2.71 describe the structure of a nephron, to include Bowman’s capsule and glomerulus, convoluted tubules, loop of Henlé and collecting duct

Nephrons are tubular structures within the kidneys which carry out filtration.
The blood enters into the glomerulus in the Bowman’s capsule, this is where the blood is filtered to create a filtrate of water, glucose, salts and urea (among other things). This then travels through convoluted tubules, here some components are reabsorbed into the blood stream. The loop of Henlé s where water is where water and sodium chloride and reabsorbed into the blood stream. The filtrate then travels down the collecting duct which transports it to the 'renal pelvis' after which it goes down the ureters to the bladder.
