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.
Urine is produced in the kidneys. It flows through tubes called ureters into the bladder. Urine leaves the body through the urethra. The bladder muscle helps you urinate by squeezing to force the urine out. A thin surface layer called the urothelium lines the inside of the bladder. Next is a layer of loose connective tissue called the lamina propria. Covering that tissue is the bladder muscle.
