Blood pressure varies all the time because of changes in heart beat, which becomes more energetic when it is influenced by adrenaline. Arteries need to have the capacity to expand so that they do not burst, at a time of unusually high blood pressure. So an elastic material is useful, since it has the capacity to stretch without breaking.
What else can I help you with?
Blood flow through the capillaries is steady despite the rhythmic pumping action of the heart because of?
Elasticity of the large arteries.
What is the thickening and loss of elasticity of the arteries referred to as?
atheroma
Which vessels depends on its elasticity ot propel blood along?
Arteries rely on their elasticity to help propel blood along by expanding and contracting with each heartbeat. This elasticity allows arteries to accommodate the surge of blood pumped from the heart and then maintain pressure during diastole.
Which of the vessels depend on its elasticity to propel blood flow?
arteries
Which blood vessels uses elasticity to push blood further along the bloodstream?
michael jackson
Which of these vessels depend s on its elasticity to propel blood along?
Arteries
What causes the arteries to lose there elasticity?
When the artery walls lose their elasticity, this is called arteriosclerosis. When this happens, the body has a tougher time circulating blood.
What is the amount of muscle in veins and arteries?
The amount of muscle in veins and arteries varies in the sense that arteries are more muscular than veins to give them extra elasticity and strength to deal with surges of blood.
What is the effect of the elasticity of the arterie on arterial blood?
The elasticity enables the arteries to change their diameter. Smaller means more pressure, larger means lower pressure.
What is arterial stiffness?
Arterial stiffness is a general term for the elasticity (or compliance) of the arteries. The hardening or stiffening of the arteries is called arteriosclerosis. The stiffness of arteries influences how hard the heart has to work to pump blood through the body.
How the normal elasticity of the large arteries affect both systolic and diastolic pressure?
The normal elasticity of large arteries allows them to expand and accommodate the surge of blood ejected during systole (when the heart contracts), which helps dampen the rise in systolic pressure. This elasticity also aids in maintaining diastolic pressure by recoiling and helping to push blood forward during diastole (when the heart relaxes). As arteries lose elasticity with age or disease, systolic pressure can increase due to higher resistance, while diastolic pressure may decrease, leading to a wider pulse pressure and increased cardiovascular risk.
Why is it an advantage for arteries to have elasticity?
Elasticity allows hormones to travel up AND down the bloodstream easier. (i.e. when the pituitary glands sends GH to the heart and lungs.) without elasticity, we would quickly develop bronchitus after consuming foods or drinks. HOPE THIS HELPS!
