muscle of the urinary bladder
basic functional unit of a kidney
micturition
fibrous tunic of the kidney
the outer region of the kidney
consists of 6 to 18 renal pyramids
dense outer layer of the kidney

region of the juxtaglomerular complex
site of entry or exit for the renal artery and vein
Introduction:
The kidney is the major organ of the urinary system that filters the waste material from the blood and produces urine. Each nephron of the kidney consists of two parts, one is renal corpuscle and the second is renal tubule. This function is performed with the help of nephrons, which act as the functional unit in the kidney. They are present in millions of numbers in the kidneys.

- As a person ages, nephron tubules lose some of their ability to concentrate urine. What is the effect of this change?arrow_forwardWhy is excretion important in order to achieve osmotic balance?arrow_forwardAs the text noted, two-thirds of the water and solutes that the body reclaims by reabsorption in nephrons occurs in the proximal tubule. Proximal tubule cells have large numbers of mitochondria and demand a great deal of oxygen. Explain why.arrow_forward
