Answer 1

Explanation:

The ribs are the bony framework of the thoracic cavity. The ribs form the main structure of the thoracic cage protecting the thoracic organs, however their main function is to aid respiration. There are twelve pairs of ribs. Each rib articulates posteriorly with two thoracic vertebrae by the costovertebral joint.

Entry 1 of 4) 1a : any of the paired curved bony or partly cartilaginous rods that stiffen the walls of the body of most vertebrates and protect the viscera. b(1) : a cut of meat including a rib — see beef illustration. (2) : a boneless cut of meat (such as beef or pork) from a rib section.

Rib cage consists of 12 pairs of ribs, sternum, xiphoid process, costal cartilages and 12 thoracic vertebrae. It protects heart, lungs and diaphragm. It provides a framework on which the muscles of the shoulder girdle, chest, upper abdomen and back can attach. It also plays important role in the respiration.
