Question

Select the statement that most accurately characterizes genitourinary tract biota.

• The vaginal harbors normal biota that changes during puberty and the childbearing years.

• The microbiota of the male urethra is constant throughout life.

• The composition of biota is similar on a circumcised versus an uncircumcised penis.

• Biota travel a longer distance from the urethra to the bladder in females versus males.

Answer 1

Answer:

The vaginal harbors normal biota that changes during puberty and the childbearing years.

Explanation:

Biota of women in childbearing years prevents establishment and invasion of microbes that might harm the fetus through acididc pH, mucus secretions and secretory IgA

The microbiota of the male urethra is not constant throughout life. Exact microbial composition varies among men and women.

The composition of biota is similar on a circumcised versus an uncircumcised male reproductive part. Circumcision changes the composition of the known normal biota of the penis. Biota in the uncircumcised malre reproductive part can stimulate the inflammatory response and can increase susceptibility to infection

Female urethra is short about 3.5cm long than male urethra. So biota travel a longer distance from the urethra to the bladder in males versus females
