Due to this, there is a greater peripheral resistance because of the small radius and corresponding resistance to the flow of blood.
A healthy individual presumably does not possess an identical accumulation of plaque as the couch potato does. Thus, their blood vessel is larger, resulting in less peripheral resistance and less resistance to the flow of blood.
