Homeostasis

Health

A state of physical, mental, and social well-being.

Disease

A deviation from the normal state of homeostasis.

Health Indicators

Normal values that occur within a range and can vary based on factors like age, gender, genetics, and environment.

Exacerbation

A worsening of the severity of a disease.

Morbidity

Disease rates within a group.

Mortality

The relative number of deaths resulting from a disease.

Cellular Adaptations

Changes in cell size or number in response to stressors, including atrophy, hypertrophy, and hyperplasia.

Apoptosis
