👉 The periodic fluid, also known as the plasma, is a vital component of living organisms, constituting approximately 55% of an adult human body weight. This complex and dynamic fluid is primarily composed of water, but it also includes a variety of dissolved substances such as salts, proteins, lipids, and various cellular components like red and white blood cells, platelets, and nucleic acids. The fluid is characterized by its low viscosity and high electrical conductivity, allowing it to efficiently transport nutrients, hormones, and waste products throughout the body. It acts as a medium for biochemical reactions and plays a crucial role in maintaining homeostasis, immune responses, and overall physiological functions. The periodic nature of this fluid is evident in its constant state of change and interaction with cells, making it a central player in the body's biological processes.
