Thoracic anatomy encompasses the structures within the thoracic cavity, including the heart, lungs, and major blood vessels, which are protected by the rib cage. Understanding this anatomy is crucial for diagnosing and treating conditions affecting the respiratory and cardiovascular systems.

Structures within the thoracic cavity

The heart

The lungs are vital respiratory organs responsible for the exchange of oxygen and carbon dioxide between the bloodstream and the environment, playing a crucial role in maintaining the body's metabolic processes. They consist of a complex system of airways and alveoli, which maximize surface area for efficient gas exchange and are protected by the rib cage and diaphragm for mechanical support and ventilation.

Lungs

Major Blood Vessels

The rib cage is a bony structure that surrounds the thoracic cavity, providing protection for vital organs such as the heart and lungs while also supporting the upper body and aiding in respiration. It consists of 12 pairs of ribs, the sternum, and the thoracic vertebrae, forming a flexible yet sturdy framework essential for breathing and movement.

Diagnosing Conditions

Treating conditions

The respiratory system is responsible for the exchange of gases, primarily oxygen and carbon dioxide, between the body and the environment. It involves a series of organs and structures that facilitate breathing, ensuring that oxygen reaches the bloodstream while expelling carbon dioxide from the body.
