Outline the maturation of leukocytes. what is the main function of each of the mature leukocytes?

The leukocytes are the main defenses of our body.

Explanation:

From the mother cell it will be a differentiation, from the mother cell to be a mother cell hematopoietic, this will turn into a lymphatic mother cell until it will be 3 different kinds of lymphocytes, the B, T and NK.

Lymphocyte B is the responsible for the inmune system based in antibodies and antigens, due to specific proteins.

Lymphocytes T, are the ones that come from the mother cell of the bone marrow. They are the responsible for the immunity against some illness like cancer.

Lymphocytes NK (natural killer) are the responsible for  killing bad cells (like cancer cells) because they "eat" them in a phagocytosis  process.

The maturation of leukocytes arise from hemopoietic stem cells in the bone narrow. They are involved in pathogen recognition.

The main function of mature leukocytes is to defend the body against diseases.

Explanation:

Pathogen is any organism or substance, specially a microorganism capable of causing diseases. For example: virus, bacteria, protozoa or fungi. The microorganism will only be considered pathogenic when its population has grown enough to cause a disease.

The leukocytes are a major component of  the body's defenses.

They have a nucleus, are capable of motility and defend the body against infections and diseases by ingesting foreign materials and cellular debris, by destroiying infectious agents and cancer cells, or by producing antibodies.

A healthy adult human has between 4.500 and 11.000 white blood cells per cubic millimetre of blood. Variations on the amount can occur during the day.

An abnormal increase in white cell number is known as leukocytosis, whereas an abnormal decrease in number is known as leukopenia.

The count may decrease in response to certain types of infections or drugs or in association with certain conditions, such as chronic diseases like anemia and anaphylaxis.
