The pelvis is the lower part of the torso. This area provides support for the intestines and also contains the bladder and reproductive organs. There are some structural differences between the female and the male pelvis. Most of these differences involve providing enough space for a baby to develop and pass through the birth canal of the female pelvis. As a result, the female pelvis is generally broader and wider than the male pelvis. There are two hip bones, one on the left side of the body and the other on the right.
The pelvic girdle is a ring-like bony structure, located in the lower part of the trunk. It connects the axial skeleton to the lower limbs. In this article, we shall look at the anatomy of the pelvic girdle — its bony landmarks, functions, and its clinical relevance. Ligaments attach the lateral border of the sacrum to various bony landmarks on the bony pelvis to aid stability.
What is the pelvis?
The pelvis is the lower portion of the trunk, located between the abdomen and the lower limbs. The floor of the pelvis is made up of the muscles of the pelvis, which support its contents and maintain urinary and faecal continence. There are many organs that sit in the pelvis, including much of the urinary system, and lots of the male or female reproductive systems. The skin, tissues and organs in the pelvis are supplied by the vasculature of the pelvis, and innervated by many nerves of the pelvis, including the pudendal nerve.

Pelvis , also called bony pelvis or pelvic girdle , in human anatomy , basin-shaped complex of bones that connects the trunk and the legs, supports and balances the trunk, and contains and supports the intestines , the urinary bladder , and the internal sex organs. The pelvis consists of paired hipbones, connected in front at the pubic symphysis and behind by the sacrum ; each is made up of three bones—the blade-shaped ilium , above and to either side, which accounts for the width of the hips ; the ischium , behind and below, on which the weight falls in sitting; and the pubis , in front. All three unite in early adulthood at a triangular suture in the acetabulum , the cup-shaped socket that forms the hip joint with the head of the femur thighbone. The ring made by the pelvis functions as the birth canal in females. The pelvis provides attachment for muscles that balance and support the trunk and move the legs, the hips, and the trunk. In the human infant the pelvis is narrow and nonsupportive. As the child begins walking, the pelvis broadens and tilts, the sacrum descends deeper into its articulation with the ilia, and the lumbar curve of the lower back develops. In the semierect apes , the centre of gravity falls near the shoulder , and the abdominal organs depend from the vertebral column. The ilium is elongated and somewhat spoon-shaped, and the pelvis is oriented horizontally.
