Trees in Chicago
This is a photo taken near Lake Michigan at the end of the Fall in Chicago showing the illuminated base of the naked trees. The dichotomous branching is reminiscent of the tracheal branching into the two mainstem bronchi. Turn them upside down and the similarity is remarkable. Davidoff photography 22153c02

Aorta and Circulation

The heart and lungs are positioned at the centre of all the organs in the body and they are understandably considered vital organs. Think of yourself as a little red cell within the vast and powerful environment of the circulatory system. Listen and feel the power of the pulse and the rush of all the rivers going back and forth, hither and thither, and around and around – imagine what goes on inside the system all the time – it is probably like walking through a rain forest with huge waterfalls, winding rivers and rivulets – a mixture of gushing power and calm meandering flow- but the colors are reds and blues instead of greens and yellows!

Note the difference in the pressures between the left side of the circulation and the right. The left ventricular pressure reaches a systolic of 120mmHg, while the right atrial pressure is close to zero. This large difference allows blood to flow through the circulation. pressure principles

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
