The lower urinary tract (LUT) is the collection of organs which convey the urine formed within the kidneys to the exterior of the body. Urine is not altered in this part of the system in species other than the horse (where mucous is added) but instead the function of the LUT is to collect and store urine until enough of it is collected for release to become necessary.  This gives the animal urinary continence.  Three major structures make up this tract;  the ureters, the bladder and the urethra which are formed from the horizontal division of the primitive hind gut in the cloacal region during [[Developmental_Anatomy_of_the_Kidneys_and_Urinary_Tract_-_Anatomy_%26_Physiology#Lower_Urinary_Tract|development]]. [[Normal Composition of Urine - Anatomy & Physiology|Urine]] gives valuable information to the veterinary practitioner regarding kidney function and other urinary system abnormalities such as crystals, casts and infections.
