Health and Disease: Key Concepts and Prevention Strategies

Life Expectancy

Average period a person is expected to live.

Diabetes Mellitus

Chronic condition affecting blood sugar regulation.

Heart Attack

Blockage of blood flow to the heart muscle.

Bacterial Disease

Infections caused by harmful bacteria.

Immunizations

Vaccines to prevent infectious diseases.

Immunity

Body's ability to resist infections.

Insulin

Hormone regulating blood glucose levels.

Lymphatic System

Network aiding immune response and fluid balance.

Inflammation

Body's response to injury or infection.

Pus

Thick fluid from dead cells and bacteria.

Culture

Growth of microorganisms in controlled conditions.

Cilia

Hair-like structures aiding in movement and filtration.

Cancer Cells

Abnormal cells that invade and destroy healthy tissue.

Mammograms

X-ray screening for breast cancer detection.

Tumor

Abnormal mass of tissue, can be benign or malignant.

Surgical procedure to restore blood flow to the heart.

Red Blood Cells

Cells that transport oxygen throughout the body.

Mucous Membranes

Protective linings that trap pathogens and debris.

Angina Pectoris

Chest pain due to reduced blood flow to the heart.

Echocardiogram

Ultrasound test to visualize heart structure and function.

Health Literacy

Ability to understand health information and make decisions.

Pathogens

Microorganisms that cause disease.

Phagocytes

Cells that engulf and digest pathogens.

Lymphocytes

White blood cells crucial for immune response.

Antibodies

Proteins produced by B-cells to neutralize pathogens.

Health Continuum

Spectrum of health from wellness to illness.

Social Health

Quality of relationships and social networks.

Prevention

Actions taken to reduce disease risk.

Safe Food Handling

Practices to prevent foodborne illnesses.
