Lymphatic and immune system
| Question | Answer |
|---|---|
| What is the primary function of the lymphatic system? | To transport lymph, a fluid containing infection-fighting white blood cells, throughout the body. |
| What are lymph nodes? | Small, bean-shaped structures that filter lymph and store white blood cells to help fight infection. |
| Name two primary lymphoid organs: | The thymus and bone marrow. |
| What is the role of the spleen in the lymphatic system? | It filters blood, removes old or damaged red blood cells, and helps fight infection. |
| What is lymph? | A clear fluid that travels through the lymphatic system, carrying cells that help fight infections and other diseases. |
| What are the two main types of immunity in the immune system? | Innate immunity and adaptive immunity. |
| What is the function of T cells in the immune system? | T cells help protect the body from infection by attacking infected cells and activating other immune cells. |
| What is the role of B cells in the immune system? | B cells produce antibodies that bind to specific antigens to neutralize or destroy pathogens. |
| What is an antigen? | A substance that the immune system recognizes as foreign and that can provoke an immune response. |
| What is the function of the thymus? | The thymus is where T cells mature and become capable of responding to pathogens. |
| How does the lymphatic system contribute to fat absorption? | It absorbs fats and fat-soluble vitamins from the digestive system and transports them to the bloodstream. |
| What is the difference between innate and adaptive immunity? | Innate immunity provides immediate, non-specific defense against pathogens, while adaptive immunity provides a specific response to pathogens and has memory. |
| What are macrophages? | Large white blood cells that engulf and digest pathogens and cellular debris. |
| What is the role of the tonsils in the lymphatic system? | The tonsils trap pathogens from the food and air we ingest and help activate the immune response. |
| What is the function of lymphatic vessels? | They transport lymph throughout the body, returning it to the bloodstream and helping to maintain fluid balance. |
