Study Notes
Cancer
- Definition: A mutation in a gene controlling cell division, causing abnormal cell growth
- Benign tumors: Stay in one place
- Malignant tumors: Can spread
- Treatments: Chemotherapy, radiation therapy
Aerobic and Anaerobic Respiration
- Aerobic: Requires oxygen
- Anaerobic: Does not require oxygen
- Path: Air inhaled through nose/mouth, travels down trachea and bronchi, into alveoli, diffuses into blood, carried to heart via vein, oxygenated then sent to muscles via arteries
Diet and Disease
- Poor diet/malnutrition can lead to deficiency diseases
- Diseases and their symptoms:
- Kwashiorkor: Protein deficiency, enlarged belly, swelling gums, tiredness
- Scurvy: Vitamin C deficiency, swelling gums, tiredness
- Sources of nutrients: Fish, red meat, broccoli, oranges
- Non-communicable Diseases: cannot be spread from one person to another:
- Diabetes
- Cancer
- Stroke
- AIDS
