What are anti bodies and antigen?

The antigen is the foreign "invader" in the body. The antibody is a tiny "Y" shaped protein that is chemically attracted to a specific antigen; binding to it and thereby marking it for destruction by a white blood cell.


What type of cell makes blood cells?

antigen


What is hepatitis virus tests?

These tests are based primarily on antigen-antibody reactions--an antigen being a protein foreign to the body, and an antibody another type of protein manufactured by lymphocytes (a type of white blood cell) to neutralize the antigen.


What Red blood cell antigen named after the rhesus monkey?

The red blood cell antigen named after the rhesus monkey is the Rh factor or Rh antigen. It is an important antigen in blood transfusions and plays a role in hemolytic diseases of the newborn when an Rh-negative mother carries an Rh-positive fetus.


What does the body do when an antigen enters the body?

when a antigen enters the body then the body would send antibodies to get rid of them. The antibody doesn't get rid of the antigen they tag it by binding to it so that a cell..a white blood cell can come and destroy by phagi.


What happence when an antigen on a red blood cell comes in contact with the antibody designed to seek it out?

The antibody is killed off, and the antigen spreads


What doe the word heterozygous mean in terms of red cell antigen typing?

Heterozygous in red cell antigen typing means that an individual possesses two different alleles for a specific blood group antigen on their red blood cells. This is in contrast to homozygous, where an individual carries two identical alleles for a particular blood group antigen.


What does a white blood cell have that a red blood cell doesn't?

The white blood cell has nucleus that red blood cell does not


What is the difference between the red blood cell and the nerve cell?

the nerve cell is the white cell and it is white but it doesnt care as much blood as the red blood cell does that's the difference. Also, the nerve cell is the white cell and it is white but the red blood carries blood. Wait, I think the nerve cell is the white cell is white. White Cell=Nerve Cell*white. Cell=Nerve/White =;)


What group does the phagocytic antigen-presenting cell belong to?

Phagocytic antigen-presenting cells belong to the group of immune cells known as leukocytes or white blood cells. These cells engulf and digest pathogens and then present pieces of them to other immune cells to activate an immune response. Common phagocytic antigen-presenting cells include macrophages, dendritic cells, and some types of white blood cells.


What produces antibodies to remove foreign invaders?

Antibodies are produced in a White blood cell called a plasma cell. The antibody is made for a specific type of pathogen which it recognises by it's antigen. The antibody will link on to the pathogen and either destroy it or hold on to it until another White blood cell will come and ingest (eat) it.


To what do antibodies respond?

Antibodies are secreted by a special group of white blood cells called lymphocytes. Each type of cell (including bacteria) has a unique protein on its cell membrane - an antigen. If a lymphocyte does not recognise a particular antigen, it will assume that the cell (or bacterium) is foreign and hostile. This is what antibodies respond to - the stimulus as the result of an unfamiliar cell. The antibodies attach to the antigens and kill the cell, or bacterium.
