In emphysema, the lungs become overdistended with trapped air, which increases the effort required for breathing. Describe the muscles involved when breathing becomes a forced process, such as a patient who has emphysema
What will be an ideal response
During forced inspiration, the scalenes and sternocleidomastoid muscles help lift the ribs. Forced expiration is aided by internal intercostal muscles that pull the ribs inferiorly and by abdominal wall muscles that push the diaphragm superiorly by compressing the abdominal contents.
