During the resting heart, that is, the number of times the heart beats per minute while the body is relaxed and at rest does not change significantly with age; But with age, there are changes in the ability of the heart to increase its rate during exercise and other moments of stress. Younger hearts usually usually speed up more faster than older ones when challenged. The maximum heart rate, the highest heart rate one can achieve as measured by a cardiac stress test declines gradually in adults as they age. The cause of this is slowing down of the heart's pacemaker cells.

<em>His decreased residual volume and decreased lung compliance contribute to his altered ventilation.
</em>
Explanation:
Pneumoconioses are distinguished by reduced residual volume and impaired compliance with the lungs.
Pneumoconiosis involves asbestosis, silicosis, and the pneumoconiosis (CWP) of coal workers.
The most prevalent mineral dusts proven to cause pneumoconiosis in the workplace are asbestos, silica (rock and sand dust), and coal dust.
Cough and shortness of breath are by far the most common symptoms of pneumoconiosis. The threat is usually greater when people are exposed to high levels and/or long periods of time from mineral dusts.
One risk factor is the insufficient or inconsistent usage of personal protective equipment (PPE) such as respirators (specially designed breathing masks), as avoiding inhalation of dusts would also avoid pneumoconiosis.
