Question

Which is the last destination vein for venous blood?

• A. Renal Vein
• B. Cortical Radiate Vein
• C. Arcuate Vein
• D. Interlobar Vein

Hint:

Remember the order: Cortical Radiate → Arcuate → Interlobar → Renal Vein. The renal vein finally drains into the inferior vena cava.

Answer 1

The Correct Option is A

Step 1: Understanding venous drainage of kidney.
Venous blood from the kidney is collected first by the smallest veins known as cortical radiate veins. These veins then converge and drain into arcuate veins.
Step 2: Sequence of venous drainage.
The correct sequence of renal venous drainage is:
Cortical Radiate Veins $\rightarrow$ Arcuate Veins $\rightarrow$ Interlobar Veins $\rightarrow$ Renal Vein.
Step 3: Identifying the final vein.
All the interlobar veins ultimately unite and drain into the renal vein, which is the last destination vein before entering the inferior vena cava.
Final Answer:
\[ \boxed{\text{Renal Vein}} \]
