Period 4
The Urinary System

To remove liquid waste from the blood in the form of urine
Keep a stable balance of salts and other substances in the blood
Function:

Function Continued:
Produce erythropoietin
The kidneys remove urea from the blood

Function Continued:
Maintains normal concentrations of electrolytes within body fluids
Regulates pH and volume of body fluids

1. Filtration
2. Reabsorption
3. Secretion
Urine; a collection of substances that has not been reabsorbed during glomerular filtration or tubular reabsorption
Formation of Urine:

95% water Contains urea and uric acid Amino acids & variety of electrolytes
Reflects on ones dietary intake and physical activity
Composition of Urine:

Urea Source: By-product of amino acid catabolismEnters the renal tubule by filtration
Uric Acid Source: product of the metabolism of certain organic bases in nucleic acidsActive transport reabsorbs all the uric acid
present in glomerular filtrate
Urea & Uric Acid:
