White blood cells are the defense mechanism of the body. When foreign entities enter the body, the white blood cells attack it to remove it from the body.
they either engulf them (swallow them) or place anti-bodys over the antigens to kill them
phagocytosis
antibody production
The antibodies help the white blood cells to detect and identify foreign particles, by attaching to the anti genes.
phagocytosis
White blood cells use phagocytosis to remove foreign particles from the blood stream. These cells will literally engulf foreign particles that are the same size as itself. There are two types of white blood cells which act as phagocytes: macrophages and polymorphic leucocytes. To be phagocytosed, particles need to bind to the receptors on the phagocyte. Then the particle is engulfed and absorbed.
They fight infections, and protect our body from foreign particles.
White blood cells use phagocytosis to get rid of foreign particles in the blood. Phagocytes are cells that protect the body by ingesting harmful bacteria, foreign particles, and dying cells.
White blood cells
White blood cells: Destroys foreign materials. Red blood cells: transport oxygen throughout the body.
Red blood cells carry oxygen and carbon dioxide. White Blood Cells fight foreign materials in the body.
White blood cells are a part of the immune system, they attack and destroy foreign entities in the body. White bloods cells have a nucleus, whereas red blood cells do not.
White blood cells, because they are actually a cell of the immune system and they defend the body against infectious diseases and foreign materials. When white blood cells are fighting against a disease or foreign material, their numbers increase until the material is gone.
White-Blood Cells. Either Pathogens, or Lymphocytes.
White blood cells attach to foreign objects and also help fight disease and sickness.
