The liver is the organ that secretes most of the plasma proteins, including albumin, globulins, and clotting factors. These proteins play important roles in maintaining fluid balance, transporting substances in the blood, and clotting blood when needed.
The pancreas secretes digestive enzymes that help break down carbohydrates, fats, and proteins in the small intestine. This organ plays a crucial role in the chemical digestion of food.
The pancreas secretes the most potent digestive enzymes in the body. These enzymes help break down carbohydrates, proteins, and fats in the small intestine to be absorbed by the body.
Plasma protein synthesis primarily occurs in the liver. Hepatocytes, the main cells of the liver, are responsible for producing most plasma proteins, such as albumin, globulins, and clotting factors. These proteins are then released into the bloodstream and contribute to various functions within the body.
Approximately 55% of blood is the watery part known as plasma. Plasma contains water, electrolytes, proteins, hormones, and waste products.
Many functions of the plasma membrane are carried out by proteins embedded within the lipid bilayer. These proteins include transporters for moving molecules in and out of the cell, receptors for cell signaling, and enzymes that catalyze chemical reactions. The lipid bilayer itself provides a barrier that separates the cell's interior from the external environment.
