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.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
