The Urinary System Quiz

Urinary System Overview

• The urinary system, also known as the renal system, filters waste and excess fluids from the blood and regulates electrolyte levels.

Components of the Urinary System

• The kidneys filter waste and excess fluids from the blood and regulate electrolyte levels.
• The ureters transport urine from the kidneys to the bladder.
• The bladder stores urine until it is eliminated from the body.
• The urethra is the tube through which urine is eliminated from the body.

Nephrons in the Kidneys

• Nephrons are the functional units of the kidneys that filter waste and excess fluids from the blood.
• Each kidney contains around 1 million nephrons.
• Nephrons contain a glomerulus, a Bowman's capsule, and renal tubules that work together to filter waste and excess fluids from the blood.

Urine Transportation

• Urine is transported from the kidneys to the bladder through the ureters, which are muscular tubes.
• Peristalsis, a wave-like muscle contraction, helps move urine through the ureters.

Differences Between Female and Male Urinary Systems

• The main difference between the female and male urinary systems is the length of the urethra.
• The female urethra is shorter, around 4-5 cm, and opens just above the vagina.
• The male urethra is longer, around 20 cm, and passes through the prostate gland and penis.
