With aging,what changes can be expected in the costal cartilages and thoracic compliance?
A) costal cartilages calcify causing a downward slant of the ribs making the thorax less compliant
B) costal cartilages become more compliant causing the thorax to become more compliant
C) the costal cartilages remain unchanged but the thoracic compliance increases
D) the costal cartilages remain unchanged but the thoracic compliance will decrease

Question

Costal cartilages calcify with aging, which causes a downward slant of the ribs. This calcification makes the thorax less compliant, affecting respiratory mechanics by reducing the chest wall's ability to expand and contract.
