Question

lo 3.5. what is the function of the thoracic cage? facilitate the movement of the limbs. store and produce red blood cells. protect the organs within the chest. regulate the oxygen levels in the blood. maintain balance and posture of the body.

Explanation:

The thoracic cage, composed of ribs, sternum and thoracic vertebrae, forms a protective bony - cartilaginous enclosure around the chest organs like the heart and lungs. It does not primarily facilitate limb movement, store/produce red blood cells (bone marrow does that), regulate blood oxygen levels (lungs do that mainly), or maintain body balance and posture (muscles and other skeletal - muscular structures do that). Its main function is protection.

Answer:

Protect the organs within the chest.
