    Introduction: The transport system in our body that carries blood is known as the circulatory system. This system allows the blood to carry essential nutrients such as amino acids, oxygen, and hormones to the cells in all parts of our body to ensure they are able to maintain body temperature and pH known as homeostasis. The oxygen-rich blood enables cellular respiration to occur efficiently which is vital for humans to continue to survive. It also carries cellular waste such as carbon dioxide which

    The Heart and Circulatory System The regular heart beat and pulse is produced by contractions of the heart muscle during the cardiac cycle. These contractions are caused by an electrical stimulus called the cardiac impulse. This natural pacemaker of the heart, called the Sinoatrial node, is located in the Right Atrium. The electrical impulse leaves the Sinoatrial node and travels to the right and left Atria, causing them to contract together. After contraction, there is a period of

It was also hypothesized that exercise will cause the heart rate to temporarily increase. As for the final hypothesis involved in these experiments, it was said that during an exhale the heart rate will be lower

    have a circulatory system as their gas exchange system. It operates by the oxygen that is diffused being delivered to respiring body cells and returning with carbon dioxide to the lungs due to the blood vessels lining the alveoli transporting these gases. As diffusion would take much longer to reach the cells in a much larger organism, the blood flow through the capillaries guarantees that the oxygen reaches the distant cells more efficiently. This is why mammals require a transport system due to
