👉 The expanded fluid, also known as plasma, is a vital component of blood and other body fluids. It constitutes approximately 55% of blood volume and is primarily composed of water, but also includes proteins, nutrients, hormones, waste products, and cells. Unlike regular blood, which is thickened by red blood cells, the expanded fluid is more fluid and contains a higher proportion of water. This fluidity allows it to efficiently transport oxygen, nutrients, hormones, and waste products throughout the body, while also playing a crucial role in immune responses and maintaining blood pressure. The plasma's composition is finely regulated by various physiological mechanisms to ensure optimal bodily functions.
