This type of exercise includes 10-second bursts of high intensity followed by 30-second recovery periods. The digestive system breaks the ingested food down into tiny units called amino acids (proteins), glucose (carbohydrates) and fatty acids (fats). As the work of the muscle increases, more and more ATP gets consumed and must be replaced in order for the muscle to keep moving.. Because ATP is so important, the body has several different systems to create ATP. After both the stored ATP and the stored phosphocreatine in the muscle cells are used up, the body needs to produce more ATP ⦠About 12 chemical reactions take place to make ATP under this process, so it supplies ATP at a slower rate than the phosphagen system. Getting Energy from FoodâYour Digestive System 83 This picture of the digestive system shows the organs that con-nect to each other to form the digestive âtubeâ. Each system uses different starting fuels, each provides ATP ⦠These tiny units are absorbed into the bloodstream and transported into the cells. Anatomy of the Digestive System. It is used to build the organic molecules that are required for cells and tissues; it provides energy for muscle contraction and for the transmission of electrical signals in the nervous system. Alactic exercise utilizes the ATP-PC energy system to increase its efficiency. However it has larger fuel supplies (a bigger fuel tank) and doesnât burn all its fuel as quickly as the ATP-PC system, so it doesn't fatigue as quickly as the ATP-PC system.. In the body, the primary final agent to produce energy is called adenosine triphosphate (ATP). This equation states that glucose, in combination with ATP (the energy source), NAD + (a coenzyme that serves as an electron acceptor), and inorganic phosphate, breaks down into two pyruvate molecules, generating four ATP moleculesâfor a net yield of two ATPâand two energy-containing NADH coenzymes. When ATP is broken ⦠These organs include the mouth, esophagus (i-SAHF-uh-guhs), stomach, small intestine, large intestine, rectum, and anus. ATP is required for the biochemical reactions involved in any muscle contraction. The anaerobic glycolytic system produces a lot of power, but not quite as much or as quickly as the ATP-PC system. Looking at The system can still act rapidly and produce enough ATP to last about 90 seconds. Circulatory system, respiratory system, digestive system, excretory system, immune systemâ¦so many systems are there and you may be wondering how they work together. This system does not need oxygen, which is handy because it takes the heart ⦠The cell can use the tiny units as fuel to convert ADP into ATP and for building and strengthening all ⦠In 1977, Forrester and Williams 15 observed the release of ATP from cells in the cardiovascular system and the release of ATP has since been shown in all major cell types of the vessel wall including endothelial cells, 9, 16â19 vascular smooth muscle cells, 11, 20 perivascular sympathetic nerves, 21â24 and circulating ⦠Well, how the digestive, respiratory, and circulatory work together will be mainly discussed here to help understand your body better. ATP, which stands for adenosine triphosphate, is the sole source of energy for all human metabolism, yet very little of this fuel is actually stored in the body. The NADH that is produced in this process will be used later to produce ATP ⦠Metabolism basically refers to all the chemical reactions within the body used to produce energy. When the amount of ATP is available in excess of the bodyâs requirements, the liver uses the excess ATP and excess glucose to produce ⦠This involves a complex set of processes that convert fuels into specialised compounds loaded with energy. Instead, the body has three different systems of ATP production: ATP-PC, anaerobic glycolysis, and aerobic phosphorylation. Your digestive and circulatory systems are among the large organ systems in your body. The digestive system consists of the alimentary canal (a hollow tube extending from mouth to anus) and several accessory digestive organs (Figure 14.1).The wall of the alimentary canal has four main tissue layers mucosa, submucosa, muscularis externa, serosa (Figure 14.2).
