Name of Science "anatomy" (humans, animals, plants) is derived from the Greek word "anatemno" - cut, dismember, dissect, and its essence is to study the structure organisms and organisms organs by method autopsy of tissues. This science refers to the biological sciences, united under the term "morphology" (from the Greek. Tohriho - form, logos - teaching).
Morphology (a term coined German poet and scientist Goethe in 1817) is not limited to stating the information on the form and structure of the various parts of the body (normal, abnormal, ugly, etc.) obtained at different teaching levels (macroscopic, microscopic, cellular, molecular etc.). It also clarifies the organs evolution and the whole organism under the influence of various factors (functional, climatic -heohrafichnyh etc.). It must be admitted that the priority of anatomy was very large in the historical birth of many morphological sciences. In the late XIX - early XX centuries the morphology developed its section - evolutionary morphology which aims to study organisms and some organs in ontogeny and phylogeny.
Human anatomy as an independent science for a long time (until the XIX century) remained as descriptive in most cases (arose as descriptive anatomy), that it was limited to only describing, naming and classification of organs and systems. In the Renaissance, and all subsequent days up to now world science was enriched by discoveries that explain not only certain phenomena but also reasons of their occurrence and development. In search of truth, scientists were increasingly go beyond the individual sciences. In other words, there was a process of intensive interpenetration of different disciplines.

Hemophilia is usually an inherited bleeding disorder in which the blood does not clot properly. This can lead to spontaneous bleeding as well as bleeding following injuries or surgery. Blood contains many proteins called clotting factors that can help to stop bleeding. People with hemophilia have low levels of either factor VIII (8) or factor IX (9). The severity of hemophilia that a person has is determined by the amount of factor in the blood. The lower the amount of the factor, the more likely it is that bleeding will occur which can lead to serious health problems.
In rare cases, a person can develop hemophilia later in life. The majority of cases involve middle-aged or elderly people, or young women who have recently given birth or are in the later stages of pregnancy. This condition often resolves with appropriate treatment.
