process, the filtered blood exits the kidney through the renal vein, not the renal artery.

Statement 2 is correct. From Bowman`s capsule, the filtered liquid, called the glomerular filtrate, passes through tiny tubules known as renal tubules. In the renal tubules, selective reabsorption occurs, where substances like glucose, water, and ions are reabsorbed back into the bloodstream through the peritubular capillaries surrounding the tubules. This reabsorbed material, including much of the glucose, is indeed sent back to the blood in the renal vein.

Therefore, the correct answer is "Only 2."
