ANATOMY

Detailed explanation-1: -Urine, a typically sterile liquid by-product of the body, is secreted by the kidneys through a process called urination and excreted through the urethra. Urine is often used as a diagnostic feature for many disease conditions.

Detailed explanation-2: -To imply that urine is sterile would mean that urine does not contain any bacteria or other living organisms.

Detailed explanation-3: -Adult human urine is not sterile. The resident bacterial community may contribute to urinary health and disease in undiscovered ways. Bacterial genomic sequencing and expanded urine cultures techniques are major complementary tools for scientific exploration in urologic research.
