The thoracic wall, also known as the thoracic cage, is a large organ system located in the thoracic cavity, which is the space between the chest and abdomen. This framework supports the lungs and aids in breathing.
The thoracic wall is composed of cartilage, ligaments, and muscles. It consists of two parts: the anterior thoracic wall and the posterior thoracic wall. Together, they provide stability and support to the lungs.
The thoracic wall is responsible for protecting the lungs from external injuries and providing them with the oxygen they need for respiration. It also helps to regulate the volume of the chest cavity, ensuring that the lungs have sufficient space to expand during breathing.
The thoracic wall can be divided into several regions based on its location:
The anterior thoracic wall is the front wall of the chest and is responsible for protecting the heart and other organs.
The posterior thoracic wall is the back wall of the chest and is responsible for supporting the lungs and preventing them from slipping out of place.
The hilum is the opening at the base of the lung where it connects to the bronchi.
The thoracic wall is a vital organ system that plays a crucial role in maintaining respiratory homeostasis. By understanding the structure and function of the thoracic wall, we gain insights into the workings of the human respiratory system
