Multiple Choice

Which statement best describes the skeletal system?

It provides structural support and protection for the body, and serves as a site for blood cell formation.

It breaks down food into nutrients for absorption.

It regulates hormone production and maintains homeostasis.

It is responsible for transporting oxygen and nutrients throughout the body.

Verified step by step guidance

Step 1: Begin by identifying the primary function of the skeletal system. The skeletal system is responsible for providing structural support to the body, protecting vital organs (e.g., the skull protects the brain, and the rib cage protects the heart and lungs), and serving as a site for blood cell formation within the bone marrow.

Step 2: Eliminate the incorrect options by matching their descriptions to other systems. For example, 'It breaks down food into nutrients for absorption' refers to the digestive system, not the skeletal system.

Step 3: Similarly, 'It regulates hormone production and maintains homeostasis' is a function of the endocrine system, not the skeletal system.

Step 4: The statement 'It is responsible for transporting oxygen and nutrients throughout the body' describes the circulatory system, which includes the heart, blood vessels, and blood.

Step 5: Conclude that the correct description of the skeletal system is: 'It provides structural support and protection for the body, and serves as a site for blood cell formation.' This aligns with the known functions of the skeletal system in Anatomy & Physiology.
