An uretra (gikan sa Greek οὐρήθρα – ourḗthrā) iyo an sarong tubo na nagkokonektar sa pantog pasiring sa urinary meatus para sa paghale sa ihi gikan sa hawak kan mga babayi asin mga lalaki. Sa mga tawong babayi asin iba pang mga primates, an urethra nagkokonektar sa urinary meatus sa ibabaw kan putay, kun saen sa mga marsupials, an uretra kan mga babayi nagbabawas sa urogenital sinus.[1]
Piggagamit kan mga babayi an saindang urethra solamente sa pag-ihi, alagad an mga lalaki piggagamit an saindang urethra sa pag-ihi asin ejaculation.[2] An panluwas na urethral sphincter iyo an sarong striated muscle na nagtotogot sa bakong boluntaryong kontrol sa pag-ihi.[3] An internal sphincter, binilog kan bakong boluntaryong smooth muscles sa gilid kan bladder neck asin urethra, nagreresibi nin saiyang nerve supply huli sa sympathetic division kan autonomic nervous system.[4] An internal sphincter is presente sa mga lalaki asin sa mga babayi.[5][6][7]
