|
|
Mineral function - Iron |
Component of hemoglobin, myoglobin, and cytochromes |
|

|
|
Sodium balance: When sodium gains more than its losses, ECF increases. When it losses more than it gains the ECF decreases. How does this effect osmolarity and ADH secretions |
Increase Na+ levels in ECF = ADH restricts water loss and stimulates thirst promoting water consumption.
Decreased levels of Na+ in ECF = ADH secretion decreases so thirst is suppressed and water losses at the kidneys increase. |
