What are the main things found in the plasma of the blood?

The plasma of the blood primarily consists of water (about 90%), which serves as a solvent for various substances. It contains electrolytes, such as sodium and potassium, proteins like albumin and fibrinogen, hormones, nutrients (like glucose and amino acids), waste products (such as urea), and gases (like carbon dioxide). These components play crucial roles in maintaining blood volume, transporting substances, and supporting immune function.
