Describe the characteristics of normal urine.
Amount in 24 hours = 1,200–1,500 mL Color, clarity = straw, amber, transparent Odor = faint, aromatic Sterility = no mircroorganisms present pH = 4.5–8 Specific gravity = 1.010–1.025 Glucose = not present Ketone bodies = not present Blood = not present

What are some terms to describe bowel elimination?
Feces
Stool
Defecation
What tends to occur with bowel elimination as we age?
