Bladder, lower colon, lymph nodes, uterus, and vagina
I'm guessing you mean "pelvis"... There is no such thing as a pelvic; that is an adjective.
Your pelvis is basically your hipbone. It is actually more than one bone, consisting of the os coxa, the sacrum, and the coccyx. You can tell if a skeleton is male or female by the size of the gap in the pelvis. For females it is larger to make it easier for childbirth.
That was a bit of information on the pelvis. Now, to the question. The pelvis isn't really a protecting bone, but it may help protect the lower parts of the digestive system and reproductive organs.

Symptoms of pelvic organ prolapse include stress incontinence (inadvertent leakage of urine with physical activity), a vaginal bulge, painful sexual intercourse, back pain, and difficult urination or bowel movements.
A full bladder, pregnant uterus, or full descending colon are pelvic organs that can be palpated through the skin.
The uterus or womb, is a hollow muscular organ of the female reproductive system. It is located between the bladder and the rectum, in the pelvic area.
