Do arteries have thick walls true or false?
yes, arteries have thick elastic walls which are much thicker than those of a vein.
What are some similarities of the arteries and veins?
Mainly, they're made out of the same tissues in the same order, the difference being how thick those tissues are, a lot thicker in arteries than in veins. They're both responsible for blood flow, being the arteries responsible for blood flow from the heart to the tissues and veins responsible for blood flow from the tissues to the heart.
The arteries of the pulmonary circulation differ from those of the systemic circulation in that they carry?
The arteries of the pulmonary circulation differ from those of the systemic circulation in that they carry?
Do the arteries carry oxgen poor blood or oxygen rich blood?
For the most part arteries carry oxygen-rich blood. Two notable exceptions to this "rule" are the pulmonary arteries and the umbilical arteries. Each of those carry oxygen-poor blood.
What is the difference between an anatomic end artery and a functional end artery?
anatomic end arteries are vessels whose terminal branches donot anastomose with branches of arteries supplying adjacent areas . Functional end arteries are vessels whose terminal branches do anastomose with those of adjacent arteries , but the caliber of anastomoses is insufficient to keep the tissue alive should one of the arteries become occluded .
Why are the walls of the arteries proportionately thicker than those of the corresponding veins?
The walls of the arteries are much thicker than the walls of the corresponding veins. The arteries have thicker walls due to the arteries taking the direct pressure of blood from the pumping heart.
Why are the walls of arteries relatively thicker then those of the corresponding veins?
The walls of arteries are thicker than those of veins so as to keep the pressure of the blood constant while the arteries are constricting or relaxing. Also, the blood pressure in arteries is higher than that in veins, so the walls are thicker to handle the added pressure.
Why are the walls of arteries proportionately thicker than those of the corresponding veins?
In general the walls of arteries are thicker than those of veins. The tunica media in particular tends to be much heavier and contains substantially more smooth muscle and elastic tissue. Arteries are closer to the pumping action of the heart, must be able to expand as an increased volume of blood is propelled into them during systole and then recoiled passively as the blood flows off into the circulation during diastole
Why are the walls of arteries relatively thicker than those of the corresponding veins?
The pressure of the blood flowing through arteries is much higher than veins, so they must be thicker. The arteries are very muscular to maintain good blood pressure.
Why are the walls of arteries proportionately thicker than those of the corrosponding veins?
Artery walls need to be thick because they have to cope with high pressures produced by the cardiac cycle, the arterys are made thick by cardiac muscle.
Why arteries have thicker wall than veins?
The walls of arteries are thicker than those of veins so as to keep the pressure of the blood constant while the arteries are constricting or relaxing
What is the difference between muscle in veins and arteries?
Thee difference between muscle in veins and arteries is that muscles of arteries are thicker compared to those of veins.
Do arteries have thick walls true or false?
yes, arteries have thick elastic walls which are much thicker than those of a vein.
Are walls of veins thicker than the walls of arteries of tthe same size?
walls of veins are always thinner than those of arteries
Why are the walls of arteries proportionately thicker then veins?
In general, the walls of arteries are thicker than those of veins. The tunic media in particular tends to be much heavier and contains substantially more smooth muscle and elastic tissue. This anatomical difference reflects a functional diffeerence in the 2 types of vessels. Arteries, which are closer to the pumping action of the heart, must be able to expand as an increased volume of blood flows off into the circulation during diastole. Their walls much be sufficiently stong and resilient to withstand such pressure fluctuations. The tunica media is thicker in the arteries mainly for maintaing blood pressure and continuous blood circulation.
How thick are the walls of capillaries compared to those of arteries and veins?
Arteries and veins have much thicker walls compared to capillaries. The largest arteries and veins have walls up to 5 mm thick, while capillaries have walls that are only one cell layer thick.
Which blood vessels has the thicker walls?
Arteries are the blood vessels with the thickest walls. The veins have thinner walls, and the walls of capillaries are thinner than those of veins.
