For the section on the control of adrenaline flow, the first paragraph needs to be rewritten or discarded because your body doesn’t turn on and off; the rate of activities is faster or slower. The second paragraph is much better and more accurate.
I hate this drawing for a number of reasons. It gives no information about what “speeding the liver up” or any other organ you pick means. The kidney on the right side is detached from the bladder. If you look carefully at the kidney, you’ll notice that the adrenal gland is controlled by the sympathetic nervous system on the right and….not controlled by the parasympathetic nervous system on the right. So, according to this Wisdom Booklet, the adrenal gland can be up-regulated, but has NO system of down-regulation. (In real life, the down-regulation is a process of breaking down neurotransmitters and rather complicated.)
