Why respiration obey Dalton law?

Respiration obeys Dalton's Law because it involves the exchange of gases, where each gas in a mixture exerts its own partial pressure independently of the others. In the lungs, oxygen and carbon dioxide are exchanged based on their partial pressures, allowing for efficient gas transfer. Dalton's Law states that the total pressure of a gas mixture is the sum of the partial pressures of its individual gases, which is crucial for understanding how oxygen is absorbed into the blood and carbon dioxide is released. Thus, the principles of Dalton's Law are essential for the mechanics of respiration.
