Question

What processes take place during the period when the blood enters the kidneys till the urine leaves the body?

Answer 1

Hey friend here is your answer_
Blood flows to the kidney through the renal artery. Once in the kidney the blood flows through a series of smaller and smaller arteries until it gets to the glomerulus. The glomerulus filters blood and to be very simplistic creates a filtrate of the blood or "urine". This urine then flows through a series of progressively bigger tubules and ducts until it gets to the renal pelvis. At this point urine exits the kidney, it enters the ureter (long tube connecting kidney and bladder), and flows into the bladder where it is held until one desires to urinate. At this time urine flows out of the bladder and into the urethra. The urethra connects the bladder to the outside of the body.
Hope this helps you.
