The Thorax

Overview

The thorax houses vital organs responsible for respiration and circulation. This section introduces the skeletal framework, musculature and internal structures of the chest cavity, forming the foundation for understanding cardiopulmonary anatomy and physiology.

Key Structures

Learners can explore the lungs and pleura, the heart and great vessels, and the compartments of the mediastinum. Articles detail the anatomy of the diaphragm, thoracic wall and neurovascular bundles, combining structural detail with clear clinical context.

Clinical Relevance and Learning Focus

Knowledge of thoracic anatomy is essential for interpreting chest imaging, performing cardiovascular and respiratory examination, and guiding invasive procedures. Each topic integrates applied clinical anatomy, reinforcing understanding of the thorax in health and disease.
