Study Notes
Cancer
- Definition: A mutation in a gene controlling cell division, causing cells to divide abnormally, resulting in a tumor.
- Benign Tumor: Stays in one place, weaker.
- Malignant Tumor: May spread, stronger.
- Treatment: Chemotherapy, radiation therapy.
Aerobic and Anaerobic Respiration
- Aerobic Respiration: Requires oxygen.
- Path: Oxygen inhaled through nose/mouth, down trachea and bronchi, into alveoli. Diffuses into bloodstream, carried to heart, right atrium, then to working muscles via arteries.
- Anaerobic Respiration: Does not require oxygen.
Diet and Health
- Diet impacts health significantly.
- Deficiency diseases: Diseases caused by nutrient deficiencies.
- Examples: Rickets, Anemia.
- Symptoms of deficiency diseases include: Soft bones, tiredness.
- Food sources of nutrients: Fish, red meat, eggs, broccoli, orange.
Non-Communicable Diseases
- Definition: Diseases that cannot be transferred or spread from one person to another.
- Examples: Diabetes, Cancer, Stroke, AIDS.
- Cancer: Can be a result of poor diet or malnutrition, leading to nutrient deficiencies.
