Modeli urinarnog sistema 3d je sistem organa koji formiraju, akumuliraju i izlučuju urin kod ljudi. Sastoji se od para bubrega, dva uretera, mokraćne bešike i uretre. Analog beskralježnjaka je Nefridium.

The kidneys are the organs of a bean-shaped form, measuring 10–12 cm in length, 5–6 cm in width, and 3–4 cm in thickness, located in the retroperitoneal space, near the lumbar spine. The kidneys are surrounded by perinephral fat; up and several anterior to the kidneys are the adrenal glands. The kidney performs many functions – the concentration of urine, the maintenance of electrolyte and acid-base homeostasis. The kidney secretes and reabsorbs (reabsorbs) electrolytes (sodium, potassium, calcium, etc.) under the control of local and systemic hormones (renin-angiotensin system).

Kod ljudi, mokraćna bešika je šuplji mišićni organ koji se nalazi retroperitonealno u karlici. Mokraćni mjehur služi za nakupljanje urina. Kapacitet mokraćne bešike je u prosjeku 500-700 ml i podložan je velikim individualnim fluktuacijama. Veličina mjehura varira u zavisnosti od sadržaja istezanja. U odsustvu bolesti, mokraćna bešika može sigurno držati 300 ml urina za 2-5 sati.

The final part of the excretory system is the urethra (urethra). The urethra differs in men and women – in men it is long and narrow (22-24 cm long, up to 8 mm wide), and in women – short and wide. In the male body, ducts that carry sperm also open into the urethra.
