What is the function of the kidneys?
To filter blood and produce urine by removing waste and excess substances.
What are nephrons?
Tiny filtering units in the kidneys that filter blood and form urine.
What does the glomerulus do?
Filters small molecules from blood while keeping larger ones like proteins.
What is the role of the tubule in a nephron?

What do ureters do?
Transport urine from the kidneys to the bladder using peristalsis.
What is the bladder’s function?

Antidiuretic hormone (ADH).
What are kidney stones?
Hard mineral deposits that form in the kidneys and may cause severe pain.
What is acute kidney injury (AKI)?
A sudden loss of kidney function due to factors like dehydration or infection.
What is glomerulonephritis?
Inflammation of glomeruli that affects kidney filtering ability.
What is lupus nephritis?
Kidney inflammation caused by systemic lupus erythematosus.
What is polycystic kidney disease (PKD)?
A genetic disorder where fluid-filled cysts develop in the kidneys.
What causes chronic kidney disease (CKD)?
Long-term damage often due to diabetes or high blood pressure.
What is a urinary tract infection (UTI)?
An infection of the urinary tract usually caused by bacteria like E. coli.
What is urinary incontinence?
The involuntary loss of urine due to various underlying conditions.
What is stress incontinence?
