True or False: Gases can also exert a pressure in a liquid such as blood?

The statement is true. Gases can indeed exert pressure in a liquid, such as blood. This phenomenon is related to the principles of fluid dynamics and gas laws. When a gas is dissolved in a liquid, it occupies space and exerts pressure on the liquid molecules.

In the body, gases like oxygen and carbon dioxide are dissolved in blood plasma. The pressure exerted by these gases is significant, particularly in processes like respiration and gas exchange. The concepts surrounding partial pressures, as described by Dalton's law, allow for a better understanding of how gases behave in a liquid medium.

Additionally, the behavior of gases under pressure can also affect their solubility in liquids, which is crucial for physiological functions such as oxygen transport and carbon dioxide removal in the bloodstream. Therefore, understanding how gases exert pressure in liquids is fundamental in the context of medical gas administration and respiratory physiology.
