👉 Prospective fluid refers to the fluid that anticipates and prepares for future physiological changes within the body, particularly in response to anticipated stressors or demands. This fluid is often associated with the body's adaptive mechanisms, such as increased blood volume, enhanced cardiac output, and elevated plasma protein concentrations, all aimed at optimizing performance and maintaining homeostasis during periods of increased activity or stress. Essentially, it's the body's preparatory fluid that ensures it is ready to handle upcoming challenges efficiently.
