how many sets of ribs in the human body are true
Although fixed into place, these ribs do allow for some outward movement, and this helps stabilize the chest during inhalation and exhalation. The human rib cage is made up of 12 paired rib bones; each are symmetrically paired on a right and left side. Of all 24 ribs, the first seven pairs are often labeled as true. These bones are connected to the costal cartilage, while the five other false sets are not. Three of those connect to non-costal cartilage, and two are deemed to be floating, which means they only connect to the spine.
