Hi! This is the urinary system!
How can I help you today?
Yes please, what is this thing called the urinary system?
The organs, tubes, muscles and nerves that work together
to create, store and carry urine is the urinary system!
and don't these organs are tubes have any name?
Sure they do!
The main part of the urinary system are... the kidneys!
The kidneys are bean shaped organs about the size of your fist
They are near the middle of the back
just below the rib cage
The ureterers! tubes leadind from the kidneys to the bladder
The bladder!. The bladder is a holow muscular organ
she's like a big balloon
and the urethra! the tube leading from the bladder
to the exterior of the body
The kidneys filter the blood and remove waste producing a liquid called urine
Some people call it pee!
but remember the clean blood leaves the kidneys
and travels thoughout the body
Each kidney has millions of urine making units
known as nephrons! that filters the blood that flows through the kidneys
as the kidneys do that thing the urine is carried by two thin tubes called ureters
down to the bladder
Muscles in the ureter walls constantly tighten and relax to force urine downwards away from the kidneys
Small amount of urine are emptied into the bladder from the ureters about every 10 to 15 seconds
The bladder is the storage sac that holds the urine
When the bladder is about halfway full your body tells you to go to the bathroom
then the bladder muscles go into action and the urine
is released from the body through a tube called the urethra
Let me tell something that is really interesting
