APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The lungs are a pair of cone-shaped organs made up of spongy, pinkish-gray tissue. They take up most of the space in the chest, or the thorax (the part of the body between the base of the neck and diaphragm). The lungs are covered in a membrane called the pleura.

Detailed explanation-2: -As your diaphragm flattens, it creates more space and reduces pressure in the chest cavity and this pressure change forces air into your lungs. When your diaphragm muscle relaxes, it re-forms the dome shape, which reduces space in the chest cavity and allows air to flow out of the lungs.
