The breathing process is primarily controlled by:

  • the diaphragm
  • rib muscles

The diaphragm is a major muscle that separates the thoracic cavity from the abdominal cavity and plays a crucial role in inhalation and exhalation. The rib muscles (intercostal muscles) assist in expanding and contracting the rib cage, facilitating breathing as well.

While the pharynx is involved in the passage of air, it does not control the breathing process. Blood vessels are involved in transporting oxygen and carbon dioxide but do not directly control the mechanics of breathing.

So the correct responses are:

  • the diaphragm
  • rib muscles
