Question

In Frog anterior abdominal vein is formed by union of

• A. Sciatic veins
• B. Pelvic veins
• C. Femoral veins
• D. Renal veins

Answer 1

The correct option is B Pelvic veins

In the frog, an abdomen vein is formed by the union of two pelvic vein and vesicular vein.

Pelvic veins are the lateral branches of femoral veins from hind limbs which collect blood from the outer parts of the hind limbs. Vesicular vein collects blood from the urinary bladder.

The anterior abdominal vein runs forward along the mid-ventral line of the body wall, towards the liver. At the anteriormost end, it divides into two branches entering the right and left lobes of the liver where it breaks up into capillaries inside it.

So the correct answer is 'Pelvic veins'.
