Human body anatomy. Artwork showing the anatomy of a standing human body. Bones of the skeleton, muscles of the limbs, and major organs are seen. At top is the brain (white) in the skull & spinal cord passing into the neck. The thorax contains the heart with arteries (red) and veins (blue); around the heart are the lungs with bronchiole air tubes. Beneath the lungs are lobes of the liver in the abdomen. The pancreas (yellow), gall bladder (green) and two kidneys (pink) with ureters are seen. The small intestine is coiled, occupying the lower abdomen. Muscle blocks (red) in the limbs enable movement, & these are attached to bones of the limbs, pelvis and shoulder, by white tendons.
