Organ location and awareness

 The liver is located mostly on the right side of your upper abdomen, just beneath the diaphragm and above the stomach.

More precisely:

It sits under the right rib cage.

The right lobe is the largest and takes up much of the right upper quadrant.

The left lobe stretches across the midline toward the left upper quadrant, overlapping slightly with the stomach.

Quick comparison:

Liver → Mostly right side, upper abdomen.

Pancreas → Mostly center-left, behind the stomach.

The pancreas is located in the upper middle to upper left side of your abdomen, behind the stomach.

Specifically:

It spans horizontally across the abdomen.

The head of the pancreas is on the right side, nestled in the curve of the duodenum (the first part of the small intestine).

The body and tail extend to the left side, ending near the spleen.

So, while it's mostly center-left, parts of it extend toward both sides, with the tail more on the left and the head more on the right.
