Summary
comparison of skeletal and muscular systems
The skeletal system provides the body with support for your soft tissues, protection for your organs and allows movement. The bones are strong, flexible, living and light so that they are of utmost practicality. There are also many different kinds of joints each designed to complete different arrays of movement. Whilst the skeletal system provides support, protection and allows our body to move, it is the muscular system that makes the movement happen. Many of the voluntary muscles in the body work in antagonistic pairs that contract and relax in order to flex or extend parts of our body. The way our skeleton is designed makes this possible.
comparison of respiratory and circulatory systems
The respiratory system's job is to take in oxygen and release CO2. We do this by inhaling air which travels into our lungs via the trachea which brances off into bronchi that branch into bronchiole. It is off these that we find clusters of alveoli. It is here that the circulatory system comes into place. The alveoli sit next to cappilaries, they exchange oxygen and carbon dioxide with the red blood cells; giving the blood oxygen and taking in the carbon dioxide which we then breathe out when we exhale. The blood now high in oxygen travels back in order to be pumped out to supply the body with oxygen and nutrients. All in all the respiratory and circulatory systems are very closely linked as the respiratory system supplies the blood with oxygen so that it can spread it to all of the cells of the body.
