Answer:The pelvis is a bony structure located at the base of the spine, and it consists of several bones that are divided into two main parts: the greater pelvis (or false pelvis) and the lesser pelvis (or true pelvis).
Step-by-step explanation:
1. Greater Pelvis (False Pelvis):
Location: The greater pelvis is the expanded, upper part of the pelvic cavity.
Protected/Supported by: The greater pelvis is not directly involved in supporting or protecting any organs. It forms the upper part of the pelvic basin and does not house any vital organs.
2. Lesser Pelvis (True Pelvis):
Location: The lesser pelvis is the narrower, lower part of the pelvic cavity. It is deeper and more enclosed than the greater pelvis.
Protected/Supported by:
Protected: The lesser pelvis protects several important organs, including parts of the digestive, reproductive, and urinary systems. For example, in females, the uterus and part of the digestive system are located within the lesser pelvis.
Supported: The lesser pelvis provides support for the weight of the upper body and houses and protects the pelvic organs, such as the bladder and reproductive organs, in both males and females.
