- Viruses have a protein coat
<h3>What are viruses?</h3>
Viruses are microscopic non-cellular structure consisting of a core of DNA or RNA (nucleic acid) surrounded by a protein coat (capsid).
A virus is considered as by non-living because it requires a living host cell to replicate, and often causes disease in the host organism.
Therefore, the characteristics that apply to viruses are;

The highlighted vessels branch into arcuate arteries.
Arcuate arteries- The interlobar arteries bend over to produce imperfect arches at the point where the cortex and medulla meet. The arcuate artery is the name given to this portion of the blood supply as a result. The arcuate artery divides into several tiny radial arteries, which diverge at right angles and provide blood to the cortex.
Vessels- In the blood, vessels (canals) move waste away from organs and tissues and carry nutrients to those tissues. The vasculature's participation in oxygenating the organism serves as one of its main functions and important roles.
