👉 Fluids in the body are a complex mixture of various substances that play crucial roles in maintaining homeostasis and supporting physiological functions. Primarily, these include water, electrolytes like sodium, potassium, calcium, and magnesium, as well as nutrients such as glucose, amino acids, and lipids. Water constitutes about 60% of an adult's body weight and is vital for hydration, temperature regulation, and nutrient transport. Electrolytes help maintain proper fluid balance, nerve function, and muscle contractions. Together, these components form the blood, which transports oxygen and nutrients while removing waste products. Additionally, bodily fluids like saliva, mucus, and sweat contribute to lubrication, protection, and temperature control. The diversity of fluids ensures that the body can adapt to various conditions and perform essential functions efficiently.
