| Front | Stages for reabsorption of glucose and amino acids |
|---|---|
| Back | Sodium potassium pump actively transports sodium ions from cells lining the PCT into capillaries This lowers sodium ion concentration in cells lining the PCT Sodium ions facilitated diffused into cells lining the PCT from the fluid in the PCT Facilitated diffusion involves Co-transport of sodium ions with another molecule from the fluid in the PCT(Chlorine of Vitamins) depending on the carrier molecule The carrier molecule diffuses into the capillaries Reabsorption of sodium ions, amino acids and glucose from the fluid in the PCT increases the water potential of the fluid Water enters the PCT cells from the tubule fluid and is reabsorbed into the blood by osmosis |
