Spleen, Anterior View

Description

Positioned in the left upper quadrant, the spleen sits deep to ribs 9 to 11 along the midaxillary line, with its long axis paralleling the costal margin in an anterior perspective of a male torso. The convex diaphragmatic surface faces superolaterally toward the left hemidiaphragm, while the visceral surface turns inferomedially toward the stomach and left kidney. Medially, the splenic hilum is visible as the entry and exit point for the splenic artery and splenic vein, with the tail of the pancreas approaching the hilum in close proximity. Translucent ribs and thoracolumbar spine provide bony landmarks for depth and orientation. That spatial relationship matters in practice because most of the spleen is shielded by the lower left ribs, so blunt trauma can produce splenic laceration and hemoperitoneum even when the abdominal wall looks unremarkable. An anterior view that keeps the rib cage readable helps you teach why left lower rib fractures raise suspicion for splenic injury and why an enlarged spleen (hypersplenism in portal hypertension or hematologic malignancy) becomes palpable by expanding anteroinferiorly beyond the costal margin. The hilum is also the operative gateway: vascular control during splenectomy targets the splenic pedicle while avoiding injury to the pancreatic tail. Use this artwork in gross anatomy labs, abdominal surgery teaching files, or emergency medicine lectures that cover left upper quadrant trauma assessment, FAST interpretation, and splenic preservation versus splenectomy. It also fits hematology and immunology content on lymphoid function and extramedullary hematopoiesis, where location and peritoneal relations frame clinical signs and procedural risk.
