1 Renal failure may cause pulmonary edema as the kidneys are unable to filter out toxins in the blood. 2  Smoke inhalation may cause severe inflammation of the lung tissue, which results in fluid accumulation in the lungs.  Lymphatic insufficiency result in inadequate drainage of lymph fluid.
Phylogenetic trees are constructed in a variety of ways to summarize the evolutionary relatedness of different organisms. The data represented in a phylogenetic tree may come from (but are not limited to) observations of an organisms anatomical features and/or molecular sequence information.ladistic analysis orders organisms along a phylogenetic tree in branches, and describes the extent of divergence between the branches. If the analysis is based on a molecular sequence alignment, two major computational approaches may be employed in order to construct a tree:
In a rooted phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of the descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. A phylogram is a phylogenetic tree that has branch spans proportional to the amount of character change. 2  A chronogram is a phylogenetic tree that explicitly represents evolutionary time through its branch spans.
