What is the difference between renal pyramids and renal medulla

Renal artery carries high-pressure blood. Blood plasma , glucose , salt, and urea are leaked into the nephrons. Glomeruli leak liters of blood in every 24 hours. Most of the fluid is reabsorbed into the blood in the renal medulla. Proximal and distal convoluted tubules are also found in the renal cortex. The re-filtration of glucose occurs in the proximal convoluted tubules while the distal convoluted tubules re-filter salts. Renal cortex also provides space for arterioles and venules as well as glomerular capillaries.

Renal cortex produces hormones called erythropoietin , which facilitates the synthesis of new red blood cells. Renal medulla refers to the inner-most part of the kidney. It is composed of renal pyramids. Renal pyramids are triangular structures, which consist of densely-packed network of nephron structures. The loops of Henle and the collecting tubules are located in the renal pyramids of the renal medulla. The U-shaped portion of a nephron is called the loop of Henle.

It re-filters water, sodium ions, and chloride ions from the filtrate. Renal medulla also contains collecting tubules of the nephrons. Collecting tubules concentrate the final filtrate or urine and transport it to the renal calyces. The distribution of a nephron in the renal cortex and medulla is shown in figure 2. The renal medulla is the interior portion of the kidney where the primary functions of the organ occur: the filtering of waste materials and elimination of fluid from the body.

The kidney filters blood and sends waste materials to the bladder to become excreted urine. What is renal sinus? The renal sinus is a cavity within the kidney which is occupied by the renal pelvis, renal calyces, blood vessels, nerves and fat.

The renal hilum extends into a large cavity within the kidney occupied by the renal vessels, minor renal calyces, major renal calyces, renal pelvis and some adipose tissue. What two structures make up the renal corpuscle? A renal corpuscle is the blood-filtering component of the nephron of the kidney. It consists of a glomerulus - a tuft of capillaries composed of endothelial cells, and a glomerular capsule known as Bowman's capsule.

What is the meaning of renal artery? The renal artery is a blood vessel that carries oxygenated blood from the heart to the kidneys.

It branches off the aorta and travels into the kidney through the hilum. How do you distinguish between the renal artery and the renal vein? Structurally speaking the Renal Artery differ from the Renal Vein in the same as every other Artery does from every other vein except the pulmonary pair.

The Artery is more elastic with thicker walls do withstand the high pressure of blood coursing through it. What does the loop of Henle do? Loop of Henle. Loop of Henle, long, U-shaped portion of the tubule that conducts urine within each nephron q. The principal function of the loop of Henle appears to be the recovery of water and sodium chloride from the urine. Why is it important to maintain a high osmolarity of the renal medulla? Hypoosmotic Renal Medulla High concentrations of sodium and urea in the renal medullary interstitium are essential for the production of concentrated urine.

These create a high osmotic gradient between the renal tubular lumen and interstitium, which is necessary for water reabsorption. Where is filtrate formed? The renal corpuscle is composed of two structures, the glomerulus and the Bowman's capsule. The glomerulus is a small tuft of capillaries containing two cell types. Endothelial cells , which have large fenestrae, are not covered by diaphragms.

The renal column or Bertin column , or column of Bertin is a medullary extension of the renal cortex in between the renal pyramids. It allows the cortex to be better anchored. Each column consists of lines of blood vessels and urinary tubes and a fibrous material.

What is the difference between renal medulla and renal pyramid? Category: medical health brain and nervous system disorders. The medulla is the inner region of the parenchyma of the kidney.

The medulla consists of multiple pyramidal tissue masses, called the renal pyramids , which are triangle structures that contain a dense network of nephrons. What is the renal medulla composed of? Renal Medulla. What is the function of renal artery? What is the function of the calyx?

What does the loop of Henle do? How do you distinguish between the renal artery and the renal vein? Why is it important to maintain a high osmolarity of the renal medulla? Hypoosmotic Renal Medulla.
