Final answer:
B) Shorter urethra The increased frequency of UTIs in females is mainly due to their shorter urethra, which allows for easier bacterial contamination from the GI tract.
Step-by-step explanation:
Reason for Increased Frequency of UTIs in Females The reason for the increased frequency of urinary tract infections (UTIs) in females is primarily due to anatomical factors. Specifically, one main reason is the shorter urethra in females compared to males. The female urethra is both shorter and located closer to the anus, which makes it easier for bacteria from the gastrointestinal (GI) tract, particularly Escherichia coli, to enter the urinary tract and cause infections. While hormonal changes can affect susceptibility to UTIs, and factors such as genetics and diet may play a role, it is the anatomy that primarily explains the increased incidence of UTIs in females.
Urinary tract infections (UTIs) are more common in females due to several factors:Shorter urethra: The female urethra is shorter than the male urethra, making it easier for bacteria to travel up the urinary tract and cause an infection.Close proximity to the anus: The urethra in females is located close to the anus, increasing the risk of fecal bacteria contaminating the urethra and causing infection.Hormonal fluctuations: Shifts in estrogen levels, such as during pregnancy or menopause, can make women more susceptible to urogenital infections.These factors, along with others like dietary habits and genetic factors, contribute to the increased frequency of UTIs in females.
