Understanding White Blood Cells (Leukocytes), Functions, Types and Characteristics

Understanding White Blood Cells (Leukocytes), Functions, Types and Characteristics – This time we will discuss about blood. Blood is an important thing for humans, if you have ever heard that there is such a thing as blood cells.

Understanding White Blood Cells (Leukocytes), Functions, Types and Characteristics

Here we will discuss about white blood cells, let's see.

Definition of White Blood Cells

White blood cells are cells that make up blood components. These cells are also often called leukocytes, this type of blood cell has a nucleus but does not have a fixed cell shape. And this type of blood cell that has a shape in the blood components. Where this type of blood cell is often called a leukocyte. Where white blood cells have a nucleus but do not have permanent cells and do not have color.

Each cubic millimeter in a white blood cell is about 8,000. Where the formation of this type of blood cells occurs in the red marrow of the flat bones, spleen, and lymph nodes. All white blood cells have a life span of about six to eight days.

There are several types of white blood cells in which white blood cells are divided into 5 namely, neutrophils, lymphocytes, monocytes, eosinophils, and also basophils. For more details, let's discuss about white blood cells below.

Functions of Types and Characteristics of White Blood Cells

White blood cells have several types and characteristics and functions for our bodies where some have an important role for more details see below.

1. monocytes

Monocytes are white blood cells that make up about 1% to 3% in our body, which is the second line of defense for our body by infection and bacteria and foreign objects.

So that monocytes are one of the immune systems that do not have granules in cells or granules. The resistance that is carried out against infection and also foreign bodies monocytes can do this by eating their opponents even though they are larger than the monocytes themselves.

In the circulating blood monocytes range from 300 to 500 microliters of blood which can be produced in the human bone marrow so that it is spread throughout the body in within 3 days by entering into certain body tissues that have experienced maturity which then becomes macrophages that have a function for immunity. Where an excess of monocytes is often called monocytosis, or we often find it in parotitis, mononucleosis, herpes zoster, and many others.

Functions of Monocytes

1. Can destroy foreign cells
2. Can lift dead tissue
3. Can kill cancer cells
4. Useful as a scavenger of phagocytosis by neutrophils
5. Can stimulate others to protect the body
6. As a sign of changes in the patient's health with more or less monocytes present in the body

Features of monocytes

1. In this type of blood cells have an amount of about 1 to 10%
2. Have a life time that tends to be longer than neutrophils
3. Has phagocytic properties and is also motile with a round nucleus
4. Monocytes can also move or immigrate very quickly
5. Has the same shape as a bean
6. Has a circulation in the blood ranges from 300 to 500 microliters
7. And also has no fine granules on cells or granules

2. Basophils

Basophils are white blood cells that make up between 0.01 to 0.03% in our body. Many basophils have cytoplasmic granules with two lobes. Basophils are a group of granulocytes that are able to move outward towards certain body tissues.

Basophils can work what if there is an allergy to our body by releasing histamine, and then blood vessels dilate. An increase in the number of basophils will occur when the number of allergies increases. Where the increase in basophils is often also called basophilia.

Functions of Basophils

1. Basophils have a function to react to allergies and reactions to antigens by activating and also releasing histamine which causes inflammation
2. To prevent the occurrence of clots in the blood vessels
3. Can help repair wounds
4. Can enlarge blood vessels

Characteristics of Basophils

1. Has phagocytic properties and is also wet
2. Basophytes sometimes have a blue color
3. Has a U shape and is also speckled
4. Has a diameter between 12 to 15 micrometers
5. Has an amount of 0.01 to 0.03% in blood cells
6. Has coarse granules
7. Has a non-segmented core
8. Basophils are formed in the bone marrow

3. Neutrophil

Neutrophils are white blood cells that make up 50 to 60% in the blood of a group of granulocytes because they have fine granules. And Neutrophils are often called polymorphonuclear cells because their cells have an unusual shape.

As well as having 3 cell nuclei, neutrophils are the first barrier to fight bacteria, viruses and other foreign objects that have a role in the inflammatory process. Neutrophils have phagocytic properties so that neutrophils can attack with respiration that uses various substances containing hydrogen peroxide, oxygen free radicals, and hypochlorite.

Neutrophils are also produced in the bone marrow so that the production of neutrophils is approximately 100 billion neutrophils in a day, and can increase up to ten times if there is severe inflammation strong.

When it leaves the bone marrow, it becomes six stages of morgolis, namely meilocites, metameocytes, non-segment or band neutrophils, and segment neutrophils.

Functions of Neutrophils

1. Responding to microbes
2. As an antibiotic in the body
3. Has a function as an inflammatory process
4. Destroy micro-organisms and foreign objects and then eat them or better known as phagocytosis
5. The body's defense cells to fight infection
6. Can help remove noxious stimuli and can cause cell death or necrosis
7. Creating an area that has a lack of poison

Neutrophil Characteristics

1. Has a cell nucleus
2. Has 50 to 60% in the blood
3. Functions as polymorphonuclear
4. One group of granulocytes
5. Has phagocytic properties
6. The result of the production of neutrophils is approximately 100 billion neutrophils in a day
7. Neutrophils have a size of approximately 8 mm
8. Has a life time of 6 to 20 hours

4. lymphophyte

Lymsophytes are white blood cells that make up 20 to 25% in the body which has the second largest number after neutrophils. And lymphophytes are formed in the bone marrow and also the spleen. Lymphocytes are divided into two small lymphocytes and also large lymphocytes.

Lymphocytes produce about 1 cubic about 8000 cells in white blood. If an increase in lymphocytes occurs, it can cause blood cancer or what is often called leukemia. Lymphocytes are divided into 6, namely B lymphocytes, helper T cells, cytotoxic T cells, memory T cells, and suppressor T cells.

Functions of Lymphocytes

1. Can produce antibodies
2. Can activate the immune system
3. Removes chemicals and can destroy pathogens
4. Protects the body's normal cells
5. Can identify certain pathogens
6. Can turn into antibodies or plasma cells
7. Can fight cancer

Characteristics of Lymphocytes

1. Lymphocytes make up 20 to 25% of all these cells
2. Formed in bone marrow and spleen
3. Nuclear cell one
4. Can't move freely
5. Has a pale blue color
6. Has an oval or round shape
7. Has no granules and is also motile

5. Eosinophils

Eosinophils are white blood cells that make up 7% of these cells and also increase in association with asthma, allergies and hay fever. Eosophils have a diameter of about 10 to 12 micrometers.

And Eosophil is one of a group of granulocytes that have the task of killing parasites within 8 to 12 days. Eosophils have chemical substances such as ribonuclease, histamine lipase and many others.

Functions of Eosinophils

1. Can prevent allergies
2. Can destroy antigen antibody
3. Has a function as a large parasite destroyer
4. Has a role in responding to allergies

Characteristics of Eosinophils

1. Has a nucleus with two lobes
2. Has phagocytic properties and also has acidic properties
3. Sometimes it's red
4. It has a shape similar to a ball and measures about 9 mm
5. Has a diameter of 10 to 12 micrometers
6. Has a life span of 8 to 12 days
7. Formed in the bone marrow
8. Has coarse and dense granules
9. The core is in the middle

That's all the explanation aboutknowledge.com about Understanding White Blood Cells (Leukocytes), Functions, Types and Characteristics, white blood cells have many types and functions for our bodies so we must take care of what is in our body so that it does not cause an increase in white blood cells that can cause blood cancer or leukemia.
