What else can I help you with?
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.
What are the walls that divide the heart called?
CHAMBERS?
What are the walls that separates the chambers of the heart?
inter ventricular septum
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.
Name the type of muscle found in the walls of the heart chambers?
Cardiac / Myogenic
What is one of the two thin walls chambers that receive blood into the heart from the veins?
Atrium
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
What part of the heart is described as having thin walls that store blood returning to the heart?
The atria are the chambers of the heart that have thin walls and receive the blood returning to the heart from the body (right atrium) and the lungs (left atrium). They act as collecting chambers and help in pumping blood into the ventricles.
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.
Describe the heart of a frog?
Frogs have hearts that are 3 chambers. The ventricle has a thick wall and the two atria have thin walls.
Why are the walls of the lower chambers of the heart thicker and more muscular than the walls of the upper chambers?
Some terminology first: The upper chambers = atria (singular atrium) The lower chambers = ventricles The atria are responsible for receiving blood: the right atrium receives deoxygenated blood from the body and the left atrium receives oxygenated blood from the lungs. The atria only pump this blood into the ventricles and therefore do not need particularly thick muscular walls. The ventricles on the other hand are responsible for pumping the blood received from the atria to the body. The right ventricle pumps the deoxygenated blood it receives from the right atrium out of the heart and into the lungs. On the other hand, the left ventricle is responsible for pumping the oxygenated blood received by the left atrium to the rest of the body. It is because of the this that the walls on the side of left ventricle are the thickest. The left ventricle requires "more muscle" than the right ventricle as the distance it has to pump the blood is far greater. So, SHORT ANSWER: The walls of the lower chambers/ventricles are thicker and more muscular than the walls of the upper chambers/atria because they have to pump blood out of the heart and to the body as opposed to the atria which only receive blood from the body and then pump into the ventricles.
How do walls of the artia compare with the walls of the ventricles?
Much thinner.
