you are mistaken...the ventricular walls are thicker than the auricular walls.. The left ventricle is further thicker than the right ventricle. This is because the left ventricle has to transport blood to all the parts of the body and has to travel a long distance hence requires it to be transported at great pressure. As a result the wall is thicker. The auricles only have to pump blood into the ventricles underneath them and therefore don't require alot of pressure hence are not thick. The right ventricle however pumps the deoxygenated blood into the lungs and has to travel a relatively short distance since the lungs are close to the heart hence not alot of pressure is required either. All this explains why the Ventricular walls are generally thicker than the auricular walls.

Which wave is larger the one for atrial contraction or the one for ventricular contraction?
The wave for ventricular contraction is larger than the wave for atrial contraction. This is because the ventricles have thicker muscle walls and contract more forcefully in order to pump blood out to the body.
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.
How does the structure of a frog's ventricular wall compare to it's atrial wall?
The short Answer: The ventricles have thicker walls than the atrium simply because this is the part of the heart that does most of the pumping action by contracting. It has to be strong and fairly thick to cope with the pressure. (Ventricles have thicker walls than the atrium, which creates a higher blood pressure. The left ventricle has thicker walls because it needs to pump blood to the whole body. The wall of the left ventricle is 8-15 mm The right atrium's wall is approximately 2mm in thickness, due to the combined influence of the low pressure of this chamber and the ease of pumping to low pressure areas)
Is the cell walls of aquatic plants to be thicker or thinner than the cell walls of terrestrial plants?
Aquatic plants have a thicker cell was because they like to defecate on your mom's chest.
Which ventricular wall is thicker what is the significance of this?
The left ventricular wall is typically thicker than the right ventricular wall. This is because the left ventricle needs to generate enough pressure to pump oxygen-rich blood throughout the body, while the right ventricle only needs to pump blood to the lungs. The thicker wall of the left ventricle allows it to generate more forceful contractions to accomplish this.
Is the wall of an artery thicker than that of a vein?
Yes. For equivalently sized arteries and veins, arterial walls are significantly thicker.
Do arteries have the same structure but much thicker walls than veins?
yes
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.
Why are the walls of the ventricle thicker than the walls of the atria?
The ventricles have thicker walls because they need to pump blood out of the heart to the rest of the body, requiring more forceful contractions. In contrast, the atria receive blood from the body and lungs, so they do not need to generate as much pressure and can therefore have thinner walls.
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.
Contrast the structure of veins and arteries for thickness of muscle and elastic tissue?
The more pressure it uses, the thicker the walls will be. Veins have very low pressure which means they have thin walls and vice/versa for arteries which have a higher pressure and thicker walls than veins.
Why are the walls of left ventricles thicker than the walls of right ventricles?
Because the left ventricle pushes blood through most vessels in the body, so it's thicker because more force is needed for the contraction.
