Answer
This statement is not accurate. The duration of response can vary significantly between these two systems; the nervous system often produces shorter, rapid responses, while the endocrine system can have long-lasting effects.
Step 3
C. use the blood for the transport of their chemical signals.

Answer
This is partially true for the endocrine system, as it uses blood to transport hormones. However, the nervous system primarily uses neurotransmitters across synapses, thus making this statement misleading.
Step 4
D. release chemical signals that act on tissues they control.

Answer
This statement is correct. Both the nervous and endocrine systems release chemical signals (neurotransmitters and hormones respectively) that act on target tissues to regulate various functions in the body.
