Main Parts of the Urinary System and Their Key Functions

Subject : Biology

Question:

List the parts of the urinary system and describe the function of each one.

Expert Verified Solution:

The urinary system consists of several vital organs and structures that work together to filter and remove waste from the body in the form of urine. The main parts of the urinary system include:

Kidneys:
The kidneys are the primary organs of the urinary system. They filter blood to remove waste products and excess substances, which form urine. They also regulate the body’s balance of water, electrolytes, and pH levels.

Ureters:
The ureters are two thin tubes that transport urine from the kidneys to the bladder. They rely on muscular contractions to move urine downward.

Bladder:
The bladder is a muscular sac that stores urine until it is ready to be excreted from the body. It expands as it fills with urine and contracts when it is time to urinate.

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

Each of these parts plays a crucial role in maintaining the body’s internal environment by filtering blood, removing waste, and regulating fluid balance.
