How does the skeleton contribute to protection?

Protection – the bones of the skeleton protect the internal organs and reduce the risk of injury on impact. For example, the cranium protects the brain, the ribs offer protection to the heart and lungs, the vertebrae protect the spinal cord and the pelvis offers protection to the sensitive reproductive organs.

How does the skeleton support and protect?

Bones provide a rigid framework, known as the skeleton, that support and protect the soft organs of the body. The skeleton supports the body against the pull of gravity. The large bones of the lower limbs support the trunk when standing. The skeleton also protects the soft body parts.

How does the skeleton provide protection against infection?

The vertebral column holds the body upright. Movement – muscles are attached to bones, which are jointed. When the muscles contract the bones move. Blood production – red blood cells (to carry oxygen) and white blood cells (to protect against infection) are produced in the bone marrow of some bones.

How do bones function in protection?

Bones are made up of a framework of a protein called collagen, with a mineral called calcium phosphate that makes the framework hard and strong.

What are the 6 functions of the skeleton?

It is composed of 270 bones at birth and decreases to 206 bones by adulthood after some bones have fused together. The human skeleton serves six major functions: support, movement, protection, production of blood cells, storage of ions, and endocrine regulation.
