Humans have over 200 bones in their bodies, all of which come together to form part of the skeletal system. The skeletal system has a number of different functions which can help to explain the need for bones in the human body. The five basic jobs of bones are as follows: For protection, shape, movement, support and blood production.

To understand how bones provide us with protection, we can look at the examples of the cranium and rib cage, which protect the brain and lungs respectively. Bones are dense and strong, which means they act as barriers in front of soft tissues like the brain and heart to protect them from impact that could otherwise cause severe damage.

Bones also provide us humans with shape. The length and width of the individual bones in our skeletal system determines how tall or short we are, and can also define certain body types - for example, whether or not we have broad/narrow shoulders or wide/narrow hips.

In terms of movement, muscles attach to bones to enable us to move our limbs in different directions. Muscles contract to allow bones to move in many different ways, including when throwing a ball or simply walking in a straight line.

The bones in the human body are also essential for support and structure. Our vertebral columns keep us upright, whilst all of our organs are kept in place during basic movement and more vigorous exercise with the help of the body's various bones.

The fifth and final main function of the skeletal system is for blood production. Red and white blood cells are produced in the marrow of certain bones in our bodies and help transport oxygen around the body and fight against infections such as coughs and colds respectively.

It gives proper shape to our body.
It is site for the production of RBCs and WBCs.
We are able to stand, do different activities because of it.
It protects our variou delicious organs like heart, lungs , kidney etc.

Shape for our body
Support he body in the correct position or posture
Support the internal organs
Protect the delicate vital organs of the body
Provide sites for muscle attachment
To work as a level system
To enable us to make large and fine movements
To produce red and white blood cells

The body structure and shape is the result of the arrangement of the muscles and bones. Muscles are flexible body structures while bones are hard in nature, therefore, bones provide a shape and support to the body. Bones also provide protection to the delicate parts of the body because skull and skeleton is made up of bony structure. Bones also increase the size of the body because with the increase in the body cells, bones also grow in size. Moreover, bones play an important role in moving the body for example, when bones are broken then body movement is not possible.

There are two main jobs that the skeleton does— it supports the body, and it protects delicate organs.
The skeleton is the frame that holds man erect. It is made mostly of bones - A baby is born with as many as 270s mall, rather soft bones in his framework. A fully grown person usually has 206, because some bones become fused, or grow together.
Bones fit together at joints and are held fast by ligaments, which are like tough cords or straps. Some joints can be moved freely. For example, when you run, you move your legs at the hip and knee joints. When you throw a ball, you move your arm at the shoulder and elbow joints.
Some joints cannot be moved at all. At the base of the spine the bones are fused, forming one bony plate that fits into another. Neither moves. The joints in your skull are solid, too, except for those in the jaw.
The protection that the skeleton provides includes the hard, bony cap of the skull. This protects the brain. The rib cage protects the heart and lungs. And the backbone, or hollow spinal column, protects the spinal cord, the body's trunk line of nerve cables. The backbone is actually a string of small bones.
It is hard for us to think of bone as living tissue, but it is. It grows when a person is young. For example, the thigh bone may triple in length between the time a person is born and the time he is fully grown.
Bones grow in length and thickness as calcium and other minerals are added to them. And since bone is living tissue, it must be fed. The outside of the bone is covered with a thin, tough skin. The skin holds many tiny blood vessels that carry food to the bone cells.

Firstly our bones protect such things as hearts... Plus our bones make around 1 billion cells per day! Plus if we did not have bones we would fall down like jelly!

We need bones to do every day things like walk and pour some juice. Without bones we would be just skin and blood we wouldn't be able to stand or do anything like talk and walk.  WE WOULD BE DEAD

Well mainly to keep the body standing it like a wall house you need steels in order for it to stand.

Protection, support, shape, movement, blood production.
Try remembering it in a rhyme e.g. Paul Scholes Score Many Back-heels. That cues the first letter of the functions of the skeleton.

The skull is protective to the brain. The brain moves your body around the world the heart brings life to your body. If it stops pumping you can die as we all know the lungs help us breathe. The rib cage protects the heart & lungs the spine supports the back

You need calcium in your body to have healthy and strong bones.  We have a vertebrate which keeps all bones together and is the center structure of all bones. We have long bones,short bones, and irregular bones. I can't remember other stuff but I do know that with out bones we be like pudding on the floor without them;-)

Because it gives us the power to stand up and move around without it, we would be a jelly and would not have the power to stand up.

The major difference between vertebrates and invertebrates is, the former has a backbone, which the latter is not blessed with. This is a factor of definite superiority as a backbone and all other bones of the body are given to shape up the body and provide it with a balanced degree of support. Another important function of bones is to provide protection for the delicate yet important organs of the human body. The third function that increases the importance of bones in the functioning of a human body is they become the major source of succor while a person moves. The total number of bones in the body are 206 for an adult while a baby could have as many as 270 bones. The reason behind this difference is that bones grow together and fuse as the person grows older. Bones also contain a yellowish-red fatty substance called bone marrow, which is the blood making factory of the body that also keeps bones lighter without reducing the extent of their strength.

To add to the first answer.  We need bones for a few other reasons.  Our rib cage serves to protect many of our vital organs and bones are essential for the use of muscles.  All muscles have origin and insertion points on bones AND the center of our bones known as marrow produce red blood cells...bones are VERY important!!!

Because bones are your life! (no seriously its true) You need bones because how are you suppost to even press the buttons on the keyboard like dah!! And you would be stuck to the floor, because you will be all flobby, which means your spine is a bone and without a spine your in a wheelchair, Thanx for reading
