What are the eight organs of the immune system?

The eight organs of the immune system are the tonsils, thymus, bone marrow, spleen, lymph nodes, adenoids, appendix, and Peyer's patches in the small intestine. These organs play crucial roles in the immune response, such as producing and storing immune cells, filtering pathogens from the bloodstream, and coordinating immune responses.

Does the thymus has roles in the digestive and lymphatic systems?

AIDS cripples the immune system by interfering with activity of cells called?

HIV cripples the immune system by infecting and killing helper T cells (specifically CD4+ T cells), macrophages, and dendritic cells. These cells hold crucial roles in the immune system in identifying and destroying antigens (foreign invaders). Over time, this destruction of the immune system causes the Acquired Immunodeficiency Syndrome (AIDS).


What are the key differences in the functions and roles of macrophages versus dendritic cells in the immune system?

Macrophages are large immune cells that engulf and digest pathogens, dead cells, and debris. They also help regulate inflammation and tissue repair. Dendritic cells are specialized in capturing and presenting antigens to activate T cells, initiating immune responses. Both play crucial roles in the immune system, but macrophages focus on clearing debris and maintaining tissue homeostasis, while dendritic cells are key in initiating adaptive immune responses.


Immune system facts?

The immune system is a complex network of cells, tissues, and organs that work together to protect the body from viruses, bacteria, and other harmful substances. It has two main components: the innate immune system, which provides immediate, general protection against pathogens, and the adaptive immune system, which develops a specific response to each pathogen. Immune cells like white blood cells, antibodies, and cytokines play crucial roles in identifying and destroying harmful invaders while also maintaining tolerance to the body's own cells. A healthy immune system is essential for overall well-being, and lifestyle factors like diet, exercise, sleep, and stress management can all influence its function.
