This scenаriо invоlves the digestive, circulаtоry аnd respiratory system in a way that lets us revisit that crazy Australian doctor who discovered the bacteria that live in the stomach. If a patient has been diagnosed with stomach ulcers (bleeding canker sores in the stomach), there are a number of different ways they can use to determine if the patient has been infected with H.pylori (the bacteria that was found to live in the stomach). One of the ways is to drink a cocktail that contains an ingredient that this bacterium metabolizes; the metabolite can then be detected in the patient's breath. As the patient drinks this cocktail, the fluid enters the throat, properly called the , before entering the esophagus and finally the stomach. If the bacteria has infected the stomach, they will metabolize one of the ingredients of this cocktail in to a gas. This gas is quickly able to cross the epithelium of the stomach because there is far less of this gas in the blood than in the middle of the stomach. This process of moving from high to low concentration is called . As this gas enters the blood of the stomach, it will enter the blood plasma. This blood will exit the stomach through a . The next organ that this blood (exiting the stomach) will enter is the . Eventually, this blood will enter the heart. As the heart beats, all four chambers of the heart must push to their respective directions, and the timing of these chamber contractions is tightly regulated by two clusters of neurons within the heart. The initial neural stimulus occurs within the , located at the "top" of the heart, in the right atrium, which also happens to be the first chamber of the heart into which the blood with the bacterial metabolic gas enters. As this blood enters the next organ (lungs), it will pass from the blood plasma, into the alveolus to be expelled from the body. As the patient exhales, they are asked to breathe into a container that will capture this bacterial metabolic gas. If the gas is present in their breath, it indicates they have been infected by the bacteria. If there is no bacterial metabolic gas in their breath, they are considered "free" of the bacterium. This test therefore confirms or denies the that this patient has been infected by H.pylori, which is associated with their gastic ulcers.
