Female anatomy. Computer artwork of a female body showing the skeletal, urinary, nervous, reproductive, respiratory and digestive systems. The nervous system (green) comprises the brain (top), spinal cord (not seen) and the nerves of the periphery nervous system (PNS). The bones of the skeleton provide a structural framework and protect the internal organs. Some of the organs visible here include the lungs (pink, top left and right), the heart (red, upper centre), the liver (brown, just below the heart), the kidneys (red, either side of the liver) and the uterus (pink, lower centre). Also seen are the mammary glands (orange, top left and right) and the intestines (centre).
