Term
| Ion Concentration Maintenance |
|
Definition
- Increased ion concentration due to absorption in intestines
- Ion transporters will attempts to absorb excess ions, but needs further removal
- Excess ions remain in the lumen with water, to be excreted through urine |
|
|
Term
| Blood Pressure Regulation |
|
Definition
- Juxtaglomerular apparatus detects high blood pressure, produces enzyme: renin
- Renin converts blood plasma protein angiotensinogen to enzyme angiotensin II
- Angiotensin II initiates vasoconstriction, and releases aldosterone to reabsorb Na+ which increases water intake through osmosis |
|
|
Term
|
Definition
- Too many H+ ions cause the blood pH to lower
- Body regulates pH by expelling CO2 through exhaling
- Also uses bicarbonate buffer system - kidney produces HCO3-, which bonds with H+ to create H2CO3 which disassociates to CO2 and water |
|
|
Term
|
Definition
- Created in the kidneys
- Targets H+ ions in blood to lower pH |
|
|
Term
|
Definition
- Created in juxtaglomerular apparatus
- Converts and creates enzymes to ultimately regular blood pressure |
|
|
Term
| Antidiuretic Hormone (ADH) |
|
Definition
- Created in pituitary gland
- Targets kidneys to signal them to reabsorb more water |
