Difference between Systole and Diastole pressure

The terms systole and diastole refer to two stages of the cardiac cycle . These are cycles that occur when the heart beats to pump blood to the rest of the body. In this article we address all the differences between these two cardiac stages. difference between systole and diastole pressure

This is just one of the main distinctions of these two cardiac phases. If you want to discover them all, keep reading and discover them.

• Systole consists mainly of “pushing” blood out of the heart; while diastole recovers it.
• Systole carries blood to all tissues and organs in the body except the heart and lungs. In contrast, in diastole the latter are nourished by blood supply.
• Diastole is considered “low pressure”, while systole is called “high pressure”.
• Diastole-related conditions are more dangerous than systole, but they all need to be treated.
• In diastole, more use is made of veins than arteries. Instead, systole uses more of the latter for irrigation.

What is Systole? difference between systole and diastole pressure

The part of the cardiac cycle that consists of the expulsion of blood from the heart to the rest of the body is known. And just like a pump, it expels water from one container to another through pipes.

In this way, the arteries efficiently transport blood to the rest of the body’s organs and tissue.

Systole characteristics difference between systole and diastole pressure

The blood is driven by the contraction of the ventricles, it travels through the atria (upper spaces of the heart) and later out through the main arteries.

This is mainly characterized by determining what is popularly known as “high blood pressure” or systolic, which should be within the range of 95-120 mmHg.

It should be mentioned that systole will always be greater than diastole (which we will talk about later) since it drives the blood using the heart muscles.

In addition to the fact that most of the conditions of the human body are related to cardiac tension (systole and diastole), where there is a very strong commercial pharmaceutical component behind.

What is diastole?

It is the phase of the cardiac cycle that includes the “collection” of blood from the tissues and organs to the heart by the veins. It is also known as a “relaxation phase”, because the heart does not contract (in systole it does).

Also in this stage the heart is nourished along with the lungs (something that happens in systole). Being both the heart and the lungs, the only organs that benefit from the blood supply at this stage.

Diastole characteristics

Its main characteristic is its blood pressure level considerably lower than diastole, due to the fact that there is no “pump impulse”, but rather a phase of collecting blood towards the heart again.

It is also important to note that diastole does not use any force to bring blood back to the heart, making it a passive activity.

All this while carbon dioxide is collected from the blood from other organs and tissues to collect it in the lungs, after having passed through the cardiac atria and being expelled during respiration (exhalation).

In this way, diastole works both to irrigate the last organs of the body, and to collect all the waste from it through the bloodstream.
