The Tashrih al-badan ( Anatomy of the body ) of Mansur ibn Ilyas ( c. 1390 ) contained comprehensive diagrams of the body's structural, nervous and circulatory systems.

Other medical innovations first introduced by Muslim physicians include the discovery of the immune system, the use of animal testing, and the combination of medicine with other sciences ( including agriculture, botany, chemistry, and pharmacology ), the first drugstores in Baghdad ( 754 ), the distinction between medicine and pharmacy by the 12th century, and the discovery of at least 2, 000 medicinal and chemical substances.
