Explanation:

1) The dichotomous keys give you information about the groups that are being differentiated to correctly identify them. All you need to do is follow the description of the organisms and the numbers where each description drives you. If you observed correctly the organism, you will reach the scientific name, or genus, or any other taxonomic group you are looking for.

2) Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships. A binomial name is assigned to each organism, composed of a genus and the epithet.  

Among all the categories where organisms are classified, we can find the genus, which includes many species that share some common characteristics that are used to group them together.  

In this example, Alienus is the genus of all these aliens species.

3) Morphological characteristics of aliens are used to identify them and to name them.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
