Hi, this is about tampons it is for girls only so enjoy reading.A tampon is a mass of cotton or rayon; or a mixture of the two inserted into a body cavity or wound to absorb bodily fluid. The most common type in daily use (and the topic of the remainder of this article) is disposable and designed to be inserted into the vagina during menstruation to absorb the flow of blood. Several countries—including the United States, under the banner of the Food and Drug Administration (FDA)—regulate tampons as medical devices.

History
The ancient Egyptians invented the first disposable tampons made from softened papyrus.[citation needed] The ancient Greeks created tampons made from lint wrapped around a small piece of wood, recorded in writing by Hippocrates in the fifth century B.C.[citation needed] Physicians in the medieval Islamic world also described the use of tampons, often for contraceptive purposes.[1] Other materials used for the first tampons have included: wool, paper, vegetable fibers, sponges, grass, and later cotton.
As a medical device, the tampon, (from the French for plug, or stopper[2]) has been around since the 19th century, when antiseptic cotton tampons treated with salicylates were used to stop the bleeding from bullet wounds,[3] and there have been reports of modern menstrual tampons being used for the same purpose by soldiers in the Iraq War.[4]
The applicator tampon with removal cord was invented in 1929 and submitted for patent[5] in 1931 by Dr. Earle Haas, who hailed from Denver, Colorado. Dr. Hass later sold the patent of the applicator tampon to Gertrude Tendrich, who founded the Tampax Company for the mass production of the lengthways expanding tampon.
It is documented that gynecologist Dr. Judith Esser-Mittag developed, during her studies on the female anatomy, the digital design of tampon. In the late 1940’s, Dr. Carl Hahn, together with Heinz Mittag, worked on the mass production of such a tampon. Dr. Hahn sold his Company which included the digital style tampon range to Johnson and Johnson in 1974. The first fully [edit] Design and packaging
Tampons come in various sizes, which are related to their absorbency ratings and packaging. The outward appearance of a tampon is similar for all brands, but their absorbency varies. The two main differences are in the way the tampon expands when in use; for example applicator tampons such as Tampax tampons and Natracare tampons will expand axially (increase in length), while OB, Natracare and Lil-lets digital tampons will expand radially (increase in diameter). All tampons have a cord for removal and some have an additional outer cover to aid insertion and withdrawal. Some women prefer to use a tampon which is contained within an applicator to further aid insertion. The majority of tampons sold are made of rayon, or a blend of rayon and cotton. Organic cotton tampons are made from only 100% cotton. Tampons are sold individually wrapped to keep them clean, and because the vagina is not a sterile body-cavity, and for the vast majority of women contains “good bacteria”, there is no need for any menstrual device to be sterilized.
Tampon applicators may be made of plastic or cardboard, and are similar in design to a syringe. The applicator consists of two tubes an ‘outer’ and ‘inner’. The ‘outer’ tube has a smooth surface to aid insertion and sometimes comes with a rounded end that is petalled.
The tampon itself sits inside the ‘outer’ tube, near the open end. The ‘inner’ tube is encased inside the ‘outer’ tube and held in place by a locking mechanism. The ‘outer’ tube is inserted into the vagina, then the ‘inner’ tube is pushed into the outer tube (typically using a finger) pushing the tampon through and into the vagina.
Digital or non-applicator tampons are tampons sold without applicators; these are simply unwrapped and pushed into the vagina with the fingers.certified organic, 100% cotton tampons were developed by Natracare in the early 1990s

the human body
Hi,we are talking about human body. Human anatomy, which, with physiology and biochemistry, is a complementary basic medical science is primarily the scientific study of the morphology of the adult human body.[1] Anatomy is subdivided into gross anatomy and microscopic anatomy.[1] Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision.[1] Microscopic anatomy is the study of minute anatomical structures assisted with microscopes, which includes histology (the study of the organization of tissues),[1] and cytology (the study of cells). Anatomy, physiology (the study of function) and biochemistry (the study of the chemistry of living structures) are complementary basic medical sciences which are usually taught together (or in tandem).
In some of its facets human anatomy is closely related to embryology, comparative anatomy and comparative embryology,[1] through common roots in evolution; for example, much of the human body maintains the ancient segmental pattern that is present in all vertebrates with basic units being repeated, which is particularly obvious in the vertebral column and in the ribcage, and can be traced from very early embryos.
The human body consists of biological systems, that consist of organs, that consist of tissues, that consist of cells and connective tissue.
The history of anatomy has been characterized, over a long period of time, by a continually developing understanding of the functions of organs and structures in the body. Methods have also advanced dramatically, advancing from examination of animals through dissection of preserved cadavers (dead human bodies) to technologically complex techniques developed in the 20th century.

