The respiratory system consists of many organs and tissues. It includes the nasal chamber, pharynx, larynx, trachea, primary, secondary and tertiary bronchi, alveolar duct, alveolar sac, and alveoli. All of these parts work together in the process of breathing. The oxygen moves throughout the body and the waste gases like carbon dioxide are removed.
Transversus thoracis are the accessory respiratory muscles. These muscles remain active during the process of forceful expiration. The muscles pull the ribs towards the sternum that results in a decreased anteroposterior diameter of the thoracic cavity.
Hence, option d is correct.
