Nephron: Filtration, Reabsorption and Secretion: a 3D model for Class 10 Biology, covering each kidney contains about a million nephrons, mostly starting in the cortex, filtration: blood pressure pushes water and small solutes from the glomerulus into Bowman's capsule, healthy filtration keeps blood cells and most proteins in the blood; it does not turn blood directly into urine, selective reabsorption returns useful substances (all glucose, most water, many salts) from the tubule to the blood, secretion moves some wastes and ions from the blood into the tubule.

Topics

each kidney contains about a million nephrons, mostly starting in the cortex
filtration: blood pressure pushes water and small solutes from the glomerulus into Bowman's capsule
healthy filtration keeps blood cells and most proteins in the blood; it does not turn blood directly into urine
selective reabsorption returns useful substances (all glucose, most water, many salts) from the tubule to the blood
secretion moves some wastes and ions from the blood into the tubule
reabsorption is tubule to blood and secretion is blood to tubule; neither is the same as excretion
urine is the fluid left in the collecting duct; it drains through the renal pelvis and ureter to the bladder
the bladder stores urine and does not filter blood
blood leaving through the renal vein still has its cells and proteins and carries less waste
