Abstract
Urin je tekući nusprodukt koji se izlučuje iz bubrega procesom koji se naziva uriniranje, odnosno mokrenje. Nastaje procesom filtracije iz viška vode i otpadnih metaboličkih produkata te je glavna izlučevina mokraćnog sustava. Regulacijom uklanjanja otpada putem urina, osmolalnosti plazme i volumena krvi, tijelo koristeći samo jedan proces obavlja mnoge funkcije. Sustav za stvaranje, pohranu i prijenos urina se naziva mokraćni sustav kojeg čine različiti organi, mišići i živci koji djeluju kao cjelina. Dijelovi mokraćnog sustava su: dva bubrega, dva mokraćovoda, mjehur i mokraćna cijev. Bubrezi su organi koji imaju oblik graha i veličine su stisnute šake te se u njima stvara urin. Svaki bubreg je preko mokraćovoda, cijevi koja crpi urin iz bubrega, povezan s mjehurom gdje se urin doveden mokraćovodom skladišti prije nego se ukloni iz organizma. Kada se u mjehuru nakupi dovoljna količina urina, određeni živci šalju signal mozgu da je vrijeme za uriniranje pri čemu se mjehur prazni preko mokraćne cijevi koja je smještena na dnu mjehura. S obzirom da je u normalnim uvjetima urin sterilan, odnosno ne sadrži bakterije, koristi se u dijagnostičke svrhe kako bi se isključili ili otkrili poremećaji rada bubrega i mokraćnog trakta. Upravo se preko različitih fizikalnih i kemijskih komponenata daje uvid u metaboličke procese koji se odvijaju u organizmu te na temelju toga uspostavlja određena dijagnoza. To se postiže analizom urina koja uključuje provjeru koncentracije, sadržaja i izgleda urina, odnosno različitih fizikalnih i kemijskih svojstava.
Abstract (english)
Urine is a liquid byproduct which is excreted from kidneys by a process called urination. It is formed by filtration of excess water and waste metabolic products and represents the main secretion of the urinary tract. By waste disposal regulation through urine, plasma osmolality and blood volume, body performs many functions using only one process. Urinary system is the system that produces, stores and eliminates urine and consists of different organs, muscles and nerves that make one complex. Urinary system consists of two kidneys, two ureters, bladder and urethra. The kidneys are bean-shaped organs each about the size of a fist where urine is formed. Each kidney is connected to a bladder by ureter, tube that draws urine from kidneys, where urine is stored before it is disposed from organism. When the bladder is filled with enough amounts of urine, the nerves are sending a signal to the brain for urination while bladder empties through urethra which is located at the bottom of the bladder. Under normal conditions, urine is sterile and does not contain any bacteria so it is used in diagnostic purposes to exclude or reveal kidney and urinary tract disorders. It gives insight into metabolic processes through different physical and chemical components that take place in organism and based on that, diagnosis is being set up. That is achieved with urinanalysis which includes analysis of urine concentration, content and appereance, also analysis of different physical and chemical properties.
