The Role of the Diaphragm in Breathing
While the lungs play a vital role in the respiratory system, they cannot function alone. The process of breathing relies on the collaboration of various body parts, including muscles. One such muscle, known as the diaphragm, actively assists in the inhalation and exhalation of air.
The Changes in the Respiratory System with Aging
As individuals grow older, their respiratory system undergoes certain alterations. The lungs’ structure, specifically the alveoli, tends to enlarge and lose a portion of their elasticity. Simultaneously, the chest wall gradually decreases in size, resulting in potential difficulties in breathing. Additionally, the strength of the diaphragm muscles tends to diminish over time. Collectively, these changes pose challenges to older adults in terms of respiration, rendering them more susceptible to respiratory conditions like pneumonia.
