What is the cortex of the kidney?
The renal cortex is the outer part of the kidney. It contains the glomerulus and convoluted tubules. The renal cortex is surrounded on its outer edges by the renal capsule, a layer of fatty tissue. Together, the renal cortex and capsule house and protect the inner structures of the kidney.
What is the cortex of the kidney made of?
Mammalian kidneys have a somewhat granular outer section (the cortex), containing the glomeruli and convoluted tubules, and a smooth, somewhat striated inner section (the medulla), containing the loops of Henle and the collecting tubules.
What is histology of kidney?
The nephron loop is the U-shaped bend of a nephron which extends through the medulla of the kidney. Histologically, it consists of two parts; thin descending and thin ascending limbs. Both limbs are composed of simple squamous epithelium.
What is the function of the cortex region of the kidney?
The cortex provides a space for arterioles and venules from the renal artery and vein, as well as the glomerular capillaries, to perfuse the nephrons of the kidney. Erythropotein, a hormone necessary for the synthesis of new red blood cells, is also produced in the renal cortex.
Is the medulla deep to the cortex of the kidney?
Renal medulla – deep to the cortex and consists of 6-18 distinct triangular structures. Cortical radiate arteries – each arcuate artery gives off a number of cortical radiate arteries. 2. Renal tubule – a long tubular passageway that begins at the renal corpuscle and empties into the collecting system.
What is medulla in kidney?
The mature renal medulla, the inner part of the kidney, consists of the medullary collecting ducts, loops of Henle, vasa recta and the interstitium. The unique spatial arrangement of these components is essential for the regulation of urine concentration and other specialized kidney functions.
Is the glomerulus in the medulla or cortex?
The kidney is covered by a connective tissue capsule. The outer part of the kidney is the cortex and the inner part is the medulla. Within the cortex are glomeruli and tubules.
What is the function of renal medulla and cortex?
Function. Renal Cortex: Renal cortex filters blood. Renal Medulla: Renal medullas regulates water and salts in the blood.
What separates the renal cortex from the medulla?
The renal columns
The renal columns are connective tissue extensions that radiate downward from the cortex through the medulla to separate the most characteristic features of the medulla, the renal pyramids and renal papillae.
What is the relationship between the renal cortex and medulla?
The renal cortex is a space between the medulla and the outer capsule. 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.
What is the medullary interstitium of kidney?
The medullary interstitium is the tissue surrounding the loop of Henle in the medulla. It functions in renal water reabsorption by building up a high hypertonicity, which draws water out of the thin descending limb of the loop of Henle and the collecting duct system.
What is the function of the cortex in a kidney?
The cortex provides a space for arterioles and venules from the renal artery and vein, as well as the glomerular capillaries, to perfuse the nephrons of the kidney. Erythropotein, a hormone necessary for the synthesis of new red blood cells, is also produced in the renal cortex.
What is the normal renal cortex measurement?
– (a) Longitudinal view with length measurement – (b) Transverse view of the upper pole – (c) Transverse view of the lower pole – (d) Transverse view of the renal pelvis – (e) View showing the liver and right kidney on the same image, if possible
What causes renal cortical thinning?
acidosis
How does acute renal failure is diagnosed?
Pain in the side and back that may travel to the lower abdomen or groin
