Answer:
1. The immune system defends against foreign particles.
2. Lymph nodes filter lymph and house immune cells.
3. White blood cells, including lymphocytes, are produced in the bone marrow.
4. Cells include lymphocytes (T cells, B cells, NK cells), lymph nodes, spleen, thymus, and lymphatic vessels. They function in immune response and filtering.
Explanation:
1. The immune system protects the body from harmful invaders like bacteria and viruses.
2. Lymph nodes act as filters, removing impurities from lymph fluid, and house immune cells for defense.
3. White blood cells, including lymphocytes, are produced in the bone marrow to fight infections.
4. Lymphatic system cells, such as T cells and B cells, along with organs like the spleen and thymus, work together to detect and combat pathogens, ensuring a robust immune response.
