Rationale 3: This is a barrier to the distribution of medications.
Rationale 4: There is no blood-lung barrier.

Global Rationale: Three important organs contain anatomic barriers that prevent some drugs from gaining access. These are the brain, the placenta, and the testes. The cellular barriers only allow fat-soluble substances to cross. These are the blood-barrier, blood-placental barrier, and the blood-testicular barrier. There is no blood-lung barrier for the distribution of medication.
