What advantage does the chemical compound diffusion method have over electrical impulses in terms of reaching all cells in the body?

The advantage of the chemical compound diffusion method over electrical impulses is its ability to reach all cells in the body, regardless of their location. Chemical signals, such as hormones, can be released into the bloodstream, enabling them to travel to distant target cells throughout the body. This widespread distribution allows for communication with cells in various organs and tissues, including those not directly connected to nerves. In contrast, electrical impulses primarily rely on neural pathways, limiting their reach to areas with a direct nerve connection. Chemical diffusion ensures comprehensive communication and coordination across the entire organism.
