What Are the Bones’ Five Functions?

The foundation of your skeletal system are your bones. They’re lightweight structures that are incredibly strong. Around 206 bones make up the body of an average adult.

Your bones perform five essential bodily activities, including the following:

  • Assisting you in moving by supporting your body. Your bones literally support and prevent the collapse of your body. Your posture depends on your bones. Moving also requires the ability to move your weight around your bones and coordinate your bones.
    keeping your internal organs secure. Your bones protect your inside organs against blows, piercings, and other types of harm. Your ribs, for instance, guard your heart and lungs, while your skull shields your brain.
    Producing your blood cells.
  • Your platelets, red blood cells, and white blood cells are made in particular types of bones.
    Your bones are where these cells are created. Red blood cells carry oxygen to your organs, white blood cells help fight infections, and platelets aid in blood clotting.
  • Storing and releasing fat. Certain types of bones store fat and then release it when your body needs energy.
  • Storing and releasing minerals. Bones can also store necessary minerals when their levels are too high in your blood. Then, your bones will release the minerals when your body needs them. Examples of these minerals include calcium, phosphorus, and vitamin D.
    What Is Your Skeletal System?

Your bones join together to make your skeleton: the structure that your entire body is built around — part of your musculoskeletal system.

Your skeletal system functions as a structural lattice that the rest of your body is built around and depends on for support.

Besides bones, other parts of your skeletal system include:

Ligaments. These are strong tissues that connect your bones to one another.
Cartilage. This is a semi-rigid tissue that covers bones where they touch one another. It provides a flexible and smooth surface for movement.
Tendons. These connect your bones to your muscles.

What Are Bones Made Of?

Bones are made from three different kinds of cells and have three different layers. Their general structure is a combination of a protein called collagen and a molecule called calcium phosphate. These weave together to form their strong, lightweight structure.

The three cell types that form bones are:

  • Osteoblasts. These make new bone tissue and help repair damage to your bones.
  • Osteocytes. These are mature bone cells that help the bones of newborns mature.
  • Osteoclasts. These break down your bones and help form them into their correct shapes.

The three layers of a bone are:

  • Periosteum. This is a tough outer coating to your bones that helps protect them.
  • Compact bone. This is just under the periosteum. It’s hard, white, and smooth. It’s also the main part of the bone that lends firmness and support to your skeletal system.
  • Spongy bone. This is the soft, inner layer of your bones. It’s full of holes where bone marrow can fit. There are two types of marrow — one kind that makes blood cells and one kind that stores fat and minerals.
    What Are Different Types of Bones?

The three main types of bones are:

  • Bones that make blood cells. These are bones that contain red bone marrow. Examples of bones that have red bone marrow include your pelvis, sternum, humerus, and femur.
  • Bones that store fat. These are bones that contain yellow bone marrow. Yellow bone marrow stores fat in the form of adipose tissue. It can release energy when your body needs it in the form of triglycerides — a type of fat found in your blood.
  • Bones that form joints. Some bones come together with other bones, ligaments, and cartilage in structures called joints. There are different types of joints that are defined by exactly how your bones come together in that region. These help your body move in different ways.

When you’re born, your bones mostly contain red bone marrow, but it becomes yellow in your arms and legs as you grow up. This reflects your body’s changing needs for blood cell production versus fat storage.

There are many different conditions that can impact your skeletal system, and your bones in particular. Examples of these are:

  • Arthritis. A painful condition where your joints wear down. There can also be inflammation in your joints.
  • Scoliosis. This is when the bones in your spine are no longer straight.
  • Cancers. There are certain cancers that can form inside of your bones and impact your skeletal system.
  • Breaks. Bones can break — sometimes very badly. Sometimes, your bones can heal small breaks on their own, but oftentimes, you’ll need medical help to fix a broken bone.
