Answer:
Homology refers to the similarities between the group of species that share the common ancestor. The homology individuals arise from a common ancestor. They shows divergent evolution. The basic structure in homology is similar. The organs perform different function. They occur due to the evolutionary process.
Homoplasy refers to the shared characters of the group of species that do not share the common ancestor. The homoplasy do not involve the common ancestor. They shows convergent evolution. The basic structure in homoplasy is different. The organs perform the similar function. They occur due to the adaptation in different habitats.
According to the research, the statement is true. Venous drainage of the head and neck is through the internal jugular vein, which then drain into the brachiocephalic veins.
<h3>What is the internal jugular vein?</h3>
It is a very wide and thick duct that it is responsible for collecting the non-oxygenated blood that comes from the head, from the anterior area of the neck.
Being the largest caliber and the other jugular veins flow into it; it is a continuation of the sigmoid sinus and together with the subclavian vein made up of the brachiocephalic veins that drain blood from the head, neck, and upper extremities.
Therefore, we can conclude that according to the research, the statement is true. Venous drainage of the head and neck is through the internal jugular vein, which then drain into the brachiocephalic veins.
