CLINICAL APPLICATION OF FOUNDATIONAL SCIENCES

The genitourinary system is comprised of the organs and structures involved in reproduction and the formation and excretion of urine. This system performs important functions related to the elimination of the body’s waste products and maintenance of homeostatic environment as well as functions related to reproduction.1 The kidneys are also involved in regulating production of red blood cells, metabolizing hormones, and maintaining the acid–base balance of the blood.2 Furthermore, part of normal kidney function requires unrestricted flow of urine out of the body. Figure 7–1 shows the female and male urinary systems. Table 7–1 shows the common signs and symptoms of urological dysfunction. Table 7–2 summarizes the conditions discussed in this chapter.
