When our heart beats it pushes the blood in the arteries and that blood put some pressure on arteries wall called blood pressure. When this pressure increases than the normal blood pressure then it is called higher blood pressure or hypertension.
There can be lots of reasons for high blood pressure like stress, age, genetics and eating disorders. Eating disorders like eating food with high salt and fat content increase the amount of fat in the body. This fat can also accumulate in the walls of arteries which narrow the arteries.
So blood pressure becomes high when blood passes from the narrow arteries causing high blood pressure or hypertension.
A student is trying to reach a goal, that goal is to get good grades. If I wanted to get a phone for working hard in school, it would then be an incentive.
