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.
Smooth muscle fibers in arteries and veins are found in?
tunica media
What does an artery have that a vein does not?
Arteries carry oxygenated blood; veins carry de-oxygenated blood. Arteries have much thicker muscular wall (of muscle and elastic fibres). Arteries have narrow passageway for blood; veins have a wider passageway. Arteries have higher blood pressures. Extra info. if you need it Veins have flaps of valves while arteries do not.
What do arteries and veins drain?
Arteries drain (pump blood) into veins. Veins drain into your lungs and heart to be re-oxygenated. (This is not true for veins and arteries to and from your lungs.)
Do arterioles have valves?
No; arteries (and arterioles) depend on smooth muscle contraction, whereas veins (and venules) have valves.
Are veins and arteries covered by striated muscles?
yes
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.
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.
Name three blood vessels?
the three blood vessels are the Veins capillaries Arteries the arteries.
Which type of muscle constricts veins when blood pressure drops suddenly?
Smooth muscles constrict veins when blood pressure suddenly drops. These types of muscles are the non striated, involuntary muscles found in blood vessels, veins, arteries, the uterus, the bladder, and reproductive tracts.
What type of muscle is found in veins and arteries?
Smooth
What are smooth muscles?
Smooth Muscle contractions are regulated by calcium ions. The smooth muscle differs from skeletal muscle in that its contracts from all sides.
Smooth muscle fibers in arteries and veins are found in?
tunica media
What are the Coronary arteries and veins for?
the coronary arteries feed oxygenated blood to the heart muscle where as the coronary veins take the deoxygenated blood back the heart.
Where are the coronary arteries and veins found?
Coronary arteries and veins are found on the surface of the heart, branching out across the myocardium (muscle tissue of the heart). The coronary arteries supply oxygen-rich blood to the heart muscle, while the coronary veins collect oxygen-depleted blood from the heart muscle and return it to the circulation.
What is the lining of arteries and veins made of that helps them propel blood?
smooth muscle
Are veins under high pressure?
No, veins are not under high pressure. High-pressure vessels are the arteries.
