Which Of The Following Is Not A Part Of The Kidney?

What are the 5 parts of the kidney?

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.

Which of the following is part of the kidney?

Internally, the kidney has three regions—an outer cortex, a medulla in the middle, and the renal pelvis in the region called the hilum of the kidney. The hilum is the concave part of the bean-shape where blood vessels and nerves enter and exit the kidney; it is also the point of exit for the ureters.

What are the 4 layers of the kidney?

The cortex is the outer layer and contains the kidney’s filtering structures. The medulla is the middle layer. It drains the urine into tubes and empties into the renal pelvis. The renal pelvis is the inner layer that leads to the ureter.

What are the 2 parts of the kidney?

Key Points

  • The renal cortex, renal medulla, and renal pelvis are the three main internal regions found in a kidney.
  • Nephrons, masses of tiny tubules, are largely located in the medulla and receive fluid from the blood vessels in the renal cortex.
  • The renal cortex produces erythropotein.

Where is kidney located in our body?

The kidneys are a pair of bean-shaped organs on either side of your spine, below your ribs and behind your belly. Each kidney is about 4 or 5 inches long, roughly the size of a large fist. The kidneys’ job is to filter your blood.

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 papilla in kidney?

Papilla. The renal papilla is the location where the renal pyramids in the medulla empty urine into the minor calyx in the kidney. Histologically it is marked by medullary collecting ducts converging to form a papillary duct to channel the fluid. Transitional epithelium begins to be seen.

Which best describes the movement through the nephron?

Blood is passed into the nephron and removed through the urethra. Some of the materials that exit the blood can be returned to the blood.

What is the pathway of urine through the kidney?

Urine flows through a renal pyramid and exits at the renal papilla, the tip. The renal papilla has collecting ducts, small openings that allow urine to pass through. From the collecting ducts, the urine progresses to the renal pelvis, a widened area of the kidney, and exits through the ureter.

Where do kidney wastes are stored?

Two ureters – (tube-like features) which run from the kidneys to the bladder carrying urine. One bladder – which collects urine from the kidneys, via the ureters, and stores it temporarily. One urethra – through which the urine is excreted out of the body, allowing the bladder to empty and dispose of the waste.

How is urine production and GFR affected by blood pressure?

When blood pressure drops, the same smooth muscle cells relax to lower resistance, increasing blood flow. The vasodilation of the afferent arteriole acts to increase the declining filtrate formation, bringing NFP and GFR back up to normal levels.

What are the 3 inner layers of the kidneys?

The renal cortex, renal medulla, and renal pelvis are the three main internal regions found in a kidney.

What is the other name of artificial kidney?

The mechanical device used to clean the patients blood is called a dialyser, also known as an artificial kidney.

What is the test for kidney function?

Your kidney numbers include 2 tests: ACR (Albumin to Creatinine Ratio) and GFR (glomerular filtration rate). GFR is a measure of kidney function and is performed through a blood test. Your GFR will determine what stage of kidney disease you have – there are 5 stages.

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.
