In response to an increased workload, cardiac myocardial cells will:
A) increase in size.
B) decrease in length.
C) increase in excitability.
D) increase in number.

Question

Quizplus · Accepted Answer

When there is an increased workload, cardiac myocardial cells will increase in size. This is known as hypertrophy. It allows the cells to generate more force and maintain proper contraction during periods of increased demand. The other options, decreasing in length or increasing in excitability, do not make sense in the context of responding to an increased workload. Increasing in number is also unlikely as cardiac cells do not divide and replicate like other types of cells.
