The chest cavity is where your heart, lungs, and esophagus reside. It's essentially everything located behind the chest wall, but in front of the spine, above the diaphragm and below the throat.
The heart is within the chest cavity. It is located medially in the chest cavity.
The diaphragm is normally dome-shaped & arches up into the chest cavity, but during inhalation it contracts & flattens down, and at the same time, the intercostal muscles expand the ribcage; these two actions increase the chest capacity by up to 75%.
The function of the chest cavity is to support some internal organs. The lungs and the heart are located in the chest cavity which protects and supports them.
