Immune System Review

Front

What are the three layers of the immune system?

Back

1. Physical barriers (e.g., skin, mucous membranes) 2. Innate immune response (e.g., white blood cells, inflammation) 3. Adaptive immune response (e.g., antibodies, T cells)

Front

What is the primary goal of the immune system?

Back

To eliminate pathogens and maintain homeostasis.

Front

Which type of blood cells are responsible for fighting pathogens?

Back

White blood cells (leukocytes) are responsible for fighting pathogens.

Front

What is a pathogen?

Back

A pathogen is an organism that invades the body and causes disease.

Front

How does the body respond to a cut?

Back

The body protects itself by clotting the blood and forming a scab.

Front

What role do antibodies play in the immune system?

Back

Antibodies are proteins produced by B cells that specifically target and neutralize pathogens.

Front

What is the difference between innate and adaptive immunity?

Back

Innate immunity is the body's first line of defense, providing immediate but non-specific responses, while adaptive immunity develops over time and provides specific responses to particular pathogens.

Front

What are the main types of white blood cells involved in the immune response?

Back

The main types of white blood cells include lymphocytes (B cells and T cells), neutrophils, monocytes, eosinophils, and basophils.

Front

How do vaccines work to protect the immune system?

Back

Vaccines stimulate the immune system to recognize and remember specific pathogens, leading to a stronger and faster response upon future exposure.

Front

What is homeostasis in the context of the immune system?

Back

Homeostasis refers to the body's ability to maintain a stable internal environment, including the balance of immune responses.
