How does an immune response occur?

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.

Which component is part of the immune system and function in immune response?

The main parts of the immune system are: white blood cells, antibodies, the complement system, the lymphatic system, the spleen, the thymus, and the bone marrow. These are the parts of your immune system that actively fight infection.

What specific part of the pathogen does the immune system actually react to?

Specific immune responses are triggered by antigens. Antigens are usually found on the surface of pathogens and are unique to that particular pathogen. The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies.

Which cell component is part of the immune system?

The cells of the immune system can be categorized as lymphocytes (T-cells, B-cells and NK cells), neutrophils, and monocytes/macrophages. These are all types of white blood cells. The major proteins of the immune system are predominantly signaling proteins (often called cytokines), antibodies, and complement proteins.

Where do immune cells reside?

The cells of the immune system originate in the bone marrow, where many of them also mature. They then migrate to guard the peripheral tissues, circulating in the blood and in a specialized system of vessels called the lymphatic system.

How does your immune system remember a particular pathogen?

To understand the human body’s response to the virus, scientists are looking at antibodies and beyond to other elaborate biological responses, such as T cells and memory cells, that cause a person’s immune system to recognize a virus from a previous infection and eliminate the pathogen before it infiltrates cells.

What body system that interacts with the immune system?

The immune system works closely with other body systems, including the integumentary, circulatory, and lymphatic systems.

How does the immune system interact with the respiratory system?

The removal of this debris is an important part of the immune system protecting the respiratory system from infections. The epithelial linings of the lungs also contain specialised white blood cells called macrophages which are able to engulf and destroy foreign particles in the lungs.
