Cardio-vascular & Respiratory system working together to carry out their functions in realtion to the metabolsim and the use of energy in the body

The respiratory and cardiovascular systems work in different ways with different functions in realtion to the metabolism and with the use of energy. The cardiovascular system in the human body is made up of the heart and blood vessels, which are divided into arteries, veins and capillaries. The heart is responsible for pumping the blood throughout the blood vessels and is divided into four chambers, two of which are responsible for moving deoxygenated blood and two of which move oxygenated blood. Oxygenated blood, which is pumped through the body via the arteries, supplies the body's tissues with oxygen that they need to live without this the red blood cells and other living cells would die. Blood in the arteries is under high pressure this is because the blood needs to quickly get to the living organs before the living cells dies, oxygenated blood first needs to go to the capillaries, which are very small and low-pressure blood vessels that are responsible for supplying the oxygenated blood to the tissues. Once the capillaries have delivered their oxygen, they also absorb excess carbon dioxide into the blood and then deliver it to the veins, which then supply the blood back to the heart.The respiratory system is a apart of inhaling oxygen and exhaling carbon-dioxide, the structures (such as muscles) that help move air in and out of the lungs. The airway, which begins with the nose and mouth, continues down through the throat into the bronchi, which are small airways that eventually feed into the lungs, which are lined with cells called alveoli. The other part of the respiratory system is the muscles, such as the muscles between the ribs and other parts of the chest area, this cause's the lungs to expand and contract. When the size of the lungs changes, so does the pressure inside, leading to air either coming in (inhalation)of oxygen or being forced out (exhalation)of carbon-dioxide.

The cardiovascular and the respiratory system both work to get the
