The liver consists of 4 distinct lobes – the left, right, caudate, and quadrate lobes.
The left and right lobes are the largest lobes and are separated by the falciform ligament. The right lobe is about 5 to 6 times larger than the tapered left lobe.
The small caudate lobe extends from the posterior side of the right lobe and wraps around the inferior vena cava.
The small quadrate lobe is inferior to the caudate lobe and extends from the posterior side of the right lobe and wraps around the gallbladder.
