create a feedback loop

Question

for potassium homeostasis steps, like what happens when potassium levels decrease and how they are brought back to normal??? please keep it simple 

 

Thanks

Answer 1

This is a simplified negative feedback loop related to potassium levels in the body.

Hyperkalemia

Trigger: When you eat a meal that is rich in potassium.

Response: The adrenal cortex of your adrenal glands release the hormone aldosterone. Aldosterone acts on the kidneys to increase the secretion of potassium (K⁺) into the urine. Additionally, skeletal muscle cells take in K⁺.

Result: Blood K⁺ levels decrease back to normal

Hypokalemia

Trigger: Low K+ intake, excessive vomiting, diarrhea, or electrolyte loss

Response: The adrenal cortex of your adrenal glands releases less aldosterone. This decrease in aldosterone causes the kidneys to secrete less K⁺ into the urine and is retained in the blood. Additionally, skeletal muscle cells reduce their uptake of K⁺ and release K⁺ from intracellular stores.

Result: Blood K⁺ rises back to normal
