Question: Which Is The Area Of The Kidney That Includes The Cortex And Medulla?

Which is the area of the kidney that includes the cortex?

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.

Where is the medulla of the kidney?

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 renal cortex and renal medulla?

Each kidney consists of an outer renal cortex, an inner renal medulla, and a renal pelvis. Blood is filtered in the renal cortex. The renal medulla contains the renal pyramids, where urine formation takes place. Urine drains from the renal pelvis into the ureter.

What is the indentation where the renal artery enters and the renal vein and ureter exit the kidney?

It is roughly bean-shaped with an indentation, called the hilum, on the medial side. The hilum leads to a large cavity, called the renal sinus, within the kidney. The ureter and renal vein leave the kidney, and the renal artery enters the kidney at the hilum.

What are the 7 functions of the kidneys?

The 7 functions of the kidneys

  • A – controlling ACID-base balance.
  • W – controlling WATER balance.
  • E – maintaining ELECTROLYTE balance.
  • T – removing TOXINS and waste products from the body.
  • B – controlling BLOOD PRESSURE.
  • E – producing the hormone ERYTHROPOIETIN.
  • D – activating vitamin D.

What is the correct branching sequence of arteries in the kidney?

The renal artery first divides into segmental arteries, followed by further branching to form multiple interlobar arteries that pass through the renal columns to reach the cortex. The interlobar arteries, in turn, branch into arcuate arteries, cortical radiate arteries, and then into afferent arterioles.

What is the main function of the medulla in the kidney?

The main function of the medulla is to regulate concentration of the urine. The urine flows from the collecting ducts into the renal calyces and pelvis, which undergoes unidirectional peristaltic movements to allow drainage of the urine into the downstream ureter and bladder.

What structures can be found in the medulla of the kidney?

These structures include the vasa rectae (both spuria and vera), the venulae rectae, the medullary capillary plexus, the loop of Henle, and the collecting tubule. The renal medulla is hypertonic to the filtrate in the nephron and aids in the reabsorption of water. Blood is filtered in the glomerulus by solute size.

What does the medulla kidney?

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 present in renal cortex?

The cortical labyrinth contains the glomeruli, proximal convoluted tubule (PCT), macula densa, distal convoluted tubule (DCT), connecting tubule, initial collecting duct (ICT), interlobular arteries, and the afferent and efferent capillary networks.

How do kidneys function?

Why Are the Kidneys So Important? Most people know that a major function of the kidneys is to remove waste products and excess fluid from the body. These waste products and excess fluid are removed through the urine. The production of urine involves highly complex steps of excretion and re-absorption.

Is the medulla deep to the cortex of the kidney?

The renal cortex is granular tissue due to the presence of nephrons—the functional unit of the kidney—that are located deeper within the kidney, within the renal pyramids of the medulla.

What organ system does the kidney belong to?

The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra. The body takes nutrients from food and converts them to energy.

What part of the body is renal?

Renal system, in humans, organ system that includes the kidneys, where urine is produced, and the ureters, bladder, and urethra for the passage, storage, and voiding of urine.

Where does the kidney filter the blood quizlet?

Filtration: blood is delivered from the aorta the very outer parts of the kidneys. accepts filtered blood from the glomerulus. This filtrate then passes through the long and windy (microscopic) nephron, and most solutes and fluid are reabsorped into the peritubular capillaries.
