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 controlled. The bladder is lined by layers of muscle tissue that stretch to hold urine. The normal capacity of the bladder is 400-600 ml.
During urination, the bladder muscles squeeze and two sphincters (valves) open to allow urine to flow out. Urine exits the bladder into the urethra, which carries urine out of the body. Tumors and stones in the bladder can act as plugs and can make it difficult to urinate. In men, the upper portion of the tube that drains the bladder (the urethra) is surrounded by the prostate, which can enlarge and interfere with urination. Infection and inflammation of the prostate can cause symptoms similar to those of a bladder infection.
The human excretory system functions to remove waste from the human body. This system consists of specialized structures and capillary networks that assist in the excretory process. Chakra therapy is based on the belief that due to your own rigidity, past experiences and past belief systems you refuse to let go / release all that which is wasteful and junk, which hinders / blocks the normal process of life.
