Immune System Flashcard

Front

What are Phagocytes?

Back

Phagocytes are a type of immune cell that engulf and digest pathogens and debris. They play a crucial role in the innate immune response.

Front

What is the adaptive immune response?

Back

The adaptive immune response is a specific immune response that involves T and B cells, which can recognize and remember specific pathogens.

Front

What is the difference between innate and adaptive immunity?

Back

Innate immunity is the first line of defense and is non-specific, while adaptive immunity is specific and involves memory cells for long-term protection.

Front

What role do B-Cells play in the immune system?

Back

B-Cells are responsible for producing antibodies that target specific antigens on pathogens.

Front

Where do T-lymphocytes mature?

Back

T-lymphocytes mature in the thymus gland.

Front

What is the function of Helper T-Cells?

Back

Helper T-Cells assist other immune cells by releasing cytokines and enhancing the immune response.

Front

What are antibodies?

Back

Antibodies are proteins produced by B-Cells that specifically bind to antigens to neutralize or mark them for destruction.

Front

What is the role of macrophages in the immune system?

Back

Macrophages are large phagocytic cells that engulf and digest pathogens and also present antigens to T-Cells.

Front

What is the significance of memory cells in the adaptive immune response?

Back

Memory cells provide long-term immunity by remembering past infections and responding more rapidly upon re-exposure to the same pathogen.

Front

What is the function of Cytotoxic T-Cells?

Back

Cytotoxic T-Cells directly kill infected body cells and cancer cells.
