How does temperature affect gas solubility in blood?

• A. Increased temperature increases gas solubility
• B. Decreased temperature decreases gas solubility
• C. Increased temperature decreases gas solubility
• D. Temperature has no effect on gas solubility

Answer: (C)

When considering the relationship between temperature and gas solubility in blood, the correct answer is that increased temperature decreases gas solubility. As temperature rises, the kinetic energy of gas molecules also increases, which leads to a greater tendency for the gas to escape from the liquid (in this case, the blood) into the atmosphere. This phenomenon is due to the fact that higher temperatures cause the gas molecules to move more vigorously, making it less likely for them to remain dissolved in the liquid phase. In biological systems, such as blood, this principle is particularly important when examining how gases like oxygen and carbon dioxide behave under different temperature conditions. For instance, during exercise or states of fever where body temperature rises, the solubility of oxygen in blood would decrease, potentially affecting oxygen transport to tissues. Understanding this insight into gas solubility is crucial for various physiological processes, especially in scenarios like hyperthermia or during conditions of elevated metabolic activity, where temperature changes can impact gas exchange efficiency in the lungs and within tissues.
