What is the function of the endothelium in relation to the selective permeability barrier?
What is the function of the endothelium in relation to the selective permeability barrier?
- To selectively allow the movement of small and large molecules (correct)
- To only allow the movement of hydrophilic molecules
- To allow all molecules to pass through equally
- To prevent the movement of any molecules
