Matt: 肥大（Hypertrophy）通常是指某物尺寸的增加，而增生（hyperplasia）是指某物数量的增加。这两种情况都是细胞或组织为了适应压力，维持体内平衡而发生的。细胞在受到压力时，会通过增加自身的大小或数量来适应，以克服这些压力。具体选择哪种适应方式，取决于组织类型和细胞的特性。有些组织具有干细胞，可以通过细胞分裂增加细胞数量（增生），而另一些组织则不具备这种能力，只能通过增加单个细胞的大小（肥大）来适应。
Deep Dive
This chapter defines hypertrophy and hyperplasia, differentiating between increase in cell size and increase in cell number. It uses the analogy of lawn mowing to illustrate these concepts and provides examples of tissues where each process occurs.
- Hypertrophy is an increase in the size of a cell or tissue.
- Hyperplasia is an increase in the number of cells.
- Muscle cells can undergo hypertrophy but not hyperplasia.
