Copyright 2009 Pearson Education, Inc., publishing as Benjamin Cummings Bones of the Pelvic Girdle The total weight of the upper body rests on the pelvis It protects several organs Reproductive organs Urinary bladder Part of the large intestine 17.

Copyright 2009 Pearson Education, Inc., publishing as Benjamin Cummings Gender Differences of the Pelvis The female inlet is larger and more circular The female pelvis as a whole is shallower, and the bones are lighter and thinner The female ilia flare more laterally The female sacrum is shorter and less curved The female ischial spines are shorter and farther apart; thus the outlet is larger The female pubic arch is more rounded because the angle of the pubic arch is greater 20.
