👉 Biofluids are the various bodily fluids that play crucial roles in maintaining homeostasis and supporting physiological functions. These include blood, which transports oxygen, nutrients, hormones, and waste products; lymph, involved in immune response and fluid balance; saliva and mucus, which aid in digestion and protect mucous membranes; sweat, which regulates body temperature; and urine, which eliminates waste products. Each biofluid is essential for the proper functioning of the body's systems, ensuring that cells receive necessary substances and waste products are efficiently removed.
