Textbook Question

Name the organs of the urinary system, and describe the general function of each organ.

Verified step by step guidance

Identify the organs of the urinary system: kidneys, ureters, urinary bladder, and urethra.

Describe the function of the kidneys: The kidneys filter blood to remove waste products, excess ions, and water, forming urine. They also regulate electrolyte balance, blood pressure, and red blood cell production through hormone secretion.

Explain the function of the ureters: The ureters are muscular tubes that transport urine from the kidneys to the urinary bladder through peristaltic contractions.

Describe the function of the urinary bladder: The urinary bladder is a hollow, muscular organ that stores urine until it is ready to be expelled from the body. It expands as it fills and contracts during urination.

Explain the function of the urethra: The urethra is a tube that carries urine from the urinary bladder to the outside of the body during urination. In males, it also serves as a passageway for semen during reproduction.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Kidneys

The kidneys are two bean-shaped organs that filter blood to remove waste products and excess substances, producing urine. They play a crucial role in regulating electrolyte balance, blood pressure, and acid-base homeostasis. Each kidney contains nephrons, the functional units that perform filtration and reabsorption.

Ureters

Ureters are muscular tubes that transport urine from the kidneys to the bladder. They utilize peristaltic movements to propel urine downward, ensuring a one-way flow. Each ureter is approximately 10-12 inches long and connects to the renal pelvis of the kidney at one end and the bladder at the other.

Bladder

The bladder is a hollow, muscular organ that stores urine until it is ready to be excreted. It can expand and contract, accommodating varying volumes of urine. The bladder's walls contain smooth muscle that facilitates the process of urination through coordinated contractions.
