The ribs expand so that we can breathe. When the ribs expand, the volume of the pleural space increases and the lower pressure brings in air.
Skeletons do not move on their own. Movement is achieved through the muscles that are attached to the skeleton and controlled by signals from the nervous system, which coordinate and stimulate muscle contractions. Bones provide the structure and support for movement, but they do not have the ability to move on their own.
Muscles and ligaments play a crucial role in supporting and moving the skeleton. Muscles provide the force needed to move the bones, while ligaments connect bones to each other, providing stability and preventing excessive movement. Together, they work to support the skeleton and allow for coordinated movement.
The skeletal system has many important functions, including: 1. Providing a sturdy attachment site for your muscles, so that your body can move, and so that the body does not exist in a "gelatinous" state. 2. The skeletal system can be divided into two "parts"; the Axial skeleton and the Appendicular skeleton. The axial skeleton basicallly consists of the bones of your skull and trunk (spine, ribs,). The appendicular skeleton is made up of the bones of your arms and legs. The axial skeleton gives your body it's posture, so that it doesn't fall over. It also protects vital organs- the ribs enclose/protect the lungs, and the sterum covers/protects the heart. The liver is also partially protected by your ribs. The bones of your skull protect your brain, etc. The bones of the appendicular skeleton (working w/our muscles) allow us to walk, stand, grasp,and move objects. 3. Many bones store important minerals like calcium and phosphorus, etc. 4. Some bones produce and store bone marrow (red and yellow bone marrow). Red bone marrow produces blood cells.
Muscles are responsible for giving the body the ability to move. These muscles are supported by bones and joints which provide structural support and allow for smooth movement. Additionally, the nervous system plays a crucial role in coordinating muscle contractions and movements.
Bones move by your musclesBones have joints that let them move back and forth, muscles help them move, and you need energy to move your body like healthy How_do_your_bones_move.
The bones form the skeleton and support the body. It is the muscles that move some of the bones to allow us to move our bodies.
A skeleton is a system of bones that force you to move our body
muscle
Animals have joints which allow them to bend around, this is also helped by the fact they have muscles.
Muscles allow the skeleton to move.
Muscles move your bones
The muscle system and the skeleton system are the main body systems that allow the human body to move. When muscles contract and expand it moves the bones, ligaments, and cartilage hence making you move. For more information you can google muscles and skeleton.
The skeleton system serves as a support system for your body, your muscles are attached to your bones by tendons (also known as the musculo-skeletal system)providing the ability to move, and bones protect certain organs. The ribs, for example, are a layer of protection for your lungs and heart. The brain is protected by the surrounding skull. Blood cells are produced in the marrow of bones and bones are used as resevoirs for minerals such as calcium and phosphorus.
The hold you up, and act as levers to allow you to move.
because if we dont have a skeleton we can not move
Skeletons do not move on their own. Movement is achieved through the muscles that are attached to the skeleton and controlled by signals from the nervous system, which coordinate and stimulate muscle contractions. Bones provide the structure and support for movement, but they do not have the ability to move on their own.
The Muscular system helps to move bones.
