Maintaining pH Levels SIR Peer assessment Check for the following details in the work of your classmate: Exchange of Gases: One of the primary functions of the respiratory system is to exchange oxygen and carbon dioxide. When you breathe in, your respiratory system brings oxygen into your lungs, where it enters the bloodstream. Simultaneously, carbon dioxide, a waste product, is removed from the blood and expelled when you breathe out. Transport of Oxygen: The circulatory system plays a crucial role in transporting oxygen-rich blood throughout the body. Oxygenated blood is pumped by the heart to various tissues and organs via arteries. This oxygen is vital for cells to perform cellular respiration, which is how they produce energy. Removal of Carbon Dioxide: Once the cells have used oxygen for energy production, they produce carbon dioxide as a waste product. The circulatory system collects this carbon dioxide and transports it back to the lungs. In the lungs, carbon dioxide is removed from the bloodstream and exhaled when you breathe out. Gas Exchange in the Alveoli: In the lungs, tiny air sacs called alveoli are responsible for the actual exchange of gases. Oxygen from the inhaled air diffuses into the bloodstream while carbon dioxide diffuses out of the blood into the alveoli to be exhaled. This exchange occurs due to the close proximity of the circulatory and respiratory systems in the lungs. Maintaining Oxygen Levels: The circulatory system continually monitors oxygen levels in the blood. If oxygen levels drop (as can happen at high altitudes or during strenuous exercise), the heart rate can increase to pump more oxygen-rich blood to the tissues. This is an example of how the circulatory system responds to changes in oxygen demand. Maintaining pH Levels: The respiratory system also helps maintain the body's pH balance. When you breathe, you eliminate carbon dioxide, which can become acidic when dissolved in water. By regulating the removal of carbon dioxide, the respiratory system helps prevent an excessive buildup of acidity in the body. Inquiry Question: What is the impact Learning Objective: Summarise the levels of organization of of lifestyle choices on health? life.
