👉 The civilian fluid, also known as blood plasma, is a vital component of the circulatory system that makes up about 55% of total blood volume. It is primarily composed of water, but also contains proteins, nutrients, hormones, and waste products. Unlike red and white blood cells, which are part of the immune system, the civilian fluid serves as a transport medium, carrying oxygen and nutrients to tissues and organs while removing carbon dioxide and other metabolic waste. This fluid plays a crucial role in maintaining homeostasis, regulating temperature, and supporting various physiological processes essential for overall health.
