How is kidney nephron adapted to its function?

Blood is filtered through the capillaries of the glomerulus into the Bowman's capsule. The Bowman's capsule empties the filtrate into a tubule that is also part of the nephron. The function of the glomerulus is to filter the resultant fluid that will become urine.

Other variations of yellows or red-browns can be more serious. And of course any pain, burning, itching or swelling around the urethra or discharge should be cause for being seen by your family physician.
