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 it called when arteries become thick and lose elasticity?
Over the course of time, the arterial walls are apt to lose elasticity, which limits the amount of blood that can surge through them and hence limits the supply of oxygen to the heart. This condition is known as arteriosclerosis.
What condition causes plaque to accumulate on the walls of the arteries which makes them thicken and lose elasticity?
The condition that causes plaque to accumulate on the walls of the arteries is called atherosclerosis. This process involves the buildup of fatty deposits, cholesterol, and other substances, which leads to inflammation and thickening of the arterial walls, resulting in reduced elasticity. Over time, atherosclerosis can restrict blood flow, increasing the risk of cardiovascular diseases such as heart attacks and strokes. Lifestyle factors like poor diet, lack of exercise, and smoking can contribute to the development of this condition.
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
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.
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 is arteiosclerosis?
a condition when blood vessels lose their elasticity, the blood starts to flow more intermittently rather than a constant flow due to the arteries are unable to expand and relax with the pulse as easily
What causes tortuosity carotid?
Tortuosity of the carotid arteries can be caused by several factors, including aging, atherosclerosis, and genetic predisposition. As individuals age, the arterial walls may lose elasticity, leading to increased bending and twisting. Additionally, atherosclerotic changes can contribute to the structural alterations of the arteries, resulting in tortuosity. Other potential factors include hypertension and lifestyle choices, such as smoking and poor diet, which can exacerbate arterial changes.
What causes plaque to accumulate on the walls of the arteries which makes them thicken and lose elasticity?
Plaque accumulation in the arteries is primarily caused by a combination of high levels of low-density lipoprotein (LDL) cholesterol, hypertension, smoking, and diabetes. These factors lead to endothelial damage, allowing cholesterol, fats, and other substances to infiltrate the arterial walls. Over time, this buildup forms plaques that thicken the artery walls and reduce their elasticity, contributing to atherosclerosis and increasing the risk of cardiovascular diseases. Inflammation and oxidative stress also play crucial roles in the progression of plaque formation.
