Question

Which of the following statements regarding the urogential tracts of humans is incorrect?

A. The male urinary tract and male reproductive tract have the same type of normal flora

B. The female urinary tract and female reproductive tract have the same type of normal flora

C. The male reproductive tract is largely sterile except for the portion nearest the external opening, whereas the female reproductive tract is generally well-colonized with normal flora.

D. Both the male urinary tract and the female urinary tract are largely sterile except for the portion of the urethra nearest the urethral opening

Explanation / Answer

The genitourinary system or urogenital system is the organ system of the reproductive organs and the urinary system.

The organs of the male reproductive system are specialized for the following functions:

The male reproductive anatomy includes internal and external structures.

Most of the male reproductive system is located outside of the man’s abdominal cavity or pelvis.

The pelvis is male organ for sexual intercourse. It has three parts: the root, which attaches to the wall of the abdomen; the body, or shaft; and the glans, which is the cone-shaped end. The glans, which also is called the head, is covered with a loose layer of skin called foreskin. (This skin is sometimes removed in a procedure called circumcision.) The opening of the urethra, the tube that transports semen and urine, is at the tip of the glans It also contains a number of sensitive nerve endings.

Semen, which contains sperm, is expelled (ejaculated) through the end of the pelvis when the man reaches sexual climax (orgasm). When the pelvis is erect, the flow of urine is blocked from the urethra, allowing only semen to be ejaculated at orgasm.

The loose pouch-like sac of skin that hangs behind. It contains the testicles (also called testes), as well as many nerves and blood vessels. It has a protective function and acts as a climate control system for the testes. For normal sperm development, the testes must be at a temperature slightly cooler than the body temperature. Special muscles in the wall allows it to contract (tighten) and relax, moving the testicles closer to the body for warmth and protection or farther away from the body to cool the temperature.

Testicles (testes) — The testes are oval organs about the size of very large olives, secured at either end by a structure called the spermatic cord. Most men have two testes. The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.

Epididymis — The epididymis is a long, coiled tube that rests on the backside of each testicle. It functions in the carrying and storage of the sperm cells that are produced in the testes. It also is the job of the epididymis to bring the sperm to maturity, since the sperm that emerge from the testes are immature and incapable of fertilization. During sexual arousal, contractions force the sperm into the vas deferens.

The internal organs of the male reproductive system, also called accessory organs, include the following:

The female reproductive tract is another organ system in which the normal microbial flora is developmentally and age related. As the infant passes through the birth canal she picks up microorganisms representative of the adult reproductive tract. The pH of the infant of about one month of age is about 7.0 and the microbial flora is quite diverse with no single organism being dominant. Among the most common organisms isolated areStaphylococcus epidermidis, and coryneform bacteria and secies of the genera Peptostreptococcus, Bacteroides, Clostridium and Eubacterium(Wilson, 2005). After puberty the lining of the uterus begins to secrete glycogen, a polysaccharide that favors the colonization and growth of lactobacilli. The Lactobacilli are typically the dominant but far from the only organisms present in the uterus these include the Lactobacilli, Staphylococci, Coryneform bacteria Candida, Streptococcus spp. Gardnerellavaginalis, Ureaplasma spp., Bacteroides, Veillonella spp., Bifidobacterium spp., and Clostridium.  

So based on the explanation that is provided it is said that option C would be the correct answer for this.
