How is the structure of arterioles different from that of arteries?
The wall of the arterioles contain less elastic fibers but more smooth muscle cells than that of the aorta and arteries.
Which of the following is a difference between arteries and veins?
artery walls have more elastic tissue and smooth muscle than veins,
Why do arteries have more smooth muscle than veins?
arteries experience higher blood pressure.. apex huh?
Are there more thick filaments than thin filaments in smooth muscle?
There more thin filaments than thick filaments in smooth muscle. The ratio is of the thin to thick filaments in the smooth muscle is approximately 15:1.
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 layer of an artery consists mostly of smooth muscle?
Arterial walls are more muscular than the walls of veins. This muscle is smooth involuntary muscle.
How is smooth muscle significantly different from striated muscle?
Smooth muscle shortens and stretches to a greater extent than does striated muscle.
Where is one smooth muscle cell?
in the heart because smoothe muscle cells have more endurance than other types
What are the predisposing factors to weight loss?
Muscle weighs more than fat, muscle burns fat while you sleep, muscle helps to have healthy circulation, fat clogs the arteries!
Is smooth muscle larger and more powerful than striated muscle?
Both types of muscle come in a variety of sizes. In general the larger muscles are the striated muscles. The power of a muscle is generally proportional to its cross sectional area (bigger is usually more powerful).
Which of the blood vessel has more muscle?
Arteries have more muscular walls than veins and capillaries. This allows the force needed to move blood to the entire body.
Do veins have thick elastic walls?
No, arteries have thicker walls because blood pumps through the arteries around the body, therefore blood pumps through arteries which a high pressure so thick walls are needed. Blood goes through veins with a lower pressure as they lead back to the heart to be oxygenated.
