Your bronchi work with your respiratory system to help you breathe. When you breathe: Air passes from your mouth to your trachea. Your trachea divides into your left and right bronchi. The bronchi carry air into your lungs. At the end of the bronchi, the bronchioles carry air to small sacs in your lungs called alveoli.The results shown here suggest that bifurcation should not be the default evolutionary model for time-calibrating trees; however, a budding model also has its limitations. First, the quality of the fossil record varies across the Tree of Life—some major lineages require exceptional preservation to enter the fossil record at all.Aortoiliac occlusive disease (AIOD) is a variant of peripheral artery disease affecting the infrarenal aorta and iliac arteries.

Tree forks are a common feature in trees. They are often responsible for producing some of a crown’s most dominant branches. As branches emerge from a tree fork, they establish a connection to the trunk.

Abstract. In this work we propose an algorithm for computing a stationary flow in a bifurcation tree. Our idea is to divide the tree into smaller basic blocks, each corresponding to one bifurcation, and solve a sequence of flow problems for the individual blocks. Numerical experiments demonstrate that the algorithm works well.

Tree-like branching networks are continuously generated by the main pipe through simple bifurcation rules. The main pipe in the tree-like branching network divides into two or more sub-pipes according to a certain bifurcation angle, and then each sub-pipe divides into a new sub-pipe with the same branch angle.
