How Does the Skeletal System Help Us?

The skeletal system is a complex collection of bones joined together into a form that aids the human body in a number of ways that help us. In addition to providing general structure, bones have a number of additional functions essential to day-to-day life.

Size

The human skeleton is composed of 206 bones that create the basic framework of the human body. These bones, divided into the main axial section of the torso and head and the extremities, provide rigid stability to the form.

Function

Organs that make the human body function are protected by the skeletal system. The sternum and rib cage protect the vital organs of the heart and lungs, while the skull encases the brain.

Features

The skeleton is essential to helping the body carry out movement. Connections known as tendons link bones and muscles together to help joints bend. The muscles contract, pulling the bones, thus creating bodily movement.

Significance

Within the marrow in bones, the production of blood cells occurs. According to Minnesota State University, the liver destroys millions of red blood cells. In response, the bones create an estimated 2.6 million red blood cells every second.

Considerations

Buildups of calcium and phosphorus occur within the blood. When too much of these minerals are present, the bones absorb the excess. After the blood depletes its supply, the skeletal system responds by replenishing the blood.
