Summary
The arterial wall of human medium-sized arteries is essentially incompressible.
The authors of this study investigated whether the arterial wall behaves like incompressible material. They found that the cross-sectional area of the arterial wall of the radial and internal mammary artery remained unchanged under different levels of strain. This suggests that the arterial wall of human medium-sized arteries is essentially incompressible.
This finding is important because it simplifies the analysis of arterial wall elasticity. It also means that the arterial wall can be treated as a rigid tube, which can help develop blood flow.
