Urinary system
Composition of urinary system ◆ Kidney- to form urine Q Ureter- to conduct urine from kidneys to bladder Bladder-to receive and store urine Q Urethra-to conduct urine from bladder to exterior of body Inferior Aorta vena cava Kidney Bladder Bladder Urethra Rectum
Kidney－ to form urine Ureter － to conduct urine from kidneys to bladder Bladder－to receive and store urine Urethra －to conduct urine from bladder to exterior of body Composition of urinary system
Urinary System Male Female Composition ◆ Kidney- form urine Ureter-conduct urine from kidneys to bladder Bladder-receives and stores urine Urethra-conducts urine from bladder to exterior of body (discharged) Major function ◆ Produce urine Homeostatic function, such as regulation of electrolytes, acid-base balance blood pressure
