Each of the different types of immune cell plays a different role in the body; some work on bacteria, & others on viruses. The major divisions are the innate immune system & the adaptive immune system. The innate system is the first line of defence: the cells are 'always on patrol', so can act fast; but they're non-specific, which means that though they'll always have a good shot at dealing with the invading pathogen, but may not succeed; they also carry no memory, so will be no more or less successful the next time they encounter the same pathogen. The major groups of cells in this system are leukocytes, granulocytes, monocytes and natural killer cells (the ones that 'go wrong' in MS), and each one works in a slightly different way, or works on a different kind of pathogen. The adaptive immune system is much slower to get going, but once it does, it's highly specific in its action & tends to be very successful. These cells analyse the pathogen and then produce immunoglobulins - antibodies tailored to deal with that one type of pathogen. Adaptive immune cells carry a memory of every pathogen they've ever encountered, which means that they'll be far quicker at reacting should they meet the same one a second time. The major cells in this system are B & T lymphocytes.

What protects the body from bacteria?
An organism's immune system protects it from harmful bacteria and other organisms. In terms of the Human immune system, this includes leukocytes (white blood cells of various types) and the various parts of the lymphatic system.
Which cells help you get over a cold?
Cells from the immune system. There are several different types of cells that work with other cells in the immune system to clear viruses from your body so you can get over a viral infection such as a cold. Antibodies are produced by the immune system to target the specific virus(es) you have and directly block them from attaching to the cells that the virus affects in your body. Influenza viruses attach to mucous tissues, such as in your nose, mouth, GI system, and eyes.
What are the differences in the DNA in different types of human body cells?
human body system
List the different types of white blood cells and describe their role in the immune system?
Neutrophils, monocytes, lymphocytes, eosinophils and basophils.
Does meiosis or mitosis occur when the immune system produces armies of defensive white blood cells?
Meiosis and mitosis are different types of cellular reproductions. Meiosis is sexual but mitosis is asexual reproduction. Meiosis and mitosis continue to occur when the immune system produces white blood cells.
Which types of T cells are a critical component of the immune system because it stimulates and enhances the activity of other components of the immune system?
T -helper cells

The four main types of immune system cells are?
macrophages, killer T cells, helper T cells, and B cells
What cell types function in the immune system?
The immune system is generally split into two branches the innate and adaptive immune systems. The innate side, which responds quickly to tissue injury and infection, is made up of proteins found in the blood and cells. These cells are nuetrophils, eosinophils, basophils, mast cells, macrophages and dendritic cells. Recent work has also shown that other cells types not normally thought of as being "immune cells" such as epithelial cells have important immune functions. The cells of the adaptive immune response are those that respond to infections much later and are responsible for protection from repeated infections. These include T cells and B cells. These cells will be turned on by the innate immune system, then divide and attack whatever they are specific for.

What do lymphocytes do in the human body?
Lymphocytes are a type of small white blood cell present in the human immune system. These small cells play a very large and important role in fighting diseases in the human body. There are basically two types of lymphocyte cells: B-cells and T-cells. B-cells are responsible for creating antibodies that attack bacteria, infectious microorganisms, and other foreign matter. T-cells have the job of fighting the bodies OWN cells that have been taken over by viruses or cancerous cells (malignancy). The absence of lymphocytes in the human immune system allow our bodies to become more susceptible to infections and disease and weakens immune response.
Can a virus destroy the immune system?
HIV targets CD4+ cells in your immune system, and uses them for factories of reporduction. The CD4+ lymphocyte is the most potent killer in your immune system. By killing off these CD4+ cells, HIV can effectively render your immune system useless and leave you susceptible to many different types of infections that can be fatal.
What are the differences in the DNA in different types of human body cells?
human body system
Does meiosis occur when the immune system produces B and T cells?
B and T cells are both types of white blood cells. When the immune system produces them it is actually mitosis that occurs rather than meiosis. The are produced within the bone marrow.
What are the parts that work together in the immune system?
The bone marrow, the lymph nodes, the spleen, and the thymus are the organs that are part of the immune system, all of which work together to produce the different types of white blood cells which keep you alive.
Protects the body destroys bacteria and tumor cells?
T cells are made in the red bone marrow but specialize into t cells outside the marrow in the thymus, hence the T in Tcells. two types of t cells are cytotoxic effector cells and helper t cells. think of cytotoxic t cells as the drunk guy in the bar that wants to fight everyone (and is a good fighter by the way) and the helper t cells are the friends who show him who to fight and provides him with the weapons to fight. CTC can attach to and destroy cells carrying antigens Helper T cells 1. present antigen to CE cells and plasma B cells to activate them into action and 2. produe powerful immune protein called cytokins which can stimulate the lymphocyte cell disvision.
How does the immune system fights infections?
The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. The cells involved are white blood cells, or leukocytes, which come in two basic types that combine to seek out and destroy disease-causing organisms or substances.
