Hematology

Hematology is a branch of medicine concerning the study of blood, the blood-forming organs, and blood diseases.

Also its The study of the nature, function, and diseases of the blood and of blood-forming organs.

Blood is basic to almost all the body’s functions, and a blood test can reveal more about your physical condition than almost any other kind of examination, so hematology is an important medical specialty, with many separate subjects. Since blood cells are formed in the bone marrow, the bones are one important focus for hematologists. The coagulation, or thickening, of the blood is another important subject, since coagulation is what keeps us from bleeding to death from even small wounds. And there are dozens of serious blood diseases, including anemia (a lack of red blood cells) and leukemia (cancer involving a buildup of white blood cells).
