A quick glimpse at the Immune System

The immune system, made up of proteins, special cells, tissues as well as organs normally protects folks from microorganisms and germs every day. In most cases, the given system carries out a great job of keeping folks healthy and preventing infections. However, sometimes issues with the immune system can provoke infection and diseases.

The immune system is solely responsible in the body for defending against infectious organisms as well as other invaders. Via a series of steps dubbed the immune response, the immune system is used to attacking organisms as well as substances, invading body systems and causing diseases.

The immune system includes a complex network of tissues, cells and organs, working together to protect the human body. One of the most crucial cells involved are so called white blood cells, also called dubbed leukocytes, coming in two basic types, which combine to seek out and terminate disease-causing organisms or substances.

Leukocytes are generated or stored in a variety of locations across the body, including the thymus, bone marrow and spleen. Exactly for this reason, they’re dubbed the lymphoid organs. Apart from that, there’re clumps of lymphoid tissue in the body, mostly as lymph nodes, housing the leukocytes.

The leukocytes are used to circulating across the body between the nodes and organs via lymphatic vessels as well as and blood ones. Thus, the immune system functions in a coordinated manner to monitor the body for germs or any other suspicious substances, which might generate problems.

There’re two basic types of leukocytes:

  • Phagocytes: These cells chew up invading organisms.
  • Lymphocytes: They enable the body to remember and also recognize previous invaders and assist the body in destroying them.

A certain number of different cells are considered to be phagocytes. The neutrophil appears to be the most common type, that primarily fights bacteria. If doctors are concerned over a bacterial infection, they might use a blood test to see whether a patient features an increased number of neutrophils triggered by the infection or not. As for other types of phagocytes, they boast their own jobs to make sure that the body adequately responds to a specific type of invader.

The two major kinds of lymphocytes are B lymphocytes and T lymphocytes. They start out in the bone marrow, then stay there and simply mature into B cells. They are also free to leave for the thymus gland, where they can mature into T cells.

The immune system, made up of proteins, special cells, tissues as well as organs normally protects folks from microorganisms and germs every day. In most cases, the given system carries out a great job of keeping folks healthy and preventing infections. However, sometimes issues with the immune system can provoke infection and diseases.
