How the Immune System Fights Disease The immune system can mount a variety of responses to attack specific invader organisms. One of these responses is coordinated by T-helper cells (also known as T cells, T4 cells, or CD4 cells), which act as a kind of orchestra conductor. The T-helper cells tell other cells what to do when this response is triggered.

How the Immune System Fights Disease How the Immune System Fights Disease. Introduction. The immune system is a complex network of cells and chemicals. Its mission is to protect us against foreign organisms and substances. The cells in the immune system have the ability to recognize something as either self or invader, and they try to get rid of anything that is an invader.

- Your white blood cells are the blood cells that fight infections and disease. Infections are caused by fungi, viruses and bacteria. You white blood cells produce these things …called antibodies which sort of eat up the microbes inside of your body. Microbes cause disease when they are able to reproduce in the body. They produce harmful substances called toxins, and damage tissues and organs.

The immune system and cancer The immune system protects the body against illness and infection caused by bacteria, viruses, fungi or parasites. It is really a collection of reactions and responses that the body makes to damaged cells or infection.ancer can weaken the immune system by spreading into the bone marrow. The bone marrow makes blood cells that help to fight infection. Weakening of the immune system happens most often in leukaemia or lymphoma. But it can happen with other cancers too.

How Does The Immune System Protect Us From Disease The immune system protects against disease through a series of steps called the immune response. The cells that are responsible for the body’s reaction to a disease are the white blood cells or leukocytes. There are two main types of these cells which play an important part in the protection of the body against disease.5 Jun, 2011 Health 0. The immune system is a collection of different body systems and cells that protect our body from bacterial and viral infection. This biological system identifies and attacks foreign cells and materials through specialized cells called B-cells.

Unsolved Mysteries of Human Health Your body has an amazing internal defense mechanism called the immune system which protects you from bacteria and viruses that can lead to illness. A healthy immune system produces a variety of different cells to attack the invading bacteria and viruses. Your blood contains many different types of cells. Red blood cells carry oxygen to all the parts of your body. Platelets stop bleeding by helping with blood clotting.

How do white blood cells fight infection? 1 Answer. There are three ways in which white blood cells (WBCs) fight infection. 1. through a process called phagocytosis, the WBC engulf the pathogens in the body, and in layman terms swallow them sort of. This is done by the category of WBCs called T cells 2.

The immune system is the body's protection against invasion of antigens such as bacteria, viruses, pollen, additives, certain foods, and others. When a person is first introduced to an antigen, such as a flu virus, the immune system makes an antibody, or protective chemical, to fight off the invader.

How does the body fight off a virus? How HIV/AIDS overwhelms the body. HIV attacks and kills a type of immune system cell known as T lymphocytes. These T cells are crucial for killing other cells in the body that have been infected with germs. Without T cells, other immune system cells, such as antibody-making B cells, can't work properly. If HIV is not treated the number of T cells drops steadily. Eventually, numbers fall to the point that the risk of infection greatly increases. This end-stage is known as AIDS.

It is really a collection of reactions and responses that the body makes to damaged cells or infection. So it is sometimes called the immune response. cells react against invading bacteria or viruses by making proteins called antibodies. The antibody made is different for each different type of germ (bug). The antibody locks onto the surface of the invading bacteria or virus.
