Chapter 10: Removal of Wastes

Question	Answer
Nephron	Kidneys are composed of large numbers of nephrons
Renal artery	Bring blood to the kidney
Afferent arteriole	Takes blood from renal artery into kidney
Efferent arteriole	Take blood away from the glomerulus, if not filtered
Blood capillary	Surrounds the nephron
Glomerulus	Where glomerular filtration takes place
Bowmans capsule	Surrounds the glomerulus and collects fluid
Proximal convoluted tubule	More filtrate away from bowmans capsule - where reabsorption takes place
Loop of henle	Move filtrate through the nephron - reabsorption continues
Distal convoluted tubule	Continue movement of the filtrate - tubular secretion takes place
Collecting duct	Water absorption
3 major processes of urine formation	1. Glomerular filtration 2. Reabsorption 3. Tubular secretion
1. Glomerular filtration (what occurs)	Substances are forced out at a high pressure from the glomerulus to the bowmans capsule
2. Reabsorption (what occurs)	Blood reabsorbed from filtrate
3. Tubular secretion (what occurs)	Substances move from blood to filtrate
