Your answer is incorrect. Organs or tissues differ in the amount of a chemical that they receive or to which they are exposed. This is primarily due to two factors, the volume of blood flowing through a specific tissue and the presence of special "barriers" to slow down toxicant entrance. Organs that receive larger blood volumes can potentially accumulate more of a given toxicant. A toxicant will move from the heart to all areas of the body in less than a minute. It is rare that an absorbed toxicant is so unstable as to disintegrate quick enough to affect the relative concentrations in various organs.
