Textbook Question

Name the major functions of the skeletal system.

Verified step by step guidance

The skeletal system provides structural support for the body, serving as a framework that maintains the shape and posture of the organism.

It protects vital organs, such as the brain (protected by the skull), heart and lungs (protected by the rib cage), and spinal cord (protected by the vertebrae).

The skeletal system facilitates movement by serving as attachment points for muscles. When muscles contract, they pull on bones to produce movement.

It plays a critical role in mineral storage, particularly calcium and phosphorus, which are essential for various physiological processes.

The skeletal system is involved in hematopoiesis, the production of blood cells, which occurs in the red bone marrow found within certain bones.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Support

The skeletal system provides structural support for the body, serving as a framework that maintains the shape and posture of an organism. It supports soft tissues and organs, allowing for the proper functioning of various bodily systems.

Movement

Bones act as levers that facilitate movement when muscles contract. The joints between bones allow for a range of motion, enabling activities such as walking, running, and lifting, which are essential for daily functioning and mobility.

Protection

The skeletal system protects vital organs from injury. For example, the skull encases the brain, while the rib cage shields the heart and lungs, providing a critical defense against physical trauma and contributing to overall health.
