Osmosis video - Hyperplasia and hypertrophy

Hyperplasia and hypertrophy are two ways that the size of cells can increase. Hyperplasia is an increase in the number of cells, while hypertrophy is an increase in the size of cells. During hypertrophy, the cells enlarge as they fill with more cytoplasm. This can lead to an increase in the strength or function of the tissue. During hyperplasia, new cells are formed as existing cells divide. This can lead to an increase in the number of cells and the overall size of the tissue.
