Expected headings
"Urine production"
"Physiological composition"
"The main substances, other than water and simple sugars, include urea (via the breakdown of amino acids), salts (sodium, potassium and chloride), creatinine, ammonia, organic acids, pigments from the degradation of haemoglobin (e.g. urobilin which gives urine its characteristic colour), and hydrophilic toxins."
