24 lip 2023 · A delicate balance exists between renal blood flow and the glomerular filtration rate as changes in one may affect the other. The kidneys function in a wide variety of ways necessary for health. They excrete metabolic waste, regulate fluid and electrolyte balance, promote bone integrity, and more.
This Osmosis High-Yield Note provides an overview of Renal Blood Flow Regulation essentials. All Osmosis Notes are clearly laid-out and contain striking images, tables, and diagrams to help visual learners understand complex topics quickly and efficiently.
• The functional unit of the kidney – the microscopic nephron (1 million in each kidney) • How about 180 litres of plasma filters into the nephrons each day and how most of it is reabsorbed • Autoregulation of renal blood flow which, along with renal nerves and the renin–angiotensin system, influences the rate of filtration
Summary. The kidneys are solid, ‘bean-shaped’ retroperitoneal organs located at vertebral levels T12 to L3. From inside to outside, the kidney is surrounded by the renal capsule, perirenal fat, renal fascia and pararenal fascia.
Despite changes in mean arterial blood pressure (from 80 to 180 mm Hg), renal blood flow is kept at a relatively constant level, a process known as autoregulation (see Chapter 16). Autoregulation is an intrinsic property of the kidneys and is observed even in an isolated, denervated, perfused kidney.

Each kidney is surrounded by a renal capsule, an adipose capsule and renal fascia. Production of renin activates the renin-angiotensin-aldosterone system in the regulation of blood pressure. Erythropoietin is central to the regulation of red blood cell production in bone marrow.
