Attempts to correlate structure and function must consider loops of Henle, collecting ducts, vessels, interstitium, and pelvis. What is the function of the renal medulla? The renal medulla develops very differently among species, being more prominent in those with a high urinary concentrating capacity. These and other studies we review show that although blood flow to the inner renal medulla comprises less than 1% of the total renal blood flow, changes in flow to this region can have a major effect on sodium and water homeostasis and on the long-term control of arterial blood pressure. Inside are structures known as nephrons, and they have the responsibility of maintaining the balance of water and salt within the blood. The kidney filters blood and sends waste materials to the bladder to become excreted urine. The renal medulla is a term used for the innermost portion of the kidney.It is divided into several sections known as renal pyramids because of their cone-like appearance.

However, the molecular mechanism remains unclear. The renal medulla is the smooth, inner tissue of the kidney. The renal medulla contains the majority of the length of nephrons, the main functional component of the kidney that filters fluid from blood. The renal pelvis connects the kidney with the circulatory and nervous systems from the rest of the body. The renal medulla is the innermost part of the kidney.The renal medulla is split up into a number of sections, known as the renal pyramids.Blood enters into the kidney via the renal artery, which then splits up to form the segmental arteries which then branch to form interlobar arteries.The interlobar arteries each in turn branch into arcuate arteries, which in turn branch to form interlobular . The adrenal glands, also known as supra-renal . Function The adrenal medulla is mainly responsible for the synthesis of the catecholamines, adrenaline and noradrenaline, but also has other secretory functions such as the production of dopamine.
