Diastole is the expansion and relaxation of the cardiac muscle. During the relaxation of the heart, the heart's chambers are filled with blood, leading to falling blood pressure.

The cardiac cycle consists of two phases: systole and diastole. These phases can be further divided into atrial systole, ventricular systole, atrial diastole, and ventricular diastole.

Which is Not correctly matched? a. diastole- period when blood is ejected from heart b. pulse- surge of blood that is felt in an artery c. systole- contraction phase of cardiac cycle d. cardiac …

The Cardiac Cycle: The cardiac cycle refers to the sequence of events that the heart goes through as it pumps blood. This cycle can be divided into systole, or contraction, and diastole, or …

During the cardiac cycle, contraction is called systole, and relaxation is called diastole. A cardiac cycle can be divided into two phases: diastole... See full answer below.

2. When is blood forced into the aorta of the human heart? During diastole During systole During both phases of the cardiac cycle During atrial contraction

The opposite of systole is diastole, or the relaxation of the heart during a normal heartbeat. The usual systole definition refers to the contraction of the ventricles.

Answer and Explanation: 1 The correct answer is B. The cardiac cycle refers to the rhythmic relaxation (known as diastole) and contraction (known as systole) of the ventricles....

Atrial systole, atrial diastole, ventricular systole, ventricular diastole, and joint diastole are the events in a cardiac cycle. The average length of a cardiac cycle is 0.8sec.
