Breathing depends on pressure changes produced by respiratory muscles, principally the diaphragm and intercostal muscles.
The right ventricle pumps blood to the lungs for oxygenation, and pulmonary veins return oxygenated blood to the left atrium.
Cartilage rings and elastic ligaments keep the trachea and laryngeal airways open during pressure changes.
