Mellkasfalat

Mellkasfalat is a Hungarian term that translates to "chest wall" in English. It refers to the bony and muscular structure that encloses the thoracic cavity. This vital structure is composed of the ribs, the sternum (breastbone), the thoracic vertebrae, and the intercostal muscles. The primary function of the chest wall is to protect the internal organs of the thorax, including the heart and lungs, from external injury.

The chest wall also plays a crucial role in respiration. During inhalation, the intercostal muscles contract, lifting the ribs and expanding the chest cavity. This expansion creates a lower pressure within the lungs than the surrounding atmosphere, causing air to flow in. During exhalation, these muscles relax, allowing the chest cavity to decrease in size and forcing air out of the lungs.

Injuries to the chest wall can range from simple bruises and rib fractures to more severe conditions like flail chest, where a segment of the chest wall becomes detached due to multiple rib fractures. These injuries can impair breathing and require medical attention. The anatomy and integrity of the chest wall are essential for both protection and the fundamental process of breathing.
