White blood cell how do they fight off infections?

Answer 1

If an infection occurs and bacteria enters your body the white blood cells will produce antibodies to cover them and clump them together, then more white blood cells will engulf them and digest them. A lot of the white blood cells will then die but a few will stay alive as memory cells and if that bacteria enters again they will multipy and fight it before any harm id done. Platelets in the blood will also seal the wound that has been made to prevent any further dirt and bacteria from entering the body.Once you have had a disease the antibodies are produced much quicker the next time you catch the same infection and your body also has some immunity to it.hello people of earth

Answer 2

White blood cells do not "make things". Being proteins themselves they lack the cellular organelles to produce anything. The White blood cells merely bind to the bacteria or virus and denature it.

Answer 3

They engulf the infection (bacteria or virus). Inside it are enzymes that break the harmful substance down and make it safe for the body. From there, the cell excretes it as waste and the body gets rid of it.

Answer 4

When bacteria enters the body due to an infection, a type of white blood cells called phagocytes will surrounds and clumps the foreign bacteria together. They will then engulf the bacteria and digest them. One of the phagocytes would regurgitate parts of the ingested material of the bacteria back to its surface. This material is then offered to another white blood cells called lymphocytes. This is so that the lymphocytes can keep a record of the bacteria so that when they enter the body again, the white blood cells can attack before more harm is done. This is important for the body can build immunity.

Answer 5

If an infection occurs and bacteria enters your body the white blood cells will eat the bacteria or produce antibodies to fight them.Platelets in the blood will also seal the wound that has been made to prevent any further dirt and bacteria from entering the body.Once you have had a disease the antibodies are produced much quicker the next time you catch the same infection and your body also has some immunity to it.

Answer 6

White blood cells are a very important part of the immune system. There are many different types of white blood cells; some (B cells) are responsible for the production of antibodies, others (such as macrophages) act as phagocytes that gather up and digest foreign material and cell debris.
