Final answer:
Atherosclerosis could have potentially led to Mr. Getz's collapse, since it narrows and hardens the arteries, which could cause a heart attack or stroke during physically demanding activities under heat stress.
Step-by-step explanation:
Yes, atherosclerosis could have potentially led to Mr. Getz's collapse. Atherosclerosis is a condition where arteries become narrowed and hardened due to a buildup of plaque, which can lead to various cardiovascular diseases. When individuals have significant atherosclerosis, especially in arteries supplying the heart or brain, they are at an increased risk of heart attacks and strokes.
During a hot summer afternoon, the body's demands for oxygen and nutrients increase, especially in someone doing physical work like mowing the lawn. If Mr. Getz's arteries were unable to supply adequate blood due to the plaque buildup, it could have led to insufficient blood flow and oxygen to vital organs, causing him to collapse. The heat could also contribute to the strain on Mr. Getz's cardiovascular system, increasing the likelihood of such an event. It is equally important to consider that direct medical attention is needed to assess the situation properly and provide the necessary care.
