Why do we have bones?

Answer 1

Bones are a piece of framework that supports skin and varioun human organs. Apart from that it also protects delicate parts of human gody.

Thats it.

Answer 2

Because of the Earth's gravitational force, organisms made up of more than just a few cells wouldn't be able to move about without some sort of support. Nature has a way of trying out various ways of solving problems like this. That's why there is so much diversity on our planet. So, two ways that nature successfully gave support to evolving organisms were with an exoskeleton and an endoskeleton. An exoskeleton is basically a suit of armor, protecting all of the soft, vulnerable insides and giving structural support for movement. Insects, lobsters, and clams all have exoskeletons. An endoskeleton is what humans and many other animals have. It's an internal support structure. Although an endoskeleton doesn't provide protection for all of our soft, vulnerable parts (except the rib cage), there are advantages to this type of support style. An endoskeleton provides shape and structure (like the frame of a house), a wider range of motion, and better support against gravitational forces. The largest animals on the planet have endoskeletons, not exoskeletons.

So, if we didn't have bones (an endoskeleton) we wouldn't be able to walk around, drive a car, play video games, or anything else we normally do in life. In fact, without the existance of endoskeletons, humans wouldn't have evolved the way we did at all.

Answer 3

Some animals have a skeleton on the outside. These are insects, crustaceans (lobsters) and such. Others - generally vertebrates - have an ENDOskeleton. In both cases, these structures are connecting points for muscle tissue. Because the muscles are connected to bones at either end - when they contract - a movement takes place (an arm bends, a leg extends). An additional benefit of the bone structure is that it helps compensate for the pull of gravity. Thus, animals with bones or exoskeletons can move on 2 or 4 legs (or like snakes with no legs) without having ooze from position to position like an amoeba - or live in a weightless enviromnent like a jellyfish in water.

Answer 4

The human body is an elastic skin bag of chemicals. Bones serve the function of a coat hanger for the body. The body has structure. The hard surface provides protection for brain-cranium and a cage for the vital organs of the body-ribs and the spine-vertebrae, and the bones of the pelvis. The marrow in our bones is the site for blood cell production which provide for oxygenation of the blood plus protection from infection and provide a clotting factor for the blood.

Answer 5

Bones are not only the framework that allows our body to stand upright and move about with the use of our muscles. But bones like our rib cage protect vital internal organs like the heart and lungs.

Answer 6

We have bones in order to give ourselves a structure and support, and for protection of our soft organs. Bones are also necessary in order for us to walk, run, and move in general. If we didn't have bones we would be a puddle of skin, blood, and organs laying on the floor...ick.

Answer 7

We need bones to give us shape and support the body, and protect the vital organs. If you want to move, you need bones if you are a large organism!

Answer 8

The bones support everything in our bodies. It holds up our muscles, skin, and fat and the skin protects the organs and blood, etc.

Answer 9

Bones are very important. with out bones we can't do anything , even to sit , stand , walk or anything.

Answer 10

bones gives shape to oure body!!
