Shock (circulatory) Shock is the state of not enough blood flow to the tissues of the body as a result of problems with the circulatory system.
The circulatory system is similar to a road & highway system because the circulatory system is a way for nutrients and other stuff to flow through to your muscles, brain and organs (The nutrients and stuff are like cars). The blood veins, and vessels are like the roads that direct the stuff to the places they need to be.
It is carried in the form of a gene.
Because most but not all 13 yrs olds and older smoke already and they just want to know if you have already smoked before
