Four organs of excretory system are as follows:

1) KIDNEY:

  • It is the main ORGAN for filtration of blood and formation of urine.

  • The structural and functional units of the kidneys are the nephrons.

  • There are almost 3 million nephrons in the two kidneys.

  • The renal arteries provide blood to the kidney , the nephrons filter them and urine is sent to the ureters.

2) Ureters:

  • Ureters are a pair of thin walled, muscular tubes EXTENDING from the kidney to the urinary bladder.

  • Their main function is to transport the urine from the kidney to the urinary bladder.

3) Urinary bladder:

  • The urinary bladder is a LARGE pouch present in the pelvic cavity

  • It is responsible for temporary storage of the urine before getting it excreted.

  • The average volume of urine stored in each cycle is around 200 ml.
