The Abdomen

Overview

The abdomen contains many of the body’s vital organs and plays a central role in digestion, circulation and immunity. This section examines the layered anatomy of the abdominal wall and the organisation of the internal viscera. It offers a structured approach to understanding spatial relationships within the peritoneal cavity and their clinical significance.

Key Structures

Learners can explore the boundaries of the abdominal wall, the arrangement of muscles and fascia, and the contents of the peritoneal cavity. Articles detail the anatomy of the gastrointestinal tract, hepatobiliary system, pancreas, spleen and major vessels. Each topic is illustrated with labelled diagrams and linked to clinical imaging for integrated understanding.

Clinical Relevance and Learning Focus

A thorough grasp of abdominal anatomy supports clinical examination, surgical procedures and interpretation of radiological findings. This section connects anatomical detail with common presentations such as hernias, organ enlargement and referred pain, helping learners translate structural knowledge into clinical reasoning.
