Osmoregulation |
- Filtration - Secretion - Reabsorption |
|
|
Filtration |
At the glomerulus. Filtrate (fluid and small solutes) passes through. Passive Transport. |
|
|
Secretion |
Of acids, bases, and ions from interstitial fluid to filtrate. Maintains pH, [K+] and waste. Passive and Active Transport. |
|
|
Reabsorption |
Essential substances and water flow from filtrate to blood. Enabled by osmolarity gradient and selective permeability of the walls. Passive and Active Transport. |
|
|
Hormonal Regulation |
- Aldosterone - ADH (Vasopressin) - Kidneys |
|
|
Aldosterone |
- Stimulates Na+ reabsorption, K+ and H+ secretion, increasing water reabsorption, blood volume, and blood pressure. - Secreted from adrenal cortex. - Is regulated by the renin-angiotensin-aldosterone system. |
|
|
ADH (Vasopressin) |
Increases collecting duct's permeability to water to increase water reabsorption. - Is secreted from posterior pituitary with high solute in the blood. |
|
|
Kidneys |
Regulate salt and water in the blood. Their functional unit is the nephron. |
