Overview
This system filters blood and removes wastes like urea
Urinary system
These organs filter blood and remove nitrogenous wastes
Kidneys
This balance prevents dehydration or overhydration
Water balance
This thin tissue allows filtration in nephrons
Simple squamous epithelium
This is the first step where plasma is filtered in the glomerulus
Glomerular filtration
This fluid is produced to carry wastes out of the body
Urine
These tubes transport urine to the bladder using peristalsis
Ureters
These include Na⁺, K⁺, and Ca²⁺
Electrolytes
This tissue reabsorbs nutrients in kidney tubules
Cuboidal epithelium
This process returns water and nutrients to the blood
Tubular reabsorption
This balance keeps the body stable and functioning properly
Homeostasis
This organ stores urine until excretion
Bladder
This balance keeps blood from becoming too acidic
pH balance
This tissue moves urine through ureters and the bladder
Smooth muscle tissue
This process adds wastes like H⁺ and drugs to urine
Tubular secretion
These substances, like sodium and potassium, are regulated by the system
Electrolytes
This structure carries urine out of the body
Urethra
This is controlled by kidney hormones to regulate blood pressure
Blood pressure
This tissue supports kidneys and blood vessels
Connective tissue
These two hormones regulate urine concentration
ADH and aldosterone
This waste forms when the body breaks down proteins
Urea
This type of movement pushes urine through the ureters
Peristalsis
These wastes include urea and creatinine
Metabolic wastes
This tissue stretches as the bladder fills
Transitional epithelium
These are the functional units of the kidneys
Peristalsis
