What are the four characteristics of the immune system?
There are four characteristics of adaptive immunity: antigenic specificity, diversity, immunologic memory and ability to distinguish between self and non-self.
An immune response involves Lymphocytes (B-cells and T-cells) and antigen presenting cells (macrophages, B-cells, and dendritic cells)..
Which are the most important characteristics of the immune response?
Because immune responses exhibit the characteristics of self-tolerance, specificity, and memory, a healthy body is well equipped to remove foreign invaders and prevent recurrent infections. Age, nutrition, exercise, and stress all affect the ability of the body to fight disease.

Which is characteristic of natural immunity?
Innate immune response is characterized by its ability to distinguish structural components from microbial pathogens, which are present only in these microorganisms and are absent in the normal host cells.
What are the two types of immune system?
The immune system is made up of two parts: the innate, (general) immune system and the adaptive (specialized) immune system. These two systems work closely together and take on different tasks.
What are the three major functions of the immune system?
Describe the three major functions of the immune system. Battle infection. Maintains homeostasis by eliminating damaged cells. Protects the body against foreign organisms.
What happens during immune response?
The immune system recognizes and destroys, or tries to destroy, substances that contain antigens. Your body’s cells have proteins that are antigens. These include a group of antigens called HLA antigens. Your immune system learns to see these antigens as normal and usually does not react against them.
What is primary immune response?
Definition. Primary Immune Response is the reaction of the immune system when it contacts an antigen for the first time. Secondary Immune Response is the reaction of the immune system when it contacts an antigen for the second and subsequent times.
What is the main organ of the immune system?
The key primary lymphoid organs of the immune system are the thymus and bone marrow, and secondary lymphatic tissues such as spleen, tonsils, lymph vessels, lymph nodes, adenoids, and skin and liver.
