Study Notes
Defining Health
- Health is more than just the absence of illness; it encompasses physical, mental, and social well-being.
- Factors beyond physical health, such as mental well-being and social support, are vital in assessing overall health.
Types of Diseases
- Diseases are conditions where a part of the organism doesn't function correctly.
- Diseases are categorized into communicable and non-communicable.
- Communicable diseases can spread between individuals due to pathogens.
- Non-communicable diseases are not spread between people and arise from issues like genetic problems or lifestyle choices (e.g., cancer, heart disease).
Disease Susceptibility
- Diseases can be correlated, meaning one disease can increase a person's risk of getting another.
- This correlation can stem from various factors:
- Weakened immune systems due to a pre-existing disease which makes individuals more vulnerable to other pathogens.
- Damage to the body's natural barriers, allowing pathogens easier entry.
- Impaired organ systems, making people more susceptible to other diseases.
Communicable Diseases
- Pathogens are disease-causing organisms (viruses, bacteria, fungi, and protists).
- Communicable diseases are caused by pathogens.
- Specific examples of communicable diseases, relevant for exams, are not listed in the provided text.
