Final answer:
A wide and shallow pelvis with a short sacrum is a characteristic of the female pelvis. This pelvis structure increases the risks of difficult labor and delivery, as well as pelvic floor dysfunction.
Step-by-step explanation:
A wide and shallow pelvis with a short sacrum is a characteristic of the female pelvis. The female pelvis is wider than the male pelvis to accommodate childbirth, has a larger subpubic angle, and a broader and more shallow lesser pelvic cavity. These characteristics increase the risks of difficult labor and delivery and pelvic floor dysfunction.
