- thick cell wall to withstand pressure from the heart
- it has elastic tissue for elastic recoil to take place
and for an extension
- endothelium is folded to expand elastic recoil to let lots of blood through.

∙ 9y agoThe artery has thick walls to allow blood to be pumped at high pressures without bursting the walls. It also has a thick outer layer of collagen to increase its strength. There are many muscle fibres to aid blood pumping. The presence of nuermous elastic fibres enables the artery to be stretched to pump blood after each heartbeat. To help the blood to flow along more quickly, it has a narrow lumen which helps maintain high pressure. It has no valves as the pressure is high enough to prevent the backflow of blood and it has a smooth inner lining to reduce the friction.

What is the function of vertebrarterial canal?
to allow the vertebral artery to pass through to the brain
What is a flow void in a carotid artery?
Mostly because it has no valves, like veins do, so the flow in carotid arteries is a result of left ventricular contraction.Sometimes a flow in the carotid artery is due to a blockage and may be called a 'flow void' and this is a serious condition which can dislodge a thrombosis (Blood clot)and allow it to flow in the cardiovascular system as an embolism, which is a freely moving blood clot. It can get stuck in the lungs (pneumothorax) or in the brain (stroke).
What is the adaptations of an artery?
arteries have thicker walls than veins, as the blood pressure in the artery is more due to the strong heart beat, produced by the aorta.arteries also have elastic layers in them , to withstand the high blood pressure.
Do arteries have valves to allow blood to flow away from the heart?
No, they're aren't any valves in the arteries.
What is the medical term meaning throbbing of an artery?
Arteriorrhexis means rupture of an artery, but it is not commonly used.The term most often used is "ruptured" but these can also be called "dissected" arteries. Dissected usually means that there is leakage of blood inside the layers of arterial tissue. However, if the vessel continues to tear all the way open, it can still be called dissection, but that would most often be called a "ruptured dissection"."Aneurysms" are weakened areas in the walls of arteries that allow them to bulge out or "balloon", these also can rupture and are called a "ruptured aneurysm" or also a "dissected aneurysm" if that happens.Atreriorrhexis means rupture of an artery.Anteri/o mean arteryRrhexis means rupture
What structure does the heart have to allow it to pump efficiently?
Oxygen will keep the heart efficiently pumping so blood can go throughout the body.
What structure must be open to allow blood to flow from the atrium to the ventricle?
the pulmonary artery
How do structures with a cell allow the cell to be specialized?
The structures allow the cell to perform specific functions.
What are the names of the four functions?
they help avoid mistakes they give descriptive information about the species allow organisms to be organized easily and efficiently organisms with similar evolutionary history are classified together
Which type of font will allow you to remember more efficiently?
Arabic
What is the function of vertebrarterial canal?
to allow the vertebral artery to pass through to the brain
Functions of spine?
allow flexibility
What the advantages of having different type of cell?
Cells need to have different sizes and shapes since they all carry out different functions. For example, the nerve cell (neuron) is long and thin to allow the conduction of nerve impulses as efficiently as possible.
What structures must be open to allow blood to flow from the atrium to the ventricle?
the pulmonary artery
What strategies allow us to solve problems and make judgments efficiently are called?
heuristics
What are the different types of car gears?
To allow the engine to operate efficiently will pulling or traveling.
What does a vtec do?
It varies the valve timing on an internal combustion engine to allow it to run more efficiently.
