@nursewellversed: The immune system is made up of organs, glands, blood cells, and antibodies that defend the body against foreign invaders (antigens) like bacteria, viruses, and toxins. When it detects an antigen, it produces antibodies—proteins that recognize and help destroy the invader. 🛡️ Key Players in the Immune System: 🔹 Thymus – Helps T-cells develop to attack infected cells and regulate immune responses
🔹 Spleen – Filters blood, removes damaged cells, helps detect infection
🔹 Appendix – Stores “good” gut bacteria and immune cells
🔹 Bone Marrow – Produces RBCs (oxygen), WBCs (fight infection), PLTs (clotting)
🔹 Tonsils – First line of defense, trap germs before they enter the body
🔹 Lymphatic System – Produces lymphocytes, filters harmful substances, and maintains fluid balance 💬 Comment below if you want to learn more about the immune system! #nursingschool #nursingeducation #nursingstudent #nclexreview #futurenurse
