Having learnt what the Cardiovascular and Respiratory system is required to do and where both the blood and the air is transported around the body, we are ensured to understand that both systems are linked together by aiming to achieve the same goal; transporting oxygen to the cells around the body and the diffusion of carbon dioxide also. Remembering that the Respiratory System has a function of supplying the body with oxygen from inhalation which is to be passed around to all the working cells, and the exhalation of Carbon Dioxide also. In addition, having the Cardiovascular System being the main system of transporting the oxygen from what the Respiratory System have supplied us with, the blood and blood vessels enable it to travel to a variety of cells within the human body. For short, the Cardiovascular System and the Respiratory System linked, is known to be the 'Cardio-Respiratory System' - this means it consists of the heart, lungs, blood vessels and blood. The Cardio-Respiratory System has a function of providing the oxygen we have breathed in through inhalation to be transported around the body through the variety of networks known to be the arteries, capillaries and veins. In addition to the removal of the waste products that are within the body to be transported via the veins which deal with deoxygenated blood to be transported back to the lungs, where when we exhale and breathe out.
When our diaphragm contracts resulting in us inhaling air from the environment that contains oxygen, it then travels down the path into the lungs where gas exchange takes place within the alveoli. The blood vessels are the main transporter to get the oxygen to the lungs via the arteries and capillaries which deal with the oxygenated blood. Having the oxygen that we have inhaled (linked to the respiratory system) the oxygen is now diffused from the network of the capillaries (linked to the Cardiovascular System) into the alveoli which are thin walled sacs that fill with gases, for gas exchange. The waste products, like carbon dioxide will then diffuse through the wall of the alveoli into the bloodstream where the capillaries carry the waste to the veins which deal with deoxygenated blood. This network then passes through the heart where the deoxygenated blood will travel through the pulmonary artery in order to transport to the lungs where when the brain informs the lungs that carbon dioxide needs to be released, the diaphragm will relax (gets biggers, as the lungs are pushing out the carbon dioxide so they get smaller, the diapragm is in need of filling the space) resulting in the waste products being diffused through the mouth and nasal cavity. When we inhale, the diaphragm contracts - (flattens so that when our lungs fill up with oxygen we have less area for the diapragm) this is when the blood will then become oxygenated (meaning the blood has oxygen) resulting in this travelling to the left side of the heart through the arteries and capillaries. Remembering that after the blood has passed the alveoli ready for gas exchange, the deoxygenated blood then returns to the lungs, with wastes, in order to be exhaled from the lungs out of the body. After this, when we breath the blood become oxygen-rich blood where it will travel to the cells in order to keep out bodies functioning which also means the cycle starts again.
When we exercise, you should understand that the heart beats faster - why? this means that the body is working harder in order to ensure that the cells are receiving the oxygen that it needs quickly. Also throughout physical activity, the breathing rate becomes much quicker along with the heart beating faster too, this is because the blood is wanting more oxygen to be inhaled so that the blood can transport it around the body to the working cells, through the 3 main networks known to be the arteries, capillaries and veins. If your heart beats fast, it is pumping the blood quickly around the body along with wanting oxygen received through respiration - breathing.
You will also find that if your body is not enduring in physical activity and the heart beats faster due to being scared, your breathes remain the same. This is because the sensors within the brain have detected that the emotion of feeling scared is within the body, and this is the panicking experience that is resulted. When you are scared, this does not mean that you are tired as the normal breathing rate will remain the same, just the heart is pumping faster because the brain has detected you are worried. In comparison, to exercising the body is in demand of faster breaths to get the muscles working for longer.
Remember that the Cardio-Respiratory System has a formula: Heart + Lungs = Cardio-Respiratory System - this system is the heart pumping the blood that has oxygen from breathing in, around the body through blood vessels and the removal of waste products from us breathing out too.
