Task 6 of 6 (AC 2.3) Fill in the gaps in the paragraphs below: Blood pressure can be regulated by the nervous system, in particular the ____________________ nervous system. Initially changes to blood composition and pressure can be detected by ____________________: ____________________for pressure, ____________________for chemical changes, ____________________for temperature, and ____________________for movement. These changes are collected by the medulla oblongata in the brain, which will initiate the ____________________nerve to reduce blood pressure or the ____________________system to increase it. So when blood pressure is high, the ____________________system is used, heart rate ____________________and the systolic blood pressure ____________________. When blood pressure is too low, the ____________________system takes over, heart rate and contractility ____________________, and ____________________occurs in the blood vessels.
