Immunology

Human diseases can be split into two categories:

Damage to the body caused by injury or disease is repaired naturally by the growth and spread of new tissue to replace damaged ones. The precise way in which the replace process works varies according to the type of tissue and the size and nature of the damage.
The first step in healing is the formation of a blood clot, sealing the cut and stopping the bleeding. A scar of dried blood forms on the surface of the skin and protects the new tissue forming beneath it. Fibrous tissue builds up in the wound, new cells and blood vessels grow in the gap, and a week later there is no visible indication of the injury. However this is not the case in all injuries, in more complicated cases the wound is replaced by fibrous scar tissue. Eg. Lungs, Kidneys etc.

HOW THE BODY FIGHTS INFECTION

Viruses, bacteria, fungi, worms and other parasites, which enter the body through the skin, nose, mouth or other openings of the body, cause infectious diseases. The body has various barriers against such invasions and they are as follows:

What is the Immune System?

The purpose of the immune system is to keep infectious microorganisms, such as certain bacteria, viruses, and fungi, out of the body, and to destroy any infectious microorganisms that do invade the body. The immune system is made up of a complex and vital network of cells and organs that protect the body from infection.

The organs involved with the immune system are called the lymphoid organs, which affect growth, development, and the release of lymphocytes (a certain type of white blood cell). The blood vessels and lymphatic vessels are important parts of the lymphoid organs, because they carry the lymphocytes to and from different areas in the body. Each lymphoid organ plays a role in the production and activation of lymphocytes. Lymphoid organs include:

What are lymphocytes?

Lymphocytes - a type of infection-fighting white blood cell - are vital to an effective immune system. Lymphocytes "patrol" the body for infectious microorganisms.

How are lymphocytes formed?

All cells, including immune cells such as lymphocytes, are produced in the bone marrow (the soft, fatty tissue found in bone cavities). Certain cells will become part of the group of lymphocytes, while others will become part of another type of immune cells known as phagocytes. Once the lymphocytes are initially formed, some will continue to mature in the bone marrow and become "B" cells. Other lymphocytes will finish their maturation in the thymus and become "T" cells. B and T cells are the two major groups of lymphocytes which recognize and attack infectious microorganisms.
Once mature, some lymphocytes will be housed in the lymphoid organs, while others will travel continuously around the body through the lymphatic vessels and bloodstream.

How do lymphocytes fight infection?

Although each type of lymphocyte fights infection differently, the goal of protecting the body from infection remains the same. The B cells actually produce specific antibodies to specific infectious microorganisms, while T cells kill infectious microorganisms by killing the body cells that are affected. In addition, T cells release chemicals, called lymphokines, which trigger an immune response to combat cancer or a virus, for example.
Other types of white blood cells, such as phagocytes (engulfing cells) and cytotoxic cells (natural killer cells), actually kill the infectious microorganism by "devouring" it.

What is natural and acquired immunity?

The immune system has many different responsibilities. Not only does the immune system provide protection from infection through natural barriers, but it also adapts itself to provide immunity against infection by "remembering" the infectious microorganism from a previous exposure. The degree and duration of immunity depend on the type and amount of antigen and how it enters the body.

What are disorders of the immune system?

When the immune system does not function properly, it leaves the body susceptible to an array of diseases. Allergies and hypersensitivity to certain substances are considered immune system disorders. In addition, the immune system plays a role in the rejection process of transplanted organs or tissue. Other examples of immune disorders include:

What is an infectious disease?

According to the Centers for Disease Control and Prevention (CDC), an infectious disease is caused by one or more of the following:

Infectious diseases can range from common illnesses, such as the cold, to deadly illnesses, such as AIDS. Depending on the specific illness and country (some countries with poor community hygiene may still experience waterborne transmission of a disease), an infectious disease can spread in some or all of the following ways:

In developed countries, most infections are spread through sexual, airborne, blood-borne, and direct skin contact transmission.

What is the difference between viruses and bacteria?

Viruses and bacteria cause the majority of infections. Viruses cause most colds, flu, coughs, and sore throats. Bacteria cause most ear and sinus infections, strep throat, and urinary tract infections. Both bacteria and viruses can enter the body in many ways, including through inhalation, food, sexual contact, and skin contact.

How do antibiotics work against infections?

Antibiotics can be used to treat bacterial infections. However, antibiotics are ineffective in treating virus-related illnesses. In addition, antibiotics treat specific bacteria and overuse or misuse of antibiotics can lead to drug-resistant bacteria. It is important that antibiotics are taken properly and for the duration of the prescription. If antibiotics are stopped early, the bacteria may develop a resistance to the antibiotics.
