Final answer:
Hyperproteinemia is a condition in which a tumor in the liver causes excessive secretion of large plasma proteins into the blood. These proteins, being non-penetrating solutes, increase the colloid osmotic pressure in the blood, leading to the movement of water from the interstitial fluid and tissues, causing edema.
Step-by-step explanation:
A tumor in the liver may cause the liver to secrete excessive amounts of large plasma proteins into the blood, leading to a condition called hyperproteinemia. These proteins are non-penetrating solutes, which means they do not dissolve but are dispersed or suspended in their fluid medium, forming a colloid. The presence of these large plasma proteins increases the colloid osmotic pressure in the blood, drawing water from the interstitial fluid and tissues, resulting in edema.
