Detailed explanation-1: -Cellular adaptation that occurs due to an increase in workload that results in an increase in the number of cells is: atrophy.
Detailed explanation-2: -In cell biology and pathophysiology, cellular adaptation refers to changes made by a cell in response to adverse or varying environmental changes. The adaptation may be physiologic (normal) or pathologic (abnormal). Four types of morphological adaptations include atrophy, hypertrophy, hyperplasia, and metaplasia.
Detailed explanation-3: -These adaptations include. hypertrophy. (enlargement of individual cells), hyperplasia.
Detailed explanation-4: -Regeneration. Regeneration is the replacement of cell losses by identical cells to maintain tissue or organ size. Hyperplasia. Hyperplasia is an increase in the tissue or organ size due to increased cell number, without an increase in cell size. Hypertrophy. Atrophy. Metaplasia.
