Before revision: Liver enlargement and the prolonged need for RBC production results in decreased ability to make other proteins, such as albumin, and this decreases the plasma colloid oncotic pressure leading to leakage of fluid into tissues and body cavities, termed hydrops fetalis.
After revision: Liver enlargement and the prolonged need for RBC production results in decreased ability to make other proteins, such as albumin, and this decreases the plasma colloid osmotic pressure (the fluid-retaining ability of blood plasma) leading to leakage of fluid into tissues and body cavities, termed hydrops fetalis.
