Immune System

The immune system is a complex network of structures that includes white blood cells, the thymus, spleen, lymph nodes, and lymph vessels. White blood cells (leukocytes, thrombocytes, granulocytes, and lymphocytes) play a crucial role in defending the body against invaders. The thymus helps mature T-cells, while the spleen contributes to blood filtration and storage. Lymph nodes filter germs, and lymph vessels transport fatty acids and fluids. This system interacts with the circulatory system to protect against infections and may be affected by conditions like allergies, asthma, and cancer.

  4. B. Thymus • 1. The Thymus is a specialized organ of the Immune System.

  5. C. Spleen • 1. The spleen functions as part of the Immune System and contributes to the production and storage of the Circulatory System.

  6. D. Lymph Nodes • 1. Lymph nodes work like filters to remove germs that could get you sick.

  7. E. Lymph Vessels • 1. Lymph vessels transport fatty acids and glycerol as well as excess tissue fluids.

  8. II. • How specifically does the immune system work? 1.The Immune System defends the body from attack by invaders recurring.

  9. III. • What is relationship of the Immune System and other body systems? 1.With circulatory system allows the immune cells to travel throughout the body and survey for infection.
