The cardiovascular system helps blood circulate through a network of vessels in the body to give single cells oxygen and nutrients. The cardiovascular system in our body consists of the heart and blood vessels which are further more split in to capillaries, arteries and veins. The human heart pumps the blood via the blood vessels and is split in to four sections. The right side of the heart moves poorly oxygenated blood and the left side is responsible for moving highly oxygenated blood. Oxygenated blood that is pumped throughout the body by the arteries which is then supplied to the body tissue as they need to survive. The blood in the arteries are under very high pressure this could potentially damage our tissue therefore the oxygenated blood first travels to the capillaries which are quite small, low-pressured vessels which are then responsible to supply blood to the tissue. The capillaries absorb more carbon dioxide into the blood which is then delivered to the veins which is then supplied back into the heart. Aerobic respiration uses glucose from your bloodstream to produce energy. Energy is generated by aerobic respiration which needs oxygen, so when we breathe your body moves the oxygen through the red …show more content…
The respiratory system supplies oxygen to the blood and removes the carbon dioxide out of the blood. When the human heart has blood that is low in oxygen and high in carbon dioxide, it pumps that blood to our lungs through the pulmonary arteries. However when our lungs expand and get new fresh air from the surroundings, that oxygen is then transferred to the blood which is low in oxygen which also sends some of the new carbon dioxide breathed in to our lungs. As the blood now has fresh oxygen it is sent back to the heart and the heart pumps this clean blood throughout the entire
