What does systolic and diastolic represent?

What does systolic and diastolic represent?

The first or top number is your systolic blood pressure. This is the amount of pressure in your arteries during the contraction of your heart muscle. The second or bottom number is your diastolic blood pressure. This is the lowest level your blood pressure reaches as your heart relaxes between beats.

What is the function of systole?

systole, period of contraction of the ventricles of the heart that occurs between the first and second heart sounds of the cardiac cycle (the sequence of events in a single heart beat). Systole causes the ejection of blood into the aorta and pulmonary trunk. See also blood pressure.

What does systole and diastole phases mean?

The cardiac cycle is the performance of the human heart from the beginning of one heartbeat to the beginning of the next. It consists of two periods: one during which the heart muscle relaxes and refills with blood, called diastole, following a period of robust contraction and pumping of blood, called systole.

What is systole and diastole quizlet?

Systole is contraction of the muscle while diastole is relaxation of the muscle. The contraction and relaxation of the ventricles are normally described with the term systole and diastole.

What is diastole and systole blood pressure?

Blood pressure is measured using two numbers: The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats. The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.

What is diastole quizlet?

diastole. The stage of the heart cycle in which the heart muscle is relaxed, allowing the chambers to fill with blood. mid-to-late ventricular diastole. Complete relaxation, low pressure, blood flowing passively into ventricles. AV: OPEN SL: CLOSED.

What is diastole in biology?

diastole, in the cardiac cycle, period of relaxation of the heart muscle, accompanied by the filling of the chambers with blood. Diastole is followed in the cardiac cycle by a period of contraction, or systole (q.v.), of the heart muscle.

What is a diastole anatomy?

Diastole is defined by the following characteristics: Diastole is when the heart muscle relaxes. When the heart relaxes, the chambers of the heart fill with blood, and a person’s blood pressure decreases.

What happens in diastole?

Is diastole the same as repolarization?

The same is true of diastole, the relaxation of the heart mucles. Electrical diastole is the recovery and repolarization of the heart in preparation for the next beat.

What does the term systole mean?

Definition of systole. : a rhythmically recurrent contraction especially : the contraction of the heart by which the blood is forced out of the chambers and into the aorta and pulmonary artery — compare diastole.

What does systole and dystole represent?

Systolic and diastolic blood pressures represent the pressures within the blood vessels during different parts of the cardiac cycle . Accurately measuring both of these values is important in diagnosing and managing hypertension.

Is diastole the relaxed phase of the heart?

Diastole is a period when the heart relaxes and expands during refilling the blood which generally occurs after the systole or contraction period. The period during which the two ventricles of the heart are in a relaxed state from the wringing of contraction.
