amount of oxygen reaching the tissues.
What are the main types of cellular adaptations?
The main types of cellular adaptations include hypertrophy, hyperplasia, atrophy, and

Aging leads to immunosenescence, characterized by a decline in immune function, increased
susceptibility to infections, and reduced vaccine efficacy.
