Verified step by step guidance

Understand the anatomy of the pectoral girdle: The pectoral girdle consists of the clavicles (collarbones) and scapulae (shoulder blades). It is part of the appendicular skeleton and connects the upper limbs to the axial skeleton.

Review the primary function of the pectoral girdle: Its main role is to provide attachment points for muscles and facilitate the movement of the upper limbs. It also serves as a structural connection between the upper limbs and the axial skeleton.

Eliminate incorrect options: 'Produce red blood cells' is primarily a function of bone marrow, not the pectoral girdle. 'Support the pelvic organs' is a function of the pelvic girdle, not the pectoral girdle. 'Protect the heart and lungs' is primarily the role of the rib cage and sternum.

Focus on the correct answer: The pectoral girdle's primary function is to attach the upper limbs to the axial skeleton, enabling movement and providing structural support.

Summarize the concept: The pectoral girdle is essential for upper limb mobility and serves as a connection point between the appendicular and axial skeletons, facilitating a wide range of movements.
