Urine flows into ureters from

Options

A. Kidney pelvis
B. Urinary bladder
C. Urethra
D. Collecting ducts

Answer

**Step-by-Step Solution:**

1. **Understanding Urine Formation**: Urine is formed in the kidneys, specifically in the nephrons, which are the functional units of the kidney.

2. **Collection of Urine**: After urine is filtered in the nephron, it is collected by the collecting ducts.

3. **Minor Calyx Formation**: The collecting ducts converge to form the minor calyx, which is a funnel-shaped structure.

4. **Major Calyx Formation**: Several minor calyces join together to form the major calyx.

5. **Renal Pelvis**: The major calyces then converge to form the renal pelvis, which acts as a funnel for urine.

6. **Flow into Ureters**: From the renal pelvis, urine flows into the ureters. The ureters are tubes that transport urine from the kidneys to the urinary bladder.

7. **Storage and Excretion**: The urinary bladder stores urine until it is excreted from the body through the urethra.

8. **Conclusion**: Therefore, the urine flows into the ureters from the renal pelvis.

**Final Answer**: Urine flows into the ureters from the renal pelvis.
