Pressure in aorta is greatest during ventricular systole.
True
superior vena cava
An abnormally narrow aorta is a congenital heart defect (called coarctation of the aorta).
Afterload
The right ventricle empties into the pulmonary arteries and the left ventricle empties into the aorta.
"systole"
in the arteries
when it just come out from the heart at the aorta
The pressure is highest in the arteries and lowest in the veins.
arterioles
Blood pressure in the systemic arteries is greatest during systole. Systole is the part of the heart cycle during which the ventricles contract.
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.
Aorta is important in systemic circulation. It is very large vessel. from thorax to lower part of abdomen. It has a cross sectional diameter of about 2.5 cm. So when left ventricle contracts, it gives systemic blood pressure of about 120 mm of mercury. Aorta along with arterial system dilates during systole. Being elastic organ this is possible. Then during diastole, the aorta and aortic system contracts. Thus maintaining the blood pressure, called as diastolic blood pressure. In this it is helped by peripheral resistance of the capillary bed.
