B5 Flashcards
What is health defined as?

Influenced by factors like a balanced diet, regular exercise, limited stress, and access to healthcare.
What are the two classifications of diseases?
Communicable and non-communicable diseases
Communicable diseases are infectious, while non-communicable diseases are not.
What causes communicable diseases?
Pathogens like bacteria, viruses, fungi, and protists
Examples include tuberculosis, flu, and malaria.

cancer, diabetes
What factors often lead to non-communicable diseases?
Genetic, lifestyle, or environmental factors
These factors contribute to diseases like cancer and diabetes.
What components make up the immune system?
Physical barriers, white blood cells, and antibodies
Physical barriers include skin.
How can diseases be prevented?
Vaccination, hygiene practices, and controlling risk factors
Risk factors include smoking or poor diet.
True or False: Non-communicable diseases can be transmitted from one individual to another.

How do communicable diseases spread?
They spread through air, water, direct contact, or vectors.
What are non-communicable diseases?
Non-communicable diseases result from genetic, lifestyle, or environmental factors.

Examples include cancer, diabetes, and heart disease.
What is the role of the immune system?
The immune system defends the body through barriers and white blood cells.
What are the types of white blood cells?
Types include phagocytes (engulf pathogens) and lymphocytes (produce antibodies).
How does vaccination work?
Vaccination protects by introducing weakened pathogens, creating memory cells for long-term immunity.
What lifestyle choices can reduce disease risk?
A balanced diet, regular exercise, avoiding smoking, and limiting alcohol intake can reduce disease risk.
