Because pressure is built up in the left ventricle of the heart before it is forced out through the aorta in order for blood to be forced around to the body efficiently to the cells where it is needed. Without this high pressure, blood would not be efficiently ejected to the body and it can pool in the ventricles, which can cause problems.
This high pressure in the ventricle is also required in order for blood to travel around the body. This is because blood moves from an area of high pressure to low pressure to travel. This same principle is used for cells to gain oxygen and other necessities. For example, oxygen will diffuse from the capillaries (smallest blood vessels) which has a high concentration of oxygen into cells, which have a low concentration of oxygen.

When blood leaves the heart and travels through the circulation does the pressure change?
Yes; the blood pressure tends to be highest closest to the heart (actually, the highest pressure in the circulatory system is in the left ventricle) and slowly drops as it reaches the capillaries. However, there is still some blood pressure at the capillaries, which is why the serum can be forced across the capillary wall into the extracellular fluid to exchange nutrients. There is also some blood pressure in the venous system, although it is much lower than the arterial side.
What is heart pressure?
No such thingBlood pressure (BP) is the pressure (force per unit area) exerted by circulating blood on the walls of blood vessels, and constitutes one of the principal vital signs. The pressure of the circulating blood decreases as it moves away from the heart through arteries and capillaries, and toward the heart through veins.
Which type of vessel carries blood away from the heart?
Arteries carry blood away from the heart and veins carry blood into the heart.
Describe the pathway of blood through the heart and lungs relating to pressure and volume?
Describe the pathway of blood through the heart and lungs relating to pressure and volume? Describe the pathway of blood through the heart and lungs relating to pressure and volume?
Which artery has the highest blood pressure in body?
The pressure is highest in the arteries and lowest in the veins.
Where is blood pressure highest in the body?
the blood preasure is highest closest to the heart because that is the organ that pumps all of the blood throughout the body including returning it to the heart
In which type of blood vessel is blood at its highest blood pressure?
Aorta has highest pressure. Pressure gradually decreases as blood moves towards heart.
What is the highest pressure exerted by blood in your arteries called?
The upper Blood Pressure Number is the Systolic, Which is the force of blood in your arteries when you heart beats.
Which blood vessels is blood pressure the highest?
The arteries, which are strong, flexible, and resilient, carry blood away from the heart and bear the highest blood pressures THE AORTA...IT THE FIRST "MAJOR" ARTERY THAT LEAVES THE HEART. 2nd would be the Pulmonary Veins (reversed arteries-veins) in the Respiratory system.
What pressure is exerted when blood is pumped out of the heart?
The pressure generated when blood is pumped out of the heart is called systolic blood pressure. It is the highest pressure in the arteries during the cardiac cycle and represents the force of blood against the arterial walls when the heart contracts.

What is the medical term meaning pressure against the arterial walls when the heart is at rest?
Blood pressure (abbreviated BP) is the pressure of blood against the walls of a vessel. The rhythmic beating nature of that pressure, caused by the alternating ventricular contraction and relaxation in the heart, is the pulse (abbreviated P).Blood pressure has two values - the systolic blood pressure and the diastolic blood pressure.When the heart beats, it pushes blood through the arteries to all of the tissues in the body. It is at this point that the pressure from the blood against the artery walls is at its highest and this value is the systolic blood pressure.When the heart is at rest, in between beats, the pressure on the artery walls is much lower and this value is known as the diastolic blood pressure.blood pressure

Where in the circulatory network is blood pressure highest?
When the heart is in complete relaxation. The pressure in the heart is low, and blood is flowing passively into and through the atria into the ventricles from the pulmonary and systemic circulations. The semilunar valves are closed, and the AV valves are open. Then the atria contract and force the blood remaining in their chambers into the ventricles.
Where in systemic circulation is Blood Pressure highest?
What position is blood pressure normally the highest and lowest?If a person was sitting, reclining, or standing, which position would cause the blood pressure to be highest and lowest?Also, if there was an increase in blood viscosity, cardiac ouput, and diameter of the arterioles would this constitute to an increase in blood pressure as well?blood pressure (BP) is usuall lowest standing position and highest in supine (reclining) position. This is because the blood return to the heart is decreased when standing.http://www.bloodpressureinc.com/what-position-is-blood-pressure-normally-the-highest-and-lowest/Exercise is at its highest when we exercise and lowest when we sleep.
What type of blood vessel is blood pressure highest in?
Blood pressure is highest in arteries, specifically in the large arteries like the aorta, as they receive blood from the heart during systole and distribute it throughout the body. This high pressure enables the blood to reach all tissues and organs efficiently.
