The greater the the pulse pressure the lower the pressure gradient driving blood from the aorta through the systemic circulation?
True
Is Blood pressure highest in the aorta and lowest in the capillaries?
superior vena cava
One example of a congenital heart defect is A. leukemia B. chronic high blood pressure C. an abnormally narrow aorta D. anemia?
An abnormally narrow aorta is a congenital heart defect (called coarctation of the aorta).
What is the pressure in the aorta against which the left ventricle must pump blood called?
Afterload
Blood ejected from the ventricles enters which vessels during ventricular systole?
The right ventricle empties into the pulmonary arteries and the left ventricle empties into the aorta.
Pressure in the aorta will be greatest during?
"systole"
Where is blood pressure is the greatest?
in the arteries
When is the blood pressure in systemic arteries greatest?
when it just come out from the heart at the aorta
Which artery has the highest blood pressure in body?
The pressure is highest in the arteries and lowest in the veins.
Where in the circulatory system is blood pressure greatest?
arterioles
When is blood pressure in the systematic arteries the greatest?
Blood pressure in the systemic arteries is greatest during systole. Systole is the part of the heart cycle during which the ventricles contract.
Where is blood pressure the highest?
Aorta
Does the aorta have the lowest blood pressure?
no!
Why does blood pressure in aorta decrease further form heart?
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.
How is the aorta important to the systemic circulation?
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.
The blood pressure in the systemic arteries is greatest during what?
ventricular systole
The pressure difference between the base of the aorta and the right atrium is the?
circulatory pressure
