Respiration and the Respiratory System-
The respiratory system is in charge of getting the oxygen needed for respiration to the blood flow where it is passed by the blood cells around the body to reach each living cell.
The lungs have a huge blood supply and a huge surface area so they are very effective at getting oxygen out of the air. They are also in charge of getting rid of the carbon dioxide excess and some of the excess water as water vapour. It is the lungs job to get the oxygen and the heart has to pump it around the rest of the body. Energy metabolism; when people are exercising their muscles are contracting and they are using more energy so they will need more oxygen getting to the muscles and my heart will beat fast which will send the oxygen faster to my muscles.
It is the role of the respiration system to ensure enough oxygen is brought into the body to feed metabolism and generate energy for the muscles. This is why when we are using more energy, our breathing rate increases bringing that additional oxygen into the lungs.
Respiration and the circulatory system-
The circulatory system is a network of blood vessels which take blood to each living cell in the body.
It is made up of the heart and arteries which their role is to take blood to the body from the heart and capillaries which allow the blood to get to the separate cells and veins which take the blood back to the heart to be sent around again. When you breathe in it is the hearts job to send the oxygen around the body to every cell once the lungs have got the oxygen in them. Energy metabolism; when you do exercise your heart pumps the blood faster around your body which contracts the muscles and pumps more oxygen around your body.
The respiratory system takes away the oxygen needed for the body from the outside of the body and brings it into the lungs where it is pushed around the lungs into the blood stream. The circulatory system brings and carries the
