Renal tubules are essential structures in the kidneys. This lesson explores the function of the renal tubule and its parts, including the proximal and distal convoluted tubules, the loop of Henle, and the collecting duct. Learn how these components work together to absorb materials and form urine.elieve it or not, there are about 1,000,000 of these nephrons in each kidney! Regardless, the first section of each individual nephron is called the renal corpuscle and is made up of the glomerulus, which filters the blood, and Bowman's capsule, which collects the ultrafiltrate.
The neck of a guitar showing the nut (in the background, coloured white) and first four metal frets. A fret is a raised element on the neck of a stringed instrument. Frets usually extend across the full width of the neck. On most modern western fretted instruments, frets are metal strips inserted into the fingerboard. On some historical instruments and non-European instruments, frets are made of pieces of string tied around the neck. Frets divide the neck into fixed segments at intervals related to a musical framework. On instruments such as guitars, each fret represents one semitone in the sta

To play the instrument, a musician presses strings down to the fingerboard to change the vibrating length, changing the pitch.
