Full Form of WEF:- WEF stands for World Economic Forum. It is a non-profit foundation of Switzerland. It is located in Cologny, Geneva. It is an independent international organization committed to benefit the world by engaging the business, political, academic and other leaders of society to shape global, regional and industry agendas.
Formerly, it was known as “European Management Forum” which was founded in 1971, later, it has changed its name as “World Economic Forum” in 1987.
ii) WEF: With Effect From
WEF stands for With Effect From. It is used to represent the starting date of something. For example: If you are owner of a restaurant and you want to increase the prices of every item after a specific date due to increasing rates of vegetables and grains. So, you have to put this on a notice like this:
“Due to increasing rates of vegetables and other grains the restaurant would not be able to serve at former rates. So the management has decided to revise their menu and rate card w.e.f 01/01/2016”.
“With Effect From” is used to represent the starting date of something. For example : If we want to say ‘due to financial distress, the company would not be able to pay bonus to their workers from next financial year 2015’. So we could write :- “due to financial distress, the company would not be able to pay bonus to their workers, w.e.f. 01/04/2015.”

Full Form of WBC: WBC stands for White Blood Cell. It is also called leukocyte or white blood corpuscle. It is a cellular component of the blood. It has a nucleus but does not have hemoglobin like RBCs (red blood cells). Its main role is to protect the body from infections and diseases, e.g. it produces antibodies to destroy the infectious agents like bacteria, viruses, germs, etc.
WBCs are produced in the bone marrow and stored in blood and lymphatic tissue. They are classified into two main groups: granulocytes and agranulocytes (non-granulocytes or non-granular).
As the name indicates, the granulocytes have granules in their cell cytoplasm and have a multi-lobed nucleus. They are of three types: Neutrophils, Eosinophils, and Basophils.
The non-granulocytes do not have granules in their cell cytoplasm and have non-lobular nuclei. They are of two types: Lymphocytes and Monocytes.
The Full form of WBC is White Blood Cell. WBCs are one of the cells the body makes to help fight infections. There are several types of White Blood Cells (leukocytes). The two most common types are the lymphocytes and neutrophils (also called polymorphonuclear leukocytes, “polys” or PMNs).
Lymphocytes are made in lymphoid tissue in the lymph nodes, spleen and thymus gland. There are different kinds of lymphocytes. Lymphocytes identify foreign substances from germs (viruses or bacteria) in the body and produce cells and antibodies that specifically target them. It takes from several days to weeks for lymphocytes to recognize and attack a new foreign substance.
Neutrophils are also major players in the body’s defense against bacterial infections. Neutrophils circulate in the bloodstream and are made in the bone marrow. Neutrophils move out of the blood vessels into the infected tissue to attack the bacteria. The pus in a boil (an abscess) is made up largely of neutrophils.
The White Blood Cell count is done by counting the number of White Blood Cells in a sample of blood. A normal WBC is in the range of 4,000 to 11,000 cells per microliter. A low WBC is called leukopenia. A high WBC is termed as leukocytosis.
What does WBC mean?
“White Blood Cell (WBC) are cells of the immune system involved in defending the body against both infectious disease and foreign materials. Whenever a germ or infection enters the body, the white blood cells snap to attention and race toward the scene of the crime.”
Granulocytes are described as follows:
Neutrophils: They possess a single, multi-lobed nucleus. They are also the most abundant type of WBCs in the blood circulation, e.g. 40-70% of the WBCs in the bloodstream or 2000 to 7500 cells per mm3 in the blood. They are the first line of defence of our body as they quickly reach the site of infection or injury than other types of WBCs.
Neutrophils attach themselves to the wall of blood vessels in order to block the entry of germs into the blood through a cut or infection. They are phagocytes as they kill germs thorough phagocytosis, e.g. first they ingest germs then they kill and digest them. They have a chemical in their granules that they release to kill the pathogens. See the image below:
Eosinophils: They have a double-lobed, U-shaped nucleus. They are less abundant WBCs, e.g. they account for less than 8% of the circulating while blood cells (60-400 cells per mm3 of the bloodstream). They particularly fight the parasitic infections and allergies. Eosinophils are also phagocytic white blood cells. They have large granules that contain chemicals to destroy the pathogens. Eosinophils are commonly found in the connective tissues of the intestine and stomach. See the image below:
Basophils: Basophils are the least abundant type of the white blood cells, e.g. they account for less than 1 to 2 percent of leukocytes in the bloodstream. Like other granulocytes, they also have multi-lobed nucleus and granules in their cytoplasm. They have histamines and heparin in their granules. Heparin thins the blood and prevents blood clotting. Histamine dilates the blood vessels that promotes blood flow and helps white blood cells quickly reach the site of injury or infection. These cells have surface receptors that bind allergy-specific antibodies. When these antibodies encounter a triggering substance, the cells release histamine to initiate body’s allergic response. See the image below:
Agranulocytes are described as follows:
Lymphocytes: They are small, round cells that contain a large nucleus and a small amount of cytoplasm. They are the second most abundant type of WBCs in the bloodstream, e.g. 20 to 40 percent of all white blood cells (1300 to 1400 lymphocytes per mm3 of the blood). They are mostly found in lymphatic tissues including the spleen, tonsils and lymph nodes. Lymphocytes are mainly of two types: B lymphocytes and T lymphocytes.
B lymphocytes: These cells produce antibodies that bind to infected cells or microbes. It neutralizes the infected microbes or marks them out for attack by T lymphocytes.
T lymphocytes: These cells help recognize infectious invaders and activate other types of WBCs. Cytotoxic T cells and Natural Killer Cells are also the types of T lymphocytes that destroy abnormal cells like cancer cells, virus-infected cells etc. See the image below:
Monocytes: They are the largest type of WBCs and usually account for 1 to 10 % of WBCs (leukocytes) in the bloodstream. They have few granules in their cytoplasm and their nucleus may be kidney or bean shaped. They are versatile cells as they differentiate into macrophages when they enter into body tissues from the bloodstream. The macrophages engulf and kill infectious organisms, particularly bacteria. They also release signaling chemicals to attract and send the other WBCs to the site of infection. They also help T cells to respond to infections. See the image below:
