Lymphatic & Immune System

Front

What is the primary function of macrophages in the immune system?

Back

Macrophages are responsible for engulfing pathogens and presenting their antigens to other immune cells, thus playing a crucial role in initiating the immune response.

Front

Where is the spleen located in the human body?

Back

The spleen is located in the upper left quadrant of the abdomen, next to the stomach.

Front

What is a non-specific immune response?

Back

A non-specific immune response is a general defense mechanism that the body employs against pathogens, such as fever, which helps to create an unfavorable environment for pathogens.

Front

What are lymph nodes?

Back

Lymph nodes are tiny oval-shaped structures located throughout the body that filter lymph fluid and house immune cells.

Front

What is the role of memory B cells in the immune response?

Back

Memory B cells are responsible for providing a faster and more effective secondary immune response upon re-exposure to a previously encountered pathogen.

Front

Define lymphatic system.

Back

The lymphatic system is a network of vessels and organs that helps maintain fluid balance, absorb fats from the digestive system, and plays a key role in the immune response.

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 host cells and regulate the immune response.

Front

What is the difference between specific and non-specific immunity?

Back

Specific immunity targets specific pathogens and involves memory cells, while non-specific immunity provides a general defense against all pathogens.

Front

What is the role of antibodies in the immune system?

Back

Antibodies are proteins produced by B cells that specifically bind to antigens on pathogens, marking them for destruction by other immune cells.

Front

What is the function of the thymus gland?

Back

The thymus gland is responsible for the maturation of T cells, which are essential for the adaptive immune response.
