What is the thick walled blood vessels?
veins
How does the wall of the aorta help to smooth out blood pressure in the aorta?
The wall of the aorta is highly elastic and so distends when the left ventricle contracts pumping blood into it. As the walls close back in they push the blood along in a more smooth fashion. This stops sudden pressure increases from bursting all the vessels.
What is the function of the blood vessels on the outer wall of the heart?
Nutrients and oxygen have to get to the outside of the heart. So the blood vessels on the outside have that job. The nutrients and oxygen can't get to the cardiac muscle from inside the heart. Blood vessels that lead from the heart that are high in oxygen and nutrients have their first branch off the aorta that goes to these blood vessels. That's how important these vessels are to the heart and how it functions.
Why the aorta is the thickest wall vessels in the circulatory system?
aorta has to withstand high blood pressure because of which it needs thick walls !!
Why is the aorta so thick-walled?
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.
Baroreceptors that function in the regulation of blood pressure are located in?
Baroreceptors regulate the blood pressure of all vertebrae and are located in the blood vessels. It is a type of mechanoreceptor which is excited when a blood vessel is stretched.
What transports blood to the vessels of the chest wall?
compare the kinds of blood vessels according to the thickness of the walls
Why is the wall of the aorta thicker than those of the aorta?
You need to read your question and ask it again.
Why is the aortas wall so thick?
The aorta's walls are so thick because it needs to be able to withstand high blood pressure. If they are too thin, the would burst, and your heart would stop pumping blood. A heart without blood is unable to sustain human life.
What are the stuctural difference between aorta and vena cava?
The vena cava has a thinner wall and a wider lumen than the aorta because of the lower blood pressures it has to deal with.
What pumps blood along with digested food?
The blood vessels on the intestinal wall pumps blood along with digested food. They are pumped into the ventral and dorsal blood vessels.
What is an aortic tear?
It is a tear in the wall of the aorta that causes blood to flow between the layers of the wall of the aortaand force the layers apart.
