Suppose you recieve a sudden surprize, such as your teacher announcing a surprize test. Your heart may beat faster and your breathing may become irregular. After a short time, your breathing and heart rate return to normal.
a) Which two systems are interacting in this initial reaction?
b) Which system controls and co-ordinates their interaction?
Help with a science question?
a) respiratory (breathing irregular) and circulatory system (heart beat faster - adrenalin)
b) the nerve system (the brain) controls and regulates everything, no mistake with that :)
