This question was attempted by many candidates and their performance was poor. Candidates could not correctly mention factors that help to maintain blood pressure. they muddled their answers by writing immunization from disease, parasite, avoiding things that will bring shock, maintenance of the body posture, reduction of works/abandoning hard work and pulse rate.
The expected answers were as follows:
Factors that maintain blood pressure
- the force of the heart beat
- resistance to blood flow in peripheral arteries/peripheral resistance
- elasticity of arteries
- total amount of circulating blood
- healthy nature of the arteries
- adequate rest, relaxation and sleep
- good nutrition
- regular exercise
