Trace the path of filtrate and urine from the glomerulus to the external urethral opening

Nephron-- Collecting Tubule-Collecting Duct- Papillary duct- minor Calyx- Major Calyx- Renal Pelvis- Ureters- Bladder- Urethra

Explanation:

Urine is formed in nephron, basic unit of kidneys, through the process of filtration in glomerulus. Nephrons are connected with the collecting duct system of the kidney  to a minor calyx. The collecting duct system consists of  connecting tubule

, medullary collecting duct  and papillary duct. The whole  collecting duct system has a role in reabsorption and excretion.

Papillary ducts open at minor calyx, later in major calyx. Calyces open in pelvis , which is located inside hilum of kidney. Ureters  travel out of kidney through hilum and pour urine into the urinary bladder. Urethra is the outlet that travels from bladder and when the bladder is ful  sphincters control urethral opening to void urine outside the body.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
