Immune System

They engulf it! When you get a cut, your bloodvessels dialate and the white blood cells (phagocytes) will leak from the nearest blood vessels and eat the bacteria near the cut.

i think it has to do with innate immunity or imflammatory response

Alternative Names Blood poisoning; Bacteremia with sepsis Definition Return to top Septicemia is the presence of bacteria in the blood (bacteremia) and is often associated with severe disease. Causes Return to top Septicemia is a serious, life-threatening infection that gets worse very quickly. It can arise from infections throughout the body, including infections in the lungs, abdomen, and urinary tract. It may come before or at the same time as infections of the bone (osteomyelitis), central nervous system (meningitis), or other tissues. Symptoms Return to top Septicemia can begin with spiking fevers, chills, rapid breathing, and rapid heart rate. The person looks very ill. The symptoms rapidly progress to shock with decreased body temperature (hypothermia), falling blood pressure, confusion or other changes in mental status, and blood clotting problems that lead to a specific type of red spots on the skin (petechiae and ecchymosis). There may be decreased or no urine output.

macrophages, killer T cells, helper T cells, and B cells

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.

the antigen must bind to the receptor

Think the process you mean is called phagocytosis.

some students like to study. apex

or

Some of my friends are funny.

e

Laced along the lymphatic routes-with clusters in the neck, armpits, abdomen, etc.

It is called a "killer" T-cell

Eventually, yes.

You asked! T cells belong to a group of white blood cess known as lymphocytes and play a central role in cell-mediated immunity. They can be distinguised from other lymphocyte types, such as B cells and NK cells by the presence of a special receptor on their cell surface that is called the T cell receptor (TCR). The 'T' in T cell stands for thymus since it is the principal organ, found dircetly behind the top of the sternum, for their development. Links to the virus that causes AIDS, HTLV-III. Human T-lymphotropic virus, type III.

Thymosin, from the Thymus gland. Erik

An allergic reaction i believe.

An organ of the lymphatic system, the spleen filters blood and destroys old blood cells by sending them to the liver and elsewhere. The spleen also removes foreign matter such as bacteria and produces lymphocytes, cells that are essential for immunity. In humans, the spleen also stores blood to meet additional demands.

If part of the spleen is removed, the spleen can sometimes regenerate.

myeloid stem cells

Because the virus can enter your body when someone sneezes on you...... i just made that up lol

deffo not right. only serious answers please!

If im correct, helper t-cells activate: b-cells that mark viruses and make them stick together, killer t-cells --which attack macrophages and infected cells, and memory b-cells, which remember how to stop viruses, this i believe is called active immunity

It usually involves the recognition and destruction of pathogens

Phages are also known as bacteriophages which are viruses. They are specifically viruses that attack bacteria. Depending on the species, some viruses incorporate their DNA in to the host's genome. These viruses are known as proviruses because they can go through the lysogenic cycle.

When mixed with an immunogen, it enhances the immune response against the immunogen

White blood cells

A positive HBs antibody titer indicates that an individual has developed antibodies against the hepatitis B virus, typically as a result of vaccination or past infection. This suggests that the person has immunity to hepatitis B and is less likely to contract the virus. It is an important marker for assessing immunity status in individuals, especially those at risk for hepatitis B exposure.

3 types: Dendritic cells, B cells and CD4+ T cells.
