|<big>The body's source of phosphorus is the diet. What mechanisms enable P absorption across the gut?
||<font color="white"> <big>
*Passive Diffusion
*Vitamin D mediated Active Tranport

|-
|<big>Which hormones affect Phosphorus Homeostasis and how?
||<font color="white"> <big>
*Parathyroid Hormone (PTH)
**Mobilises phosphorus from bone, acting to increase plasma concentration of P
**Increases phosphorus loss in the urine and saliva, acting to decrease plasma concentration
So ultimately, PTH acts to remove phosphorus from the body entirely.
*Calcitriol
**Increases phosphorus absorbtion from the intestines
