Pediatrics (the term comes from the Greek words paidos - child, and iatreia - to treat) is a branch of medicine that studies the anatomical and physiological characteristics of a child's body during growth and development. The tasks of pediatrics include the study of the mechanisms and causes of the development of various childhood diseases and the development of effective methods of their treatment. To detect childhood diseases at an early stage and effectively combat them in modern pediatrics, high-precision diagnostic methods are used.
