The correct Answer is:
To determine how many statements are correct, let's analyze each statement one by one: 1. **Statement (i)**: "Liver is the site of urine formation." - This statement is **incorrect**. The kidneys are the organs responsible for urine formation, while the liver is involved in the formation of urea, which is a component of urine. 2. **Statement (ii)**: "Urethra is not the part of kidney." - This statement is **correct**. The urethra is a separate structure that connects the bladder to the outside of the body and is not part of the kidney. 3. **Statement (iii)**: "Vasa recta is well developed in cortical nephrons." - This statement is **incorrect**. Vasa recta are well developed in juxtamedullary nephrons, not in cortical nephrons. Cortical nephrons have peritubular capillaries instead. 4. **Statement (iv)**: "The highest concentration of urea is found in the hepatic vein." - This statement is **correct**. The hepatic vein carries blood from the liver, where urea is produced, hence it has a high concentration of urea. 5. **Statement (v)**: "Least concentration of urea is present in renal vein." - This statement is **correct**. The renal vein carries blood away from the kidneys after filtration, resulting in a lower concentration of urea compared to the hepatic vein. Now, let's summarize the correctness of each statement: - Statement (i): Incorrect - Statement (ii): Correct - Statement (iii): Incorrect - Statement (iv): Correct - Statement (v): Correct **Total Correct Statements**: 3 Thus, the answer to the question is **(c) 3**.
