Being muscle, the chambers of the heart may respond to the extra burden of training by becoming hypertrophied, or thicker. This is usually not a problem as long as the cardiac "compliance" (or flexibility) of the chambers is maintained. Age and certain medical conditions, as Diabetes and arteriosclerosis, may cause the chambers to become stiffer.

Which type of vessel carries blood away from the heart?
Arteries carry blood away from the heart and veins carry blood into the heart.
Why do ventricles have thicker muscular valves than atrium?
The walls of the ventricles of the heart aren't thinner than the atria, they are thicker. This is because they require more power as they pump blood around the body, while the atria only pump blood the short distance into the ventricles. More muscular walls are therefore needed to provide this power which is why they are thicker. The left ventricle is even thicker than the right ventricle as it requires a lot more power to pump blood all around the body. The right ventricle only pumps blood to the lungs.
What are the lower two chambers of heart called?
The lower two chambers of the heart are the ventricles. The left ventricle is larger, with thicker walls, than the right ventricle.
Why do auricles have thinner walls than ventricles?
Ventricles have thicker valve thicker wall so that they can withstand the intense pressure by the heart.While auricles carry blood towards the heart and suffers reduced pressure so it has thinner wall
Why are walls of the aorta thicker than walls of the pulmonary artery?
The average pressure pumped through the aorta is about 120mmHg during systole. The average pressure pumped through the pulmonary artery is only 9-18mmHg. The reason for this is simply because of the volume of blood, the resistance to flow by the different pathways they take and so on. But the main point is that to maintain functional integrity and not hypertrophy or cause aneurysm, the aorta must be much thicker with a pressure that great.
Are the walls in arteries thicker than the walls in veins?
The arterial walls are thicker because they need to withstand the pressure coming from the heart.
Why are the walls of the ventricle thicker than the walls of the atria?
The ventricle wall is thicker as it needs to pump blood from the heart to other parts of the body and so it has more pressure than the ventricle walls.
What is the heart's response to dynamic training?
Cardiac enlargement is associated with dynamic training. The heart's response to static training is hypertrophy, thickening of the muscle walls of the heart
Does vena cava or aorta have thicker walls?
The aorta has thicker walls as it is an artery not vein.
Why is the walls of the lower chambers in the heart thicker than the walls of the upper chambers?
Because the net weight of the fluid in the blood is bigger, because the bigger size of the lower chambers (ventricles) allows more blood to accumulate in there, thus causing the need for thicker walls
Why are the walls of arteries relatively thicker than those of the corresponding veins?
In general, the walls of arteries are thicker than those of veins. The tunic media in particular tends to be much heavier and contains substantially more smooth muscle and elastic tissue. This anatomical difference reflects a functional diffeerence in the 2 types of vessels. Arteries, which are closer to the pumping action of the heart, must be able to expand as an increased volume of blood flows off into the circulation during diastole. Their walls much be sufficiently stong and resilient to withstand such pressure fluctuations. The tunica media is thicker in the arteries mainly for maintaing blood pressure and continuous blood circulation.
What part of the frog's heart is thicker?
The wall of the ventricle is thicker than the walls of the atria because the ventricle pumps blood throughout the body, and the wall of the ventricle needs to be thick snd muscular in order to do so.
Why are the artery walls thicker?
to withstand the strong pressure that flows through the vessels as a result of the oxygenated blood that is being pumped from the heart.
Why are arterial walls thicker?
to withstand the strong pressure that flows through the vessels as a result of the oxygenated blood that is being pumped from the heart.
Which walls are thicker those of the atria or those of the ventricle and why?
The ventricle walls are thicker. The blood is being ejected outside of the ventricla
Which chamber of heart is more thicker and why?
The wall of the ventricles is thicker than the walls of the atria as they have to be stronger as they have to pump the blood around the body where as the atria only have to pump blood into the ventricles
Which type of vessel carries blood away from the heart?
Arteries carry blood away from the heart and veins carry blood into the heart.
