The minimum pressure in the aorta, known as diastolic pressure, occurs when the heart is relaxed and typically ranges from about 60 to 80 mmHg. The maximum pressure, or systolic pressure, occurs when the heart contracts to pump blood and usually ranges from 90 to 120 mmHg. The difference between these two pressures is termed the pulse pressure, which generally ranges from 40 to 50 mmHg in healthy individuals. This difference reflects the force of each heartbeat and the elasticity of the arterial walls.
The difference between the maximum and minimum pressure in the aorta is known as the pulse pressure. During the cardiac cycle, systolic pressure (maximum) occurs when the heart contracts and pumps blood into the aorta, while diastolic pressure (minimum) occurs when the heart is at rest between beats. Normally, the pulse pressure in a healthy adult is about 40 mmHg, representing the force that drives blood through the circulatory system. This difference can vary based on factors like age, health, and physical condition.
Aorta is not math its science, Aorta is the largest artery in the human body.
Ascending simply means that "x" originates at a lower point than it terminates. For example, the ascending aorta starts from the left ventricle and ends at the arch of the aorta. The left ventricle is inferior to the arch of the aorta, thus that portion of the aorta is considered ascending.
Left-sided afterload is primarily measured using the systemic vascular resistance (SVR), which reflects the resistance the left ventricle must overcome to eject blood into the aorta. This can be calculated using the formula: SVR = (MAP - CVP) / CO, where MAP is the mean arterial pressure, CVP is the central venous pressure, and CO is the cardiac output. Additionally, techniques like echocardiography can assess left ventricular wall stress and other parameters related to afterload indirectly.
Tetralogy of Fallot is characterized by four congenital heart defects: 1) ventricular septal defect (a hole between the lower chambers of the heart), 2) pulmonary stenosis (narrowing of the outflow tract from the right ventricle to the pulmonary artery), 3) right ventricular hypertrophy (thickening of the right ventricle muscle), and 4) overriding aorta (the aorta is positioned directly over the ventricular septal defect, instead of arising solely from the left ventricle). These conditions lead to reduced oxygenated blood flow to the body, causing cyanosis and other complications.

circulatory pressure
The pressure in the aorta is greatest during ventricular systole, which is when the heart contracts and pumps blood into the aorta. This creates a surge in pressure that is known as systolic blood pressure.
the difference between aortic diastolic and right atrial diastolic pressure; a determinant of the blood flow to cardiac muscle.
Aorta
no!
As the blood moves through the aorta, the friction of the walls of the aorta decreases velocity. This velocity decrease results in a decrease in pressure.
"systole"
Pressure must move from one area to another, otherwise no flow will occur. In the case of the human heart, pressure pushes blood from the aorta, through arteries, arterioles, capillaries, venuoles, and finally veins, to the vena cavae, where the blood goes back into the heart to be re-oxygenated.
this is because, due to high thickness of left ventricle blood gets into the aorta with high pressure, and if the aortic wall is not thick, high blood pressure in aorta breaks open wall.
Blood is under the most pressure in the aorta- the largest artery in the body originating fro the left ventricle of the heart.
