Functions Of The Skeletal System- Importance and Benefits

The skeletal system is one of the most important systems in the body. Its main function is to protect our bodies by giving it structure and shape. Explore this article to learn more about how the skeletal system works and what you can do to help keep your bones healthy. 

What is the Skeletal System?

The skeletal system is the framework of the human body. It is made up of bones, which provide support and protection for the body, and joints, which allow the bones to move. The skeletal system also includes the muscles, which are attached to the bones and help them to move.

Why Is the Skeletal System Important?

The skeletal system is one of the most important systems in the human body. It provides support and structure for the body, and protects vital organs. The skeletal system is also important for movement. The bones act as levers, which allow the muscles to move the body.

The Functions of the Skeletal System

The bones provide a rigid structure that helps to keep the human body upright, and also protects vital organs from injury. The rib cage protects the heart and lungs, while the skull protects the brain.

Another important function of the skeletal system is to provide a place for the muscles to attach. Muscles need something to pull against in order to create movement. The bones of the skeleton provide this resistance.

The skeletal system also plays a role in blood cell production. Bone marrow is responsible for producing red blood cells, white blood cells, and platelets.

Without the skeletal system, the human body would not be able to function properly. It is essential for supporting, protecting, and moving the human body.

Tips to Help You Care for Your Skeletal System

The skeletal system is the framework of the human body and it plays a vital role in our overall health. Here are some tips to help you keep your skeletal system healthy:

1. Get enough calcium and vitamin D: Calcium is essential for strong bones and teeth, while vitamin D helps the body absorb calcium. Good sources of calcium include dairy products, leafy green vegetables, and certain types of fish. You can get vitamin D from exposure to sunlight or by taking supplements.

2. Exercise regularly: Weight-bearing exercises such as walking, running, and lifting weights help keep your bones strong. Regular exercise also helps reduce the risk of osteoporosis, a condition that leads to weak and fragile bones.

3. Don’t smoke: Smoking decreases the amount of blood flow to the bones and increases the risk of bone loss. It also increases the risk of developing osteoporosis.

4. Eat a healthy diet: A diet rich in fruits, vegetables, and whole grains helps keep your bones healthy and reduces your risk of developing osteoporosis. Avoiding processed foods and sugary drinks is also important for bone health.

What Are The Different Types of Bones?

There are different types of bones in the skeletal system and each one has a specific function. The four main types of bones are:

Cortical bones: These are the hardest and densest bones in the body and they make up the majority of the skeleton. They protect vital organs and provide support for the body.

Trabecular bones: These are less dense than cortical bones and have a spongy, honeycomb-like structure. They are found in areas where stress is not as great, such as the vertebrae in the spine.

Flat bones: As their name suggests, flat bones are thin and flattened. They provide protection for delicate organs, such as the brain, and support large muscles, such as the chest muscles.

Irregular bones: These have a variety of shapes and are found in areas where stress is heavy, such as the hip bone.

What Are Bones Made Of?

Bones are made of living tissue, which means they’re constantly growing and changing. The skeletal system is made up of three main cell types: osteocytes, osteoblasts, and osteoclasts. 

  • Osteocytes are the most abundant type of cell in bone and they maintain the bone matrix. 
  • Osteoblasts are responsible for the formation of new bone tissue. 
  • Osteoclasts break down old bone tissue. and they’re held together by a network of proteins. This gives bones their strength, while also allowing them to bend and flex as needed.


Bones store minerals like calcium, which help keep our bodies healthy and functioning properly. Without the skeletal system, our bodies would be weak and frail. So, the next time you fall without getting hurt much, be thankful to your bones!
