Which structure is responsible for supporting the organs in the lower abdominal cavity?

1. Sternum

2. Pelvis

3. Vertebrae

4. Collarbone

The correct answer is: Pelvis

The pelvis is the correct answer because it serves as the foundational structure that supports the organs located in the lower abdominal cavity. It is a bony structure that forms the base of the spine and connects to the femors, allowing for both the support of internal organs and the connection of the lower limbs to the axial skeleton. The pelvis encases and protects important organs such as the bladder, reproductive organs, and parts of the intestines. Additionally, it provides stability to the body when in an upright position and during movement. This anatomical feature plays a crucial role in maintaining the integrity and function of the structures within the abdominal cavity. In contrast, the sternum primarily protects the heart and lungs, the vertebrae safeguard the spinal cord and provide axial support, while the collarbone (or clavicle) connects the arm to the body but does not directly contribute to supporting the organs in the lower abdomen.
