- The main function of the immune system is defense against microbial infection. The other major functions of the immune system depend on a number of major actions that defend us against threats to our health.These actions help our immune system sort out a system of complicated reactions that our body uses every day to defend us from infection and disease.he other major functions of the immune system depend on a number of major actions that defend us against threats to our health.

Spleen Function in Immune System Know about how spleen works in the body from the article below. Advertisement. The immune system is the key unit which protects the body against diseases. A healthy immune system detects pathogens from viruses to parasitic worms, and knows the difference between foreign bodies and the body's own healthy tissue.or the rest of the life, the organ makes white blood cells to fight infection as a part of the lymphatic system. Factors Which May Interfere with Functions of the Spleen. Enlargement of the spleen is one of the most critical spleen problems.

Organs of the Immune System: Your Shield Against Diseases The main organs in the immune system are the bone marrow, thymus, spleen and lymph nodes. Let us have a look at these immune system organs and functions. Bone Marrow: All the cells of the human immune system are formed in the bone marrow, found within the bones, by a process called hematopoiesis.-Cells: The main function of T-cells or T lymphocytes is intensifying immune system responses. They do this by secreting specialized factors, which in turn activate other white blood cells, to fight off infections. T-cells are again subdivided into different types.

The organs involved with the immune system are called the lymphoid organs.They affect growth, development, and the release of lymphocytes (a certain type of white blood cell).he immune system keeps infectious microorganisms, such as bacteria, viruses, and fungi, out of the body. It also destroys any infectious microorganisms that do invade the body.

What are macrophages? Immune and lymphatic system health is necessary for protecting your body from germs and diseases. Known as the body's first line of defense, your immune system and lymphatic system help protect you from bacteria, viruses and fungi that cause disease. Your lymphatic system produces and carries white blood cells containing antibodies that fight off infection.

Immune system How does the immune system protect us from disease? The immune system includes physical barriers, such as the skin and mucous membranes that prevent pathogens from entering the body, and cellular responses, such as circulating macrophages that respond to foreign invaders. Our acquired immune system mounts a specific antibody response when the body is exposed to a foreign invader, and our immune cells attack the invader.

Rabies Rabies is spread when an infected animal scratches or bites another animal or human. Saliva from an infected animal can also transmit rabies if the saliva comes into contact with the mouth, nose, or eyes. Globally, dogs are the most common animal involved.More than 99% of rabies cases in countries where dogs commonly have the disease are caused by dog bites.In the Americas, bat bites are the most common source of rabies infections in humans, and less than 5% of cases are from dogs. Rodents are very rarely infected with rabies.ore than 99% of rabies cases in countries where dogs commonly have the disease are caused by dog bites.

How Does The Immune System Work The cells that contribute to the immune system are mostly derived from the bone marrow. Bone marrow is the soft material in the centre of large bones. It acts like a factory where “stem” cells produce an ongoing supply of blood cells: red blood cells to carry oxygen. platelets to repair leaky blood vessels and.

Stress, Illness and the Immune System The immune system is a collection of billions of cells that travel through the bloodstream. They move in and out of tissues and organs, defending the body against foreign bodies (antigens), such as bacteria, viruses and cancerous cells. There are two types of lymphocytes : B cells-produce antibodies which are released into the fluid surrounding the body’s cells to destroy the invading viruses and bacteria. T cells (see picture opposite) - if the invader gets inside a cell, these (T cells) lock on to the infected cell, multiply and destroy it.

- 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.he antibody locks onto the surface of the invading bacteria or virus. The invader is then marked with the antibody so that the body knows it is dangerous and it can be killed off. Antibodies can also detect and kill damaged cells. The B cells are part of the memory of the immune system.

Immune system The immune system is a system of many biological structures and processes within an organism that protects against disease. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue.he ability of the immune system to respond to pathogens is diminished in both the young and the elderly, with immune responses beginning to decline at around 50 years of age due to immunosenescence. In developed countries, obesity, alcoholism, and drug use are common causes of poor immune function.

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. 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.

The Immune System and Primary Immunodeficiency The immune system is a wonderful collaboration between cells and proteins that work together to provide defense against infection. These cells and proteins do not form a single organ like the heart or liver. Instead, the immune system is dispersed throughout the body to provide rapid responses to infection (Figure 1). Cells travel through the bloodstream or in specialized vessels called lymphatics.

Immune System: Diseases, Disorders & Function The role of the immune system — a collection of structures and processes within the body — is to protect against disease or other potentially damaging foreign bodies.isorders of the immune system can result in autoimmune diseases, inflammatory diseases and cancer, according to the NIH. Immunodeficiency occurs when the immune system is not as strong as normal, resulting in recurring and life-threatening infections, according to the University of Rochester Medical Center.
