Many unicellular organisms are unable to move by themselves. Instead, they are transported by air, water or other organisms. Although there are some unicellular organisms that have adapted to move independently. For example, bacteria can have one or multiple flagella, which allows them to move. Multicellular organisms require movement to function and survive.
The bone is a living tissue made up of cells with similar structures that work together to perform a shared function. There are 206 bones in the adult human skeleton, which provide structure and support to the body, protect vital organs, and enable movement. When a bone is broken, it has the ability to repair itself.
Below, you can see some of the major bones in the body.
There are four primary functions of the skeleton:
The skeleton supports the body and without this support, we would not be able to maintain an upright posture.
The skeleton protects our major organs.
There are different kinds of blood cells:
Bone marrow is a soft, spongy tissue that produces red and white blood cells. Healthy bone marrow is important in the body and is located at the centre of certain large bones.
Bones play an important role in body movement, allowing the body to move as a whole or its individual parts. This is because they transmit the force from muscle contractions.