Study
A full articulated human skeleton used in education
Generally, physicians, dentists, physiotherapists, nurses, paramedics, radiographers, artists, and students of certain biological sciences, learn gross anatomy and microscopic anatomy from anatomical models, skeletons, textbooks, diagrams, photographs, lectures, and tutorials. The study of microscopic anatomy (or histology) can be aided by practical experience examining histological preparations (or slides) under a microscope; and in addition, medical and dental students generally also learn anatomy with practical experience of dissection and inspection of cadavers (dead human bodies). A thorough working knowledge of anatomy is required by all medical doctors, especially surgeons, and doctors working in some diagnostic specialities, such as histopathology and radiology.
Human anatomy, physiology, and biochemistry are basic medical sciences, which are generally taught to medical students in their first year at medical school. Human anatomy can be taught regionally or systemically;[1] that is, respectively, studying anatomy by bodily regions such as the head and chest, or studying by specific systems, such as the nervous or respiratory systems. The major anatomy textbook, Gray's Anatomy, has recently been reorganized from a systems format to a regional format,[2][3] in line with modern teaching methods.

Influenza A(H1N1) virus is a subtype of influenzavirus A and the most common cause of influenza (flu) in humans. Some strains of H1N1 are endemic in humans and cause a small fraction of all influenza-like illness and a large fraction of all seasonal influenza. H1N1 strains caused roughly half of all human flu infections in 2006.[1] Other strains of H1N1 are endemic in pigs (swine influenza) and in birds (avian influenza).
In June 2009, World Health Organization declared that flu due to a new strain of swine-origin H1N1 was responsible for the 2009 flu pandemic. This strain is commonly called "swine flu" by the public media.[edit] Nomenclature
The various types of influenza viruses in humans. Solid squares show the appearance of a new strain, causing recurring influenza pandemics. Broken lines indicate uncertain strain identifications.[2]
Influenza A virus strains are categorized according to two proteins found on the surface of the virus: hemagglutinin (H) and neuraminidase (N). All influenza A viruses contain hemagglutinin and neuraminidase, but the structures of these proteins differ from strain to strain, due to rapid genetic mutation in the viral genome.
Influenza A virus strains are assigned an H number and an N number based on which forms of these two proteins the strain contains. There are 16 H and 9 N subtypes known in birds, but only H 1, 2 and 3, and N 1 and 2 are commonly found in humans.
Spanish flu
Main article: 1918 flu pandemic
The Spanish flu, also known as La Gripe EspaƱola, or La Pesadilla, was an unusually severe and deadly strain of avian influenza, a viral infectious disease, that killed some 50 million to 100 million people worldwide over about a year in 1918 and 1919. It is thought to be one of the most deadly pandemics in human history. It was caused by the H1N1 type of influenza virus.[4]
The 1918 flu caused an unusual number of deaths, this might have been due to it causing a cytokine storm in the body.[5][6] (The recent epidemic of bird flu, also an Influenza A virus, had a similar effect.)[7] The Spanish flu virus infected lung cells, leading to overstimulation of the immune system via release of cytokines into the lung tissue. This leads to extensive leukocyte migration towards the lungs, causing destruction of lung tissue and secretion of liquid into the organ. This makes it difficult for the patient to breathe. In contrast to other pandemics, which mostly kill the old and the very young, the 1918 pandemic killed unusual numbers of young adults, which may have been due to their healthy immune systems being able to mount a very strong and damaging response to the infection.[2]
The term "Spanish" flu was coined because Spain was at the time the only European country where the press were printing reports of the outbreak, which had killed thousands in the armies fighting the First World War. Other countries suppressed the news in order to protect morale.[8]
Influenza A virus subtype H2N2#Russian flu for the 1889–1890 Russian flu
The more recent Russian flu was a 1977–1978 flu epidemic caused by strain Influenza A/USSR/90/77 (H1N1). It infected mostly children and young adults under 23 because a similar strain was prevalent in 1947–57, causing most adults to have substantial immunity. Some have called it a flu pandemic, but because it only affected the young it is not considered a true pandemic. The virus was included in the 1978–1979 influenza vaccine.[9][10][11][12]
2009 A(H1N1) pandemic
Illustration of influenza antigenic shift.
Main article: 2009 flu pandemic
In the 2009 flu pandemic, the virus isolated from patients in the United States was found to be made up of genetic elements from four different flu viruses – North American Mexican influenza, North American avian influenza, human influenza, and swine influenza virus typically found in Asia and Europe – "an unusually mongrelised mix of genetic sequences."[13] This new strain appears to be a result of reassortment of human influenza and swine influenza viruses, in all four different strains of subtype H1N1.
Preliminary genetic characterization found that the hemagglutinin (HA) gene was similar to that of swine flu viruses present in U.S. pigs since 1999, but the neuraminidase (NA) and matrix protein (M) genes resembled versions present in European swine flu isolates. The six genes from American swine flu are themselves mixtures of swine flu, bird flu, and human flu viruses.[14] While viruses with this genetic makeup had not previously been found to be circulating in humans or pigs, there is no formal national surveillance system to determine what viruses are circulating in pigs in the U.S.[15]
On June 11, 2009, the WHO declared an H1N1 pandemic, moving the alert level to phase 6, marking the first global pandemic since the 1968 Hong Kong flu.[16]
