Question

Quizplus · Accepted Answer

As the body ages, the tendons and muscles that support and expand the lungs, chest and ribs become less flexible and stiffen which leads to a decrease in the vital capacity of the lungs. Contaminants inhaled during adolescence, weakening of the heart walls, and hormone changes that affect the cardiovascular system may also have negative effects on respiratory function, but they are not direct factors that lead to changes in vital capacity with ageing.
