Introduction to the Urinary System
The urinary system plays a crucial role in regulating blood volume and pressure, as well as in controlling the concentration of electrolytes and other chemicals in the cells and bloodstream of the body.
The human body absorbs nutrients from food and transforms them into energy. Subsequently, waste products are produced by the body. The kidney and urinary systems assist in eliminating liquid waste known as urea. They also play a role in maintaining a balance of chemicals (like potassium and sodium) and water.
Urea is created during the breakdown of protein-rich foods (e.g. meat, poultry) in the body. It is transported through the blood to the kidneys, where it is excreted, along with water and other waste materials, in the form of urine.
Key term: urea
colorless, odorless solid;
main nitrogen-containing substance in urine
In addition to waste removal, the kidneys help control blood pressure and make the hormone erythropoietin. This hormone controls red blood cell production in the bone marrow. The kidneys also regulate acid-base and fluid balance.
Key term: erythropoietin
glycoprotein hormone manufactured in the peritubular cells of the kidney;
stimulates red blood cell production
Major Functions of the Urinary System
The urinary system filters the blood.
Key functions also include:
Eliminating waste products and medications from the body
Maintain body's fluid balance
Regulate various electrolytes
Secrete hormones to regulate blood pressure
Produce a hormone to regulate the production of red blood cells
Assist in maintaining bone health via the regulation of calcium and phosphorus levels
Major Components Of The Urinary System
Key organs that make up the urinary system include:
The bladder (an organ that holds urine)
Two kidneys (filtering organs)
Two ureters (connect kidneys to the bladder)
The urethra (tube connected to bladder provides pathway for urine to exit body).
