Question

Quizplus · Accepted Answer

Aging changes the compliance of the lungs and chest wall. The chest wall progressively stiffens as the thoracic cage joints and attachments calcify and become less mobile. With advancing age, vertebral column deformities produce some degree of kyphoscoliosis. Simultaneously, intercostal and diaphragmatic muscles atrophy, losing strength and endurance. These changes combine to decrease upper and lower rib cage and abdominal expAnswerion.
