	~~'''~~White blood cells''' (also called '''leukocytes''' or '''leucocytes''') are the cells of the [[immune system]] that are involved in protecting the body against both infectious disease and foreign invaders. All white blood cells are produced and derived from multipotent cells in the [[bone marrow]] known as [[hematopoietic stem cells]]. Leukocytes are found throughout the body, including the blood and lymphatic system.		==White==

	~~==Types~~ of ~~White Blood Cells==~~		[[File:Paintings_from_the_Chauvet_cave_(museum_replica).jpg\|thumb\|right\|Replica of paintings from the Chauvet cave, showcasing the use of white.]]
	~~There are five main types~~ of white ~~blood cells, which can be divided into two main categories: granulocytes and agranulocytes~~.

	* '''[[Granulocytes]]''': These cells contain granules in their cytoplasm and ~~include [[neutrophils]]~~, ~~[[eosinophils]]~~, and ~~[[basophils]]~~.		White is the lightest color and is achromatic (having no hue). It is the color of fresh snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light.
	* '''[[Agranulocytes]]''': These cells do not contain granules in their cytoplasm and ~~include [[lymphocytes]]~~ and ~~[[monocytes]]~~.

	==~~Function of White Blood Cells~~==		==History and Symbolism==
	The primary function of white blood cells is to fight infection. They do this by attacking and destroying the organisms that cause disease. White blood cells also play a role in the immune response, inflammation, and allergic reactions.

	==White ~~Blood Cell Count==~~		White has been a significant color in art and culture throughout history. In ancient Egypt, white was associated with purity and sacredness. The [[File:Ägyptischer_Maler_um_1360_v._Chr._001.jpg\|thumb\|left\|Ancient Egyptian painting using white.]] Egyptians used white in their art to depict the sacred and the divine.
	~~A '''~~[[white ~~blood cell count~~]]~~''' is a test that measures the number of~~ white ~~blood cells in your body. This test is often included with a complete blood count (CBC). The normal number of WBCs~~ in the ~~blood is 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 x 109/L)~~.

	~~==See Also==~~		In ancient Rome, white was worn by the [[Chief Vestal\|Vestal Virgins]] as a symbol of purity. The [[File:Chief_Vestal.jpg\|thumb\|right\|Chief Vestal wearing white.]] Vestal Virgins were priestesses of Vesta, goddess of the hearth, and their white garments symbolized their commitment to chastity and service.

	~~==References==~~		During the Middle Ages, white was used in religious art to symbolize purity and holiness. The [[File:Sodoma_-_Life_of_St_Benedict,_Scene_31_-_Benedict_Feeds_the_Monk_-_WGA21581.jpg\|thumb\|left\|St. Benedict depicted in white.]] color was often used to depict the robes of saints and angels.

	~~{{stub}}~~		White has been used extensively in art to create contrast and highlight other colors. In the Renaissance, artists like [[Fra Angelico]] used white to depict divine light and purity. The [[File:Transfiguration_by_fra_Angelico_(San_Marco_Cell_6).jpg\|thumb\|right\|Fra Angelico's use of white in the Transfiguration.]] use of white in paintings helped to create a sense of depth and realism.

	~~File:Paintings_from_the_Chauvet_cave_(museum_replica).jpg\|White~~		In the Baroque period, artists like [[Bartolomeo Passarotti]] used white to highlight the features of important figures, such as [[Pope Pius V]]. The [[File:Bartolomeo_Passarotti_Pope_Pius_V.jpg\|thumb\|left\|Pope Pius V depicted in white.]] use of white in clothing and drapery added a sense of grandeur and importance.

In many cultures, white is worn at weddings to symbolize the purity of the bride. In some Eastern cultures, however, white is associated with mourning and funerals.

	~~File:Ghent_Altarpiece_D_-_Adoration_of_the_Lamb_2.jpg\|White~~		In modern times, white is used in design and architecture to create a sense of space and simplicity. It is often used in minimalist designs to convey a sense of calm and order.
