THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Some people are born without a spleen or need to have it removed because of disease or injury. The spleen is a fist-sized organ found in the upper left side of your abdomen, next to your stomach and behind your left ribs. It’s an important part of your immune system but you can survive without it.

Detailed explanation-2: -The spleen has an anterior and posterior segment and rests on the upper pole of the left kidney and tail of the pancreas. The spleen has 3 distinct borders: superior, inferior, and intermediate. The superior border of the spleen has a notch on the anterior end. The spleen has 2 surfaces, the visceral and diaphragmatic.

Detailed explanation-3: -This artery supplies the spleen, as well as large portions of the pancreas and stomach. It runs anterior to the left kidney and suprarenal gland, and posterior to the stomach, through the peritoneal splenorenal ligament and along the tail of the pancreas.
