Urinary System Flashcards
(5 cards)
1
Q
If there is increased Hydrogen ions in the blood the blood will be more
A
Acidic
2
Q
How the urinary system regulates pH and electrolytes?
Link to urine formation
A
Kidneys - reabsorb or excrete H+ ions
Electrolytes - salt is reabsorbed/ secreted by kidneys
Both occur during tubular secretion
3
Q
Inputs of water
A
Ingested food
Drinking/ fluids
4
Q
Outputs of water
A
Urine
Sweat
Faeces
Exhaled water vapour
5
Q
Regulating pH
Both in respiratory and urinary systems
A
Hyperventilation removes H+ ions, thereby increasing pH
Hypoventilation increases H+ ions, thereby decreasing pH
Kidneys can excrete bicarbonate ions or retain H+ ions to decrease pH
Kidneys can retain bicarbonate ions or excrete H+ ions to increase pH
