Definition
Apoptosis is a form of programmed cell death that occurs in multicellular organisms. It plays a crucial role in maintaining tissue homeostasis and eliminating damaged or harmful cells.
5 Must Know Facts For Your Next Test
- Apoptosis helps remove damaged lung cells, preventing inflammation and further tissue damage.
- Nutritional deficiencies can impair the apoptotic process, leading to respiratory diseases.
- Antioxidants like vitamins C and E can modulate apoptosis in lung cells, offering protective effects.
- Certain nutrients, such as omega-3 fatty acids, can influence the balance between apoptosis and cell survival in pulmonary tissues.
- Excessive apoptosis in lung tissues can contribute to chronic obstructive pulmonary disease (COPD) progression.
