Yes. The top number which is called Systolic is the pressure on the arteries when the heart is contracting. The bottom number which is called Diastolic, is the pressure on the arteries when the heart is relaxed. If you were to feel your pulse, it has a rhythm. When you feel the heart is contracting. The heart is relaxing between the beats.

Do valves inside the veins prevent blood from flowing into the heart?
The blood in veins is not under direct pressure from the heart. It has little valves inside to prevent blood from flowing backwards away from the heart. These valves inside the veins prevent the backflow of blood in veins. They encourage the one-directional flow of blood to the heart.
What prevents the back flow of blood inside heart during contraction?
The valves in the veins
Which artery has the highest blood pressure in body?
The pressure is highest in the arteries and lowest in the veins.
What is miocardia?
Miocardia is the decreasing heart volume during systolic contraction. The rhythmic contraction of the heart, especially the ventricles, via which the blood is returned/ pushed through the aorta and pulmonary artery after each diostole.
Describe how heart contraction and relaxation influence coronary blood flow?
When relaxation or diastole is occurring in the atria blood flows through the atria and the AV valves into the ventricles. When contraction or systole is occurring in the atria the remaining blood that doesn't flow through during relaxation is pushed into the ventricles. As the atria relax, the ventricles begin contracting; ventricular pressure rises, closing the AV valves. Ventricular pressure continues rising until it exceeds the pressure in the large arteries stemming from the ventricles. The SL valves are forced open and blood is expelled from the ventricles into the aorta and pulmonary trunk. During this phase the ventricles relax because the blood is no longer compressed in their chambers. Blood expelled into the aorta and pulmonary trunk backflows toward the heart, which then closes the SL valves. During the ventricle contraction the atria stays in relaxation, filling with blood and when blood pressure on the atrial side of the AV valves exceeds that in the ventricles, the AV valves are forced open and ventricular filling begin all over again.
What is a stolic?
Systolic blood pressure is the measure of the pressure in the heart during a contraction.
When you take someone's blood pressure you are measuring the pressure during the contraction and relaxation phases of the heart muscle?
true
What term is used for Blood pressure during pumping of the heart?
Systole is the term used for contraction, or pumping, of the heart.
When is the Blood pressure greatest in the arteries?
Blood pressure in the arteries is greatest during systole. Systole is the period of heart contraction, while diastole is the period of heart relaxation.
How do blood pressure regulators detect high blood pressure?
Each time the heart contracts a sound is heard, a gauge on the sphygmomanometer measures the pressure that blood exerts during ventricle contraction.
What is the systolic and diastolic?
Systole is the top number of a blood pressure reading. It is the heart contracting forcing blood out. Indicated by the first heart sound. Diastole is the bottom number of a blood pressure reading. It is the heart relaxing bringing blood back in.
What does the systolic readings mean?
The blood pressure when the heart is contracting. It is specifically the maximum arterial pressure during contraction of the left ventricle of the heart. The time at which ventricular contraction occurs is called systole. In a blood pressure reading, the systolic pressure is typically the first number recorded. For example, with a blood pressure of 120/80 ("120 over 80"), the systolic pressure is 120. By "120" is meant 120 mm Hg (millimeters of mercury).
When is blood ejected from the ventricles?
during the systole phase of the heart contraction.
What is the normal blood pressure number for a 50 year old?
he cardiac cycle (heart beat) consists of cardiac muscle contraction (systole) and cardiac muscle relaxation (diastole). Blood pressure represents the force (pressure) exerted by blood against the arterial walls during a cardiac cycle. Systolic blood pressure, the higher of the two pressure measurements, occurs during ventricular contraction (systole) as the heart pumps blood into the aorta. After systole, the ventricles relax (diastole), arterial pressure declines and the heart refills with blood. The lowest pressure reached during ventricular relaxation represents the diastolic blood pressure. Normal systolic blood pressure in an adult varies between 110 and 140 mm Hg, and diastolic pressure varies between 60 and 90 mm Hg.
Why is the blood in an artery flow faster and at a higher pressure than blood in a vein?
It is because your arteries An artery carries blood away from the heart, to the cells of the body. But your veins the vein carries the blood back to the heart
Does the heart receive more arterial blood during ventricular contraction?
yes
Why don arteries pulsate?
They pulsate with each surge of blood from the heart with every contraction as the blood is under high pressure.
