10 Crucial Difference Between Systolic and Diastolic Blood Pressures with Table

What is the difference between systolic and diastolic blood pressures?

Research shows that about 40-50% of the total population experience blood pressure issues. It is a serious health problem and it is important to understand blood pressure charts.

But both systolic and diastolic blood pressures are controlled by the heartbeat. The heart contract and relax to enhance the supply of oxygenated blood to the organs, tissues, and cells in the body.

The core difference between systolic and diastolic blood pressure for class 10 is that the former is the pressure generated when the heart muscles contract while the latter is the pressure produced when the heart muscles relax.

Difference Between Systolic and Diastolic Blood Pressures

Comparison Table (Systolic vs Diastolic Blood Pressures)

Basic Terms	Systolic Blood Pressure	Diastolic Blood Pressure
Meaning	It is when the heart muscle contracts or the blood pressure is high	It is when the heart muscles relax or the blood pressure is minimal
Normal Range	Adults: 90 – 120 mmHg Infants: 95 mmHg 6-10 years: 100 mmHg	Adults: 60 – 80 mmHg Infants: 65 mmHg 6-10 years: 65 mmHg
Blood Pressure Inside Arteries	Maximum	Minimum
Occurs	It occurs when the left ventricle of the heart contract	It occurs when the left ventricle of the heart relaxes
Changes with the Age	Increases	Decreases
Blood Pressure Reading	Higher numbers in systolic pressure	Lower numbers in diastolic pressure
Blood Vessels	Contracted	Relaxed
Fluctuations	It happens while an individual is working since the heart is forced to work	It happens when diastolic pressure increases. It is an indicator of heart failure
Etymology	Systolic means drawing together or contracting	Diastolic means drawing apart

What Is a Systolic Blood Pressure?

It is the pressure generated during heart activity to pump blood to different parts of the body through the arteries. Systolic blood pressure happens in two forms.

High systolic blood pressure happens when an individual is exercising at high stress. Low systolic blood pressure occurs when the heartbeat rate is lower than normal.

The dynamics brought about systolic blood pressure can result in different stages of hypertension. It would be best to consider the blood pressure chart to know your level and seek assistance.

What Is a Diastolic Blood Pressure?

It is the pressure generated when the heart is pumping blood inactively to the arteries. It mainly occurs when the heart muscles are relaxed.

The diastole ventricle relaxes and gets filled with blood. Low blood pressure is usually an indicator of heart failure. It would be best to consider seeking immediate medical help.

Main Difference between Systolic and Diastolic Blood Pressure

Blood vessels during systolic blood pressure usually relax while during diastolic blood pressure they contract.
Blood pressure inside arteries during systolic is maximum and minimum during diastolic
Reading of blood pressure during systolic is high and low during diastolic
The ventricle of heart contract during systolic and relax during diastolic
Systolic blood pressure increases with age while diastolic blood pressure decreases with age

Similarities between Systolic and Diastolic Blood Pressure

Both happen in higher organisms
Both occur in the heart
Both are controlled by heartbeat
Both enhance the distribution of oxygenated blood

In Conclusion

The heartbeat causes contraction and relaxation of cardiac muscles. The relaxation and contraction are what result in diastolic and systolic blood pressure respectively.

The health of a person with their cardiac condition is to determine by diastolic and systolic mechanisms. It is advisable to consult your doctor to help in monitoring your heartbeat.
