Flashcard: Immune System

Front

What are antibodies?

Back

Proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses.

Front

What triggers the production of antibodies in the body?

Back

The detection of foreign antigens.

Front

What is the role of a fever in the immune response?

Back

A fever is an immune response that helps the body fight off infections by creating an environment less favorable for pathogens.

Front

What are white blood cells?

Back

Cells of the immune system that help the body fight infections and other diseases.

Front

What is a vaccine?

Back

A substance that stimulates the body's immune response against future infections, often containing weakened or inactive pathogens.

Front

What is the difference between antigens and antibodies?

Back

Antigens are substances that trigger an immune response, while antibodies are produced by the immune system to neutralize antigens.

Front

What is the function of T-cells in the immune system?

Back

T-cells are a type of white blood cell that play a central role in cell-mediated immunity, helping to destroy infected or cancerous cells.

Front

What is the significance of the immune response?

Back

The immune response is crucial for protecting the body against infections and diseases by identifying and eliminating pathogens.

Front

What are weakened pathogens in vaccines?

Back

Weakened pathogens are live viruses or bacteria that have been altered to not cause disease but still provoke an immune response.

Front

How do vaccines prepare the immune system?

Back

Vaccines expose the immune system to a harmless form of a pathogen, allowing it to recognize and respond more effectively to future infections.
