👉 Fluids, primarily composed of water but also including electrolytes, proteins, and other dissolved substances, are essential for the proper functioning of living organisms. These fluids facilitate various physiological processes such as nutrient transport, waste removal, temperature regulation, and maintaining cellular homeostasis. In the human body, there are two main types: blood, which circulates throughout the body and transports oxygen, nutrients, hormones, and waste products, and interstitial fluid, which fills the spaces between cells, aiding in the exchange of substances between blood and tissues. Together, these fluids ensure that cells receive what they need to function optimally and maintain overall health and balance.
