COLLECTING DUCT. It is the final regulator of excretion of many solutes. Its primary function is the transportation of urine and absorption of water. It is the site of action of antidiuretic hormone (ADH).
URETER. It is a muscular tube, composed of an inner longitudinal layer and an outer circular layer of smooth muscle. Its lumen is covered by transitional epithelium. It connects and transports urine from the kidney to the urinary bladder.
LOOP OF HENLE. It is the portion of the nephron that leads from the proximal convoluted tubule to the distal convoluted tubule. It appears to be a hair pin structure that dips down to the medulla. The loop of Henle creates a high osmotic pressure in the renal medulla via the counter-current multiplier system which is essential in reabsorption of water.
