Renal physiology is the branch of physiology that focuses on the study of the function and regulation of the kidneys. The kidneys play a vital role in maintaining homeostasis in the body by filtering waste products and excess substances from the blood, regulating the balance of electrolytes and fluid, and producing hormones that regulate blood pressure and red blood cell production. Research in renal physiology aims to understand the mechanisms involved in these processes, as well as the impact of various diseases and disorders on kidney function. This research is crucial for developing treatments for kidney diseases and improving overall health outcomes.
