Question

What is the difference between systole and diastole ? Please write three short points

Answer 1

$\huge{\mathcal{\red{\underline{\underline{Answer:-}}}}}$

$\large{\boxed{\boxed{\mathbf{\blue{Systole:-}}}}}$

⭐ Rhythemic contraction of the chambers of the heart.

⭐ It helps in emptying of blood from heart.

⭐ Systole represent the maximum pressure exerted on the arteries.

$\large{\boxed{\boxed{\mathbf{\blue{Diastole:-}}}}}$

⭐ Rhythemic relaxation of the chambers from heart.

⭐ Leads to refilling of heart with blood.

⭐ Diastole represents the minimum pressure exerted in the arteries.

Answer 2

$\bold{\large{\underline{\underline{\sf{ÃnswÊr:}}}}}$

★.Systole is the contraction whereas Diastole is the relaxation of the cardiac cycle.

★.In systole, when the heart contracts the blood pumps from the heart into the aorta and pulmonary artery, but in diastole, when the heart relaxes it allows the heart chambers to be filled with blood from pulmonary veins.

★.The blood pressure of the systole is high and diastole is low.

________________________

Systole:

● The contraction phase of heart is called systole.

●Blood enters arteries due to contraction of atria and ventricles.

●Systole increase pressure in the arterial system.

● The systolic pressure is 120mm of Hg.

Diastole:

● The relaxation phase of heart is called diastole.

●Blood enter into the atria and ventricles due to relaxation.

●Diastole decreases pressure in the arterial system.

●Diastolic pressure is 80mm of Hg.
