Answer 1

The breathing process is controlled by:

• the diaphragm.
• rib muscles.

While the pharynx is involved in the passage of air, and blood vessels influence breathing through the regulation of carbon dioxide and oxygen levels, the primary muscles responsible for the mechanical process of breathing are the diaphragm and rib muscles (intercostal muscles).
