THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The spleen varies in size and shape between people, but it’s commonly fist-shaped, purple, and about 4 inches long. Because the spleen is protected by the rib cage, you can’t easily feel it unless it’s abnormally enlarged. The spleen plays multiple supporting roles in the body.

Detailed explanation-2: -Normally, a developed spleen lies in the upper left quadrant in parallel with the long axis of the 10th rib.

Detailed explanation-3: -The average position is at the level of the lower third of the tenth thoracic vertebra. Piersol places the highest point of the spleen at the level of the ninth thoracic vertebra, whereas Joessel places it at the level of the tenth thoracic vertebra.
