Short-term fluctuations (years to a few decades) such as the El Nino-NiÃ±o Southern, oscillation The pacific decadal, oscillation The North atlantic, oscillation and The arctic, oscillation represent climate variability rather than climate. changehe most general definition of climate change is a change in the statistical properties (principally its mean and spread) of the climate system when considered over long periods of time, regardless of cause.
The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is made in the kidneys, and travels down two tubes called ureters to the bladder. The bladder stores urine, allowing urination to be infrequent and voluntary. The bladder is lined by layers of muscle tissue that stretch to accommodate urine. The normal capacity of the bladder is 400 to 600 mL.
Your kidneys are the beginning of your urinary system. Your urine is filtered in the kidneys and comes down into your bladder through a ureter, one from each kidney. The urine is held in the urinary bladder until the bladder is emptied, when the urine passes through the urethra and out the urethral opening.
