This diagram reflects the laminar flow showing the almost parallel lines of flow that is characteristic of flow in the smaller tubes. Under resting conditions, laminar flow exists from the medium-sized bronchi onward down to the bronchioles. During exercise, the air flow is accelerated, and laminar flow may be confined only to the very small airways.

Parabolic Flow – Highest Velocity in Center and Lowest on the Endothelium
47678d05 aorta blood flow principles velocity parabolic Laminar flow is the normal condition for blood flow throughout most of the circulatory system. characterized by concentric layers of blood move in parallel down the length of a blood vessel. highest velocity (Vmax) isin the center of the vessel. lowest velocity (V=0) is along the vessel wall. T flow profile is parabolic occurs in long, straight blood vessels, under steady flow conditions. Davidoff art Courtesy Ashley Davidoff MD

Turbulent flow
This drawing shows the lines and circles of noisy turbulent flow, which is characteristic of flow in the larger airways.Courtesy of Ashley Davidoff M.D. 42434b07 Histology – Key to Aortic Function is its Elastic Layer (teal)
The Innermost Layer is the Endothelium and Outermost is the Adventitia
