Biological Fluids
Biological fluids are liquids found within living organisms that play crucial roles in various physiological processes. Examples include blood, saliva, urine, and lymph. These fluids help transport nutrients, remove waste, and facilitate communication between cells, contributing to overall health and homeostasis.
Each type of biological fluid has specific functions and compositions. For instance, blood carries oxygen and nutrients to cells, while urine helps eliminate waste products from the body. Understanding these fluids is essential for fields like medicine and biology, as they provide insights into health, disease, and bodily functions.
