Answer:

1)BREATHING: The bodily process of inhalation and exhalation; the process of taking in oxygen from inhaled air and releasing carbon dioxide by exhalation. Inspiration and expiration of air (for oxygen) in the lungs which allows gaseous exchange between the lungs and blood stream.

2)RIBCAGE: The rib cage is the arrangement of ribs attached to the vertebral column and sternum in the thorax of most vertebrates that encloses and protects the vital organs such as the heart, lungs and great vessels.

3)LUNGS: The lungs are a pair of breathing organs located with the chest which remove carbon dioxide from and bring oxygen to the blood.

4)HEART: The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs.
