The sequestering results in the organism having a higher concentration of the substance than the concentration in the organism's surrounding environment.

Infectious diseases, also known as transmissible diseases or communicable diseases, comprise clinically evident illness (i.e., characteristic medical signs and/or symptoms of disease) resulting from the infection, presence and growth of pathogenic biological agents in an individual host organism.
a technique used to identify and assess factors that may jeopardize the success of a project or achieving a goal.
