________minor calyx
________renal pyramid
________renal artery

- A urinary tract infection (UTI) is an infection of any of the urinary tract structures: kidneys, ureter, bladder, or urethra. Considering the differences in the male and female anatomy and that the bacteria that cause UTIs are often found in the feces, explain why females are more likely to contract a UTI. Females are more likely to contract a UTI because the opening of the urinary tract is located closer to the opening of the digestive tract, allowing fecal bacteria to get into the urinary tract more easily. Females are more likely to contract a UTI because their urinary tract organs are more compact and located more inferiorly in the pelvic cavity. Males get fewer UTIs because their urethra is longer and cleansed by secretions of the accessory reproductive glands. Males urinate more often standing up, so gravity helps prevent colonization of the urinary tract.arrow_forwardDescribe in details, the anatomy of the following structures of the urinary system: 1.

The first capillary bed of the kidneys is the peritubular capillaries,which are fed by the afferent arteriole and drained by the efferent arteriole. d.
