Christmas trees are everywhere this time of the year! Let’s talk about the anatomical trees of the human body.

The arbor vitae (tree of life) is the white matter in the cerebellum, with a tree-like appearance. The tracheobronchial tree is part of the respiratory system. It is composed of the trachea, the bronchi, and the bronchioles that transport air from the environment to the lungs for gas exchange. While the biliary tree is a group of ducts that collect bile from the hepatic parenchyma and transport it to the duodenum (first part of the small intestine).
