Leukocytes are a type of white blood cell that play an essential role in maintaining the body’s immune system. Leukocytes are responsible for recognizing foreign substances and protecting the body from infections and other harmful invaders.

There are five main types of leukocytes: neutrophils, basophils, eosinophils, monocytes, and lymphocytes. Each type has its own specific functions and all work together to protect the body from harm.

Neutrophils are the most abundant type of leukocyte and are the main type of white blood cell responsible for fighting bacterial infections. Basophils are another type of leukocyte that help the body respond to allergic reactions and help fight certain types of parasites.

Eosinophils are another type of leukocyte that help protect the body from parasites and help fight allergies. Monocytes are a type of leukocyte that helps to transport nutrients to other cells and helps to break down bacteria and other foreign substances. Finally, lymphocytes are a type of leukocyte that help fight viruses and cancer cells.

The leukocyte that is not correctly matched with its function is basophils. Basophils are not responsible for fighting bacterial infections, but rather help to respond to allergic reactions and fight certain types of parasites. They are not the main leukocyte responsible for combating bacterial infections, as that is the job of neutrophils.

In summary, the leukocyte that is not correctly matched with its function is basophils. Basophils are responsible for responding to allergic reactions and helping fight certain types of parasites, while neutrophils are the main leukocyte responsible for fighting bacterial infections. All five types of leukocytes work together to protect the body from harm and keep the body healthy.
