What surrounds and protects the lungs?

The ribcage plays a crucial role in surrounding and protecting the lungs. It is composed of ribs that form a bony cage, which not only safeguards the lungs from physical damage but also assists in the mechanics of breathing. When we inhale, the ribcage expands, allowing the lungs to inflate, and during exhalation, it contracts, helping to push air out. This protective structure also provides a barrier against external forces, ensuring the lungs remain safe from injury. The abdominal muscles, spinal column, and pelvic girdle serve various functions in the body but do not specifically encase or protect the lungs in the way that the ribcage does.
