CHAPTER 12 GENITOURINARY SYSTEM

The urinary system functions to eliminate nitrogenous wastes (left-over after protein metabolism) and excess electrolytes (important in fluid balance) from the bloodstream. In the male, this system also shares structures with the reproductive system.

Urine is produced in the kidneys, two bean-shaped structures. Kidneys are composed of two layers of tissue; the outer one is called the cortex and the inner one is called the medulla. After urine is formed, it collects in a hollow chamber in the kidney called the pelvis. From here it flows into the ureters, tubes which lead from the kidney to the urinary bladder. The bladder stores urine until voiding, or urination, occurs. At this time, urine leaves the kidney and passes through the urethra and out of the body through the urinary meatus.

The male reproductive system functions to produce sperm and male sex hormones. The two testes produce sperm, which mature in the epididymis. When ejaculation takes place, sperm travel through the two vas deferens to the urethra and leave the body through the urinary meatus. Along their pathway, structures contribute fluid to semen. These are the seminal vesicles, the prostate gland, and Cowper’s glands.

When you examine the diagram of the urinary system on page 222, you will see that the prostate gland in the male completely surrounds the urethra. If the prostate gland becomes enlarged, a very common occurrence in older men, it can obstruct the flow of urine. There are two causes of prostate enlargement, benign prostatic hypertrophy (not cancer) and cancer of the prostate. It is important to detect prostate cancer in its early stages when it is more curable. There are two tests commonly used for this purpose. One is the digital rectal exam (DRE), and the other is a blood test for prostate specific antigen (PSA).

During fetal development, the testes develop inside the abdominal cavity, then descend into the scrotum before birth. Sometimes a male baby is born with testes still in the abdominal cavity, a condition called cryptorchidism (crypt means hidden). If these fail to descend spontaneously, then this condition is corrected surgically.

The female sex cell, an ovum (or egg) is produced in the ovaries. Generally only one ovum is matured and released each month; the right and left ovaries alternate production. The ovum is released into the abdominal cavity during ovulation and picked up by the end of a Fallopian tube (oviduct), which carries the egg to the uterus. If not fertilized, a process which occurs in the Fallopian tube, the egg will be shed from the uterus during menstruation through the cervix uteri and the vagina. The onset of menstruation in a girl is called menarche, and the cessation of menstruation in an older woman is called menopause.

The rounded top of the uterus is the fundus. The external female genitals are called vulva.

If an ovum is fertilized, pregnancy, or gestation, occurs. When fetal development is complete, labor begins the process of expelling the fetus from the uterus. There are three stages in labor. The process ofcontractions to expand the cervix uteri so the fetus can pass through is called dilation. Then comes expulsion of the fetus and of the afterbirth or placenta. The process of birth itself is called parturition.

In some women uterine lining tissue, called endometrium, occurs outside the uterus, frequently in the abdominal cavity. The presence of this ectopic (out of place) endometrial tissue is called endometriosis.

A number of infections can occur in the reproductive system. One seen in women is vaginal inflammation (vaginitis) caused by the yeast Candida. The textbook (and some medical professionals) call this candidiasis. A more current term for this infection is candidosis.

Other infections are transmitted during sexual intercourse. These include gonorrhea, which causes inflammation in the reproductive tract and in other tissues and can cause infertility; syphilis, which causes lesions on the genitals and spreads to tissue throughout the body; genital herpes, which causes recurring lesions in the reproductive system and on the genitals; chlamydia, which causes inflammation in the reproductive system and can cause ectopic pregnancies; and trichomoniasis, which can cause vaginitis, urethritis, and cystitis. Many of these infections can be transmitted to babies either during pregnancy or during birth. Some of them may be fatal to the newborn.

Cancer can develop in the female reproductive system. A more common cancer of this type is cervical cancer. Cervical cancer is detected by examination of cells collected from the cervix during a pelvic exam. The microscopic examination of these cells is called a Pap smear.

CONCLUSION: LESSON 6

You’ve finished Lesson 6. There is a required worksheet for Chapters 12-13, which will familiarize you with word parts related to the genitourinary and female reproductive systems. Request it from the professor when you are ready to review. This worksheet must be submitted before you take Quiz 6. When you have finished this worksheet and feel ready, you may take Quiz 6. This is a three-part quiz. The first part is to be taken without using your book or notes. It consists of questions about the concepts in these chapters (Objectives 1-11). Part 2 asks you to define medical terms and write the words for which abbreviations stand (Objectives 12-13). You may not use your book or your glossary for parts 1 and 2. Part 3 asks you to define 25 multi-part medical words (Objective 14). When you have answered all the questions you can without using your glossary, you may take up to 5 minutes to finish, using your glossary. You may NOT use your book.
