What ventricle has the thickest wall and why?

left ventricles . as it pump blood to the aorta it needs a high pressure to take blood all over the body . left ventricle is thick as it needs a high pressure to pump blood and to withstand that pressure.


Why are the walls of the ventricles made of muscle?

The walls of your ventricles are made of smooth muscle because they need to be able to push the blood through your heart. There are valves that open and close to make the blood flow the correct way in the ventricles. The left ventricle has a thicker layer of smooth muscle because it needs to pump blood to the entire body while the right ventricle's smooth muscle doesn't need to be as thick because it is just pumping blood to the lungs which aren't very far away.


What does the atrium and ventricles do?

Right atrium-receives o2 poor blood Left atrium- receives o2- rich blood Right ventricles- sends o2- poor to lung Left ventricle-sends o2- rich blood to body by the way i got all the info from my science teacher


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.


Why do humans have 1 heart but 2 lungs?

Because lungs take in air and air is spread out so it needs more surface area, whereas the heart takes in and pumps blood, which is liquid and needs less surface area. P.S: the heart has two parts, two ventricles and two atria. Don't depend on my ans btw.

Why the atria have less muscular walls than ventricles?

the atria dont have to move blood very far, just to the ventricle directly below them, but the ventricles have to move blood a lot farther, especially the left, since it pushes blood throughout the entire body, so it needs a lot of muscle to do this.

Does the atrium collect blood?

Yes it does collect blood because the blood is meant 4 people who needs it.


Why are atria so thin-walled?

The atria does not need to be very thick because all it needs to do is fill up with blood so that the ventricles can pump out the blood. The ventricular walls are thick so that they can properly pump out blood to the needed areas.


When blood shows anemia is that good?

No, it means that your blood does not contain enough iron (red blood cells) and this needs to be treated.


A condition characterized by the inability of a weak left ventricle to pump enough blood through the body is?

This condition is called heart failure. It occurs when the heart is unable to pump enough blood to meet the body's needs, leading to symptoms like fatigue, shortness of breath, and swelling. Treatment aims to manage symptoms, improve heart function, and address underlying causes.


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.


When the heart is unable to pump enough blood to meet the bodys needs the conditions is known as?

Congestive
