The Skeletal System
The pelvic (hip) girdle transfers the weight of the upper body to the legs. It consists of a pair of coxal bones (os coxae, hip bones), each of which contains three fused bones: the ilium, ishium, and pubis. Together with the sacrum and coccyx, the pelvic girdle forms a bowl-shaped region, the pelvis, that protects internal reproductive organs, the urinary bladder, and the lower part of the digestive tract. Features of these bones are given in Figure
