Types of White Blood Cells – Explained Briefly
There are five types of white blood cells: neutrophils, eosinophils, basophils, lymphocytes, and monocytes.
Neutrophils are the most common type of white blood cell and are responsible for fighting bacteria and other infections.
Eosinophils are responsible for attacking parasites and other foreign invaders.
Basophils release histamine and other chemicals that help fight infection.
Lymphocytes are responsible for producing antibodies that fight infection.
Monocytes become macrophages, which are cells that engulf and digest bacteria and other foreign invaders.
Types of Blood Cells:
There are three types of blood cells- red blood cells, white blood cells and platelets.
Red blood cells are responsible for carrying oxygen throughout the body. White blood cells are responsible for fighting infection, and platelets are responsible for clotting blood.
Red Blood Cells
Red blood cells are round, biconcave discs that circulate in the bloodstream. They are about 8 micrometers in diameter and have a lifespan of about 120 days. Their primary function is to transport oxygen from the lungs to the rest of the body. They also remove carbon dioxide from the tissues and transport it back to the lungs.
What are White Blood Cells?
White blood cells (WBCs) are a type of blood cell that defends the body against infection. They are produced in the bone marrow and are found in the blood and lymphatic system. There are several types of WBCs, including neutrophils, lymphocytes, monocytes, and eosinophils. WBCs play a role in the immune response to infection and disease.
Plasma
Plasma is the fourth state of matter, consisting of electrically charged particles (ions) that move freely around a gas. The particles are held together by electromagnetic forces, and the gas is held together by gravity.
Platelets
are mainly responsible for blood clotting. When bleeding occurs, the platelets adhere to the site of injury and release chemicals that activate the clotting process.
: Platelets are mainly responsible for blood clotting. When bleeding occurs, the platelets adhere to the site of injury and release chemicals that activate the clotting process. Normal platelet count : 150,000-450,000/mm3
: 150,000-450,000/mm3 Increased platelet count: A platelet count greater than 450,000/mm3 is considered high.
White Blood Cells Function
White blood cells are cells that help the body fight infection and disease. They are produced in the bone marrow and circulate in the blood. There are several types of white blood cells, including neutrophils, lymphocytes, and monocytes.
White blood cells fight infection by attacking and destroying bacteria and other foreign organisms. They also produce antibodies, which are proteins that help the body fight infection. White blood cells also play a role in the body’s immune response, which is the body’s ability to protect itself from infection and disease.
Types of White Blood Cells and Their Function:
1. Granulocytes: These are the most common type of white blood cell and they are responsible for fighting infection. There are three types of granulocytes: neutrophils, eosinophils, and basophils.
2. Lymphocytes: These cells are responsible for defending the body against infection and cancer. There are two types of lymphocytes: B cells and T cells.
3. Monocytes: These cells are responsible for fighting infection and removing dead cells and debris from the body.
1. Granulocytes:
These are white blood cells that help the body fight infection. They are produced in the bone marrow.
2. Lymphocytes: These are white blood cells that help the body fight infection. They are produced in the bone marrow.
3. Monocytes: These are white blood cells that help the body fight infection. They are produced in the bone marrow.
4. Eosinophils: These are white blood cells that help the body fight infection. They are produced in the bone marrow.
5. Basophils: These are white blood cells that help the body fight infection. They are produced in the bone marrow.
Difference Between Basophils, Eosinophils, and Neutrophils:
Basophils, eosinophils, and neutrophils are all types of white blood cells. Basophils are responsible for releasing histamine, which causes inflammation. Eosinophils are responsible for destroying parasites. Neutrophils are responsible for fighting infection.
2. Lymphocytes:
A. are a type of white blood cell
B. are responsible for fighting infection
C. are produced in the bone marrow
D. are found in the blood and lymphatic system
Lymphocytes are a type of white blood cell that are responsible for fighting infection. They are produced in the bone marrow and are found in the blood and lymphatic system.
Difference Between B Cells and T Cells:
B cells are lymphocytes that mature in the bone marrow and then enter the blood stream. They are responsible for producing antibodies that recognize and bind to specific antigens. T cells are lymphocytes that mature in the thymus. They are responsible for activating the B cells to produce antibodies and for regulating the immune response.
3. Monocytes:
a. are produced in the bone marrow
b. are the largest white blood cells
c. are responsible for fighting infection
d. all of the above
d. all of the above
WBC Normal Range:
4.8-10.8×10^3/ul
What Happens When a Person has a High White Blood Cell Count?
A person with a high white blood cell count is likely experiencing an infection or inflammation.
What Happens When a Person has a Low White Blood Cell Count?
When a person has a low white blood cell count, it means that their body is not able to fight infection as well as it should be. This can lead to a person becoming sick more easily, and may also make them more susceptible to infection-related complications.
