Question

Differentiate between diastole and systole?

Answer 1

Systole is the contraction of the heart muscle. Diastole is the relaxation.

Answer 2

I totally agree with my above colleges.

Answer 3

The heartbeat cycle consists of two components: diastole and systole

    * Diastole occurs when the heart is relaxed and not contracting. During diastole blood fills each of the atria and begins filling the ventricles.

    * Systole occurs when electrical impulse traveling down specialized conducting fibers trigger the heart to contract. The left and right atria contract at nearly the same time pumping remaining blood into the left and right ventricle. Systole continues as the right and left ventricle contract, pumping blood to the lungs and body, several tenths of a second after the right and left atria have contracted.

Systole and diastole continuously alternate as long as the heart continues to beat.
