| 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!

 The aorta is curved in shape and elastic in nature while blood is not a simple fluid and hence special circumstances exist |

| 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 |
