large proteins
Proteins are found in plasma but are generally not present in the tubular fluid of the kidneys due to their large size. However, small proteins may be filtered into the tubules under certain conditions.
Large proteins, such as albumin and globulins, are typically found in plasma but are not usually found in the tubular fluid of the kidneys due to their size and selective reabsorption by the renal tubules.
In plasma, substances like proteins (e.g., albumin) are present, but they are typically not found in tubular fluid because they are too large to pass through the glomerular filtration barrier in the kidneys. Additionally, certain hormones and large molecules are also retained in the plasma and not usually found in the tubular fluid. This selective filtration helps maintain the proper composition of blood and prevents the loss of essential proteins.
Serum is a fluid similar to plasma but lacks plasma proteins like fibrinogen. Serum is obtained by allowing blood to clot, which results in the removal of fibrinogen and other clotting factors that are present in plasma.

serum
Interstitial fluid, plasma, and transcellular fluid.
Serum is a fluid similar to plasma but lacks plasma proteins like fibrinogen. Serum is obtained by allowing blood to clot, which results in the removal of fibrinogen and other clotting factors that are present in plasma.
The primary differences between plasma and interstitial fluid involve (1) the concentrations of dissolved proteins,because plasma proteins cannot cross capillary walls, and (2) the levels of respiratory gases (oxygen and carbon dioxide), due to the respiratory activities of tissue cells.
Gingival fluid is fluid containing plasma proteins. When there is gingival inflammation more gingival fluid is produced. Gingival fluid is sometimes also called crevicular fluid.
They allow movement of salts and sugars through the plasma membrane

In starvation, when the body begins to cannibalize protein ions from plasma proteins, the osmotic pressure in the plasma decreases. This is because proteins, particularly albumin, play a crucial role in maintaining oncotic pressure, which helps keep fluid within the blood vessels. As protein levels drop, the ability of the plasma to retain fluid diminishes, potentially leading to edema and fluid imbalance in the body. Consequently, the overall osmotic pressure of the plasma becomes reduced.
