👉 Fluid plays multiple crucial roles in biological systems. Primarily, it acts as a vital transport medium, carrying nutrients, oxygen, hormones, and waste products throughout the body. Fluid also serves as a lubricant, reducing friction between surfaces in joints and organs, facilitating smooth movement. Furthermore, it acts as a shock absorber, cushioning internal organs against impacts and maintaining their proper alignment. Additionally, fluid participates in temperature regulation by distributing heat throughout the body and aiding in sweating for cooling. Lastly, it's essential for maintaining blood volume and pressure, ensuring efficient circulation and oxygen delivery to tissues.
