Answer 1

The Urinary System and Its Major Parts

1. Kidneys- the kidneys are two brownish, bean shaped organs about the size of a fist, they weigh about 5 ounces. They are located in the upper right and left back part of the abdominal cavity. Each kidney contains about 1,200,000 microscopic filters called nephrons. Nephrons are smaller than the smaller dots.

The main function or the kidneys are to maintain the water balance and to eliminate waste materials from the blood.

2. Ureters – the left and the right ureters are long muscular tubes. They are about 12 inches long with a diameter 2 to 3 millimeters.

The ureters connect pelvis of each kidney to urinary bladder. They carry urine from each kidney to the urinary bladder.

3. The Urinary Bladder – the urinary bladder is a muscular sac that holds urine. It is located in front the pelvis and behind the pubis. As the bladder fills walls stretch signaling the desire to urinate.

4. The Urethra- the urethra is a muscular tube which carries urine from the bladder to the outside part of the body. In the female, it is a one inch long from the bladder to the cleft of the labia. In the male, it is several inches long from the prostate gland to the penis. When one is about to urinate, a value in the urethra relaxes to allow the urine to flow out.
