Increase in the size of an organ caused by an increase in the size of?

Increase in the size of an organ caused by an increase in the size of its cells is referred to as hypertrophy. This process can occur in response to increased workload or hormonal stimulation, leading to enhanced function of the organ. Unlike hyperplasia, which involves an increase in the number of cells, hypertrophy focuses on the enlargement of existing cells. Common examples include muscle hypertrophy from strength training and cardiac hypertrophy from increased blood pressure.
