Definition

1. Noun:
   • A basin-shaped structure in the skeleton of many vertebrates: The pelvis is the large bony structure at the base of the spine to which the legs (or hind limbs) are attached. It is composed of the hip bones, sacrum, and coccyx.
   • A funnel-shaped cavity or structure in the body: In anatomy, the pelvis can also refer to the basin-like cavity formed by the hip bones, containing and protecting organs such as the bladder and reproductive organs. In renal anatomy, it specifically refers to the funnel-shaped part of the kidney where urine collects before entering the ureter.
