The term diastole that now concerns us we can establish that it has its etymological origin in Greek. Specifically, it comes from the word “diastole”, which can be translated as “dilation”.
The concept is used to refer to the movement made by the heart when it relaxes so that blood enters its cavity.
It is possible to distinguish between atrial diastole (which allows relaxation of the atria) and ventricular diastole (which relaxes the ventricles). Both make up cardiac diastole, known simply as diastole. See Abbreviation Finder for acronyms related to diastole.
The sequence of activities that allows the heart to pump blood is known as the cardiac cycle. The process begins with systole, which is the contraction of the heart to expel blood. Then, with diastole, blood enters the organ.
It is important to note that blood ejected from the heart in systole does not return to the atria thanks to the closure of the bicuspid and tricuspid valves. This blood passes to the pulmonary arteries, which take it to the lung for oxygenation. The already oxygenated blood, for its part, enters the heart through the left atrium thanks to diastole and, after passing through the left ventricle, it is sent to the rest of the body through the aorta artery.
To all the above it is interesting to add the fact that while in an adult the measurement of the diastolic session is 80 mmHg, millimeters of mercury, in the systolic it is 120 mmHg. In the case of a child, aged between 6 and 9 years, the recommended diastolic pressure is 65 mmHg and systolic is 100 mmHg.
Other differences between diastole and systole are as follows:
Blood pressure is low in diastole and high in systole.
-While in diastole the blood vessels are relaxed, in systole they are contracted.
Diastole is also called a literary figure whose application depends on the characteristics of the language. In Spanish, diastole consists of delaying the accentuation of a syllable passing it to the next, with the intention of achieving a certain rhyme.
A perfect example of diastole is this fragment of a work by the writer Luis de Góngora that says:
“The count, my Lord, is going to Naples
And the Duke, my Lord, goes to France
Majesties, mercy, because this day
I will give sorrow to some snails”.
That without forgetting that we also find it in current songs such as, for example, in the “Rosa de los Vientos” by the Spanish rock band Mago de Oz.
It is also important to know other aspects related to this literary diastole, such as the following:
-It also responds to the name of ecstasy.
-It was used very commonly in Latin.
Diastole, in this context, is part of the set of figures of speech, more precisely the metaplasm (which involves a change in the pronunciation or writing of words without changing their meaning).
