Question

Parts of body that helps in proper functioning of lungs-
Chest cavity and Ribs
Rib cage and Diaphragm
Vertebral column and Diaphragm
Windpipe and Lungs​

Answer 1

Answer:

The heart and the lungs reside in the thoracic cavity, as well as many blood vessels.

Explanation:

When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
