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 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 is noticeable about the muscular walls of the atria and the ventricles?
The walls of the left ventricle are thicker due to having to pump the blood to the body. The walls of the right ventricle are thinner because blood is being pumped into the lungs for gas exchange.
Is the apex of the heart thicker or thinner than the ventricles?
You really can't compare the apex with both because of the apex is made up of only one of the ventricles (the left) and the left is thicker than the right.
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.
What is the Difference between top two heart chambers from the bottom?
The difference between the two sides of the heart starts with their different functions. The larger, more-muscular left side has the job of pumping blood all over the body to take oxygen and nutrients to the body's tissues. The smaller, less-powerful right side is responsible for pumping blood only to the lungs. The blood in the left side of the heart has a higher oxygen content because it has just returned from the lungs. Conversely, the blood in the right side of the heart has a lower oxygen content because it just returned from delivering that oxygen to all the tissues of the body. The body is also known for life and life is very important because of DICKS
Why are the ventricles of a fetal pig thinner than the walls found in the adult pig?
Fetal pigs are not as developed as an adult.
How do the walls of the upper chambers compar to the walls of the lower Chambers?
The walls of the upper chambers are thinner than those of the lower chambers. The upper chambers don't need to generate as much pumping force as the ventricles.
Why do ventricles have thicker muscular valves than atrium?

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.

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 is the difference between an atrium and a ventricle?
Each side of the heart has two compartments or chambers. The top one, called an atrium, collects blood from the veins that are connected to it. Veins are the major blood vessels that deliver blood to the heart. The bottom chamber is larger and is called a ventricle. Ventricles use the squeezing action of powerful muscles to pump blood out of the ventricles and into the arteries connected above them. Arteries are the major blood vessels that take blood away form the heart.The ventricles are more muscular than the atria.The ventricles are larger than the atria.The ventricles have thinner muscle tissue.The ventricles are rougher to the touch than the atria.The ventricles are below the atria.The ventricles pump blood to the body; the atria pump blood to the ventricles.The ventricular walls are thicker than the atrial walls.
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.
When a site other than the SA node becomes the pacemaker that site is called an?
It is called an ectopic pacemaker. It can be located anywhere in the auricles, along the His bundle or in the ventricles (escape beat).
What is noticeable about the muscular walls of the atria and the ventricles?
The walls of the left ventricle are thicker due to having to pump the blood to the body. The walls of the right ventricle are thinner because blood is being pumped into the lungs for gas exchange.

You really can't compare the apex with both because of the apex is made up of only one of the ventricles (the left) and the left is thicker than the right.
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)
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.
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
Are the walls of veins generally much thinner than those of the arteries?
Yes
