Why are the walls of arteries relatively thicker than those of the corresponding 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.
What else can I help you with?
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.
Are the walls in arteries thicker than the walls in veins?
The arterial walls are thicker because they need to withstand the pressure coming from the heart.
What is the thickness of an artery's walls?
It all depends on which one you are comparing, because they come in large ones like the Aorta, down to tiny ones called arterioles. In any case, they are thicker than their corresponding vein.
What blood vessels have thick walls?
Arteries have thick elastic walls that can expand and contract, because they carry blood pumped from the heart. Veins return the blood to the heart but the pressure is not the same as in the arteries.
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.
Which walls are thicker those of the atria or those of the ventricle and why?
The ventricle walls are thicker. The blood is being ejected outside of the ventricla
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?
Why are arteries thicker then 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
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.
Is there any diffference between the bloodpressure in the major arteries of neck and the legs in the space?
Yes, there is a difference in blood pressure between the major arteries of the neck and the legs. Blood pressure is normally higher in the major arteries of the neck (such as the carotid arteries) compared to those in the legs (such as the femoral arteries) due to differences in distance from the heart and the resistance of blood vessels in those areas.
Which peripheral arteries are most commonly treated with peripheral endarterectomy?
The peripheral arteries most often treated with endarterectomy are those that supply the legs, especially the aortoiliac arteries in the pelvic area.
Does the circumflex artery carry oxygen rich or poor blood?
All arteries carry blood that is rich in oxygen except those arteries that carry blood to the lungs called the pulmonary arteries.
