Traits that are passed down on an X or a Y chromosome are sex-linked traits. Most of the time males are affected by sex-linked traits because males only have one X and a Y. The Y is the chromosome that makes a man, a man.
        
                    
             
        
        
        
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.
