🌟 Detailed Explanation

Anatomy of the Thoracic Cavity

The thoracic cavity, also known as the chest cavity, is located between the neck and the diaphragm. It houses crucial organs like the lungs, heart, and major blood vessels 🫁❤️. The cavity is enclosed and protected by the rib cage, which acts as a shield against external damage 🦴.

Lungs and Their Function

The primary function of the lungs is gas exchange. They take in oxygen from the air and expel carbon dioxide, a waste product of metabolism 🌬️. This process occurs in the alveoli, tiny air sacs in the lungs that provide a large surface area for efficient gas exchange.

Protection of the Lungs

The lungs are protected by a layer of pleural fluid that reduces friction and ensures smooth movement during breathing 🫁. The pleura, a double-layered membrane, surrounds each lung, helping it expand and contract while maintaining a barrier against infection.
