Why is the left ventricle of a heart walls the thickest?
=== This is because the left ventricle has more work to do then the right side, so more muscle is needed so the heart will not fail to do its job. (it's job is to pump the blood around to differant parts of the body). EDITED BY JACK NISBET 15
What is the heart part that collects blood from upper part of body?
The part of the heart which collects the blood from the upper part body is the RIGHT ATRIUM. The blood goes from the right atrium in the right ventricle and from the ventricle goes to the lungs where the gases interchange happens. The blood goes than in the Left Atrium through the pulmonary veins, it's pumped in the left ventricle and than it is pumped in the entire body.
Which heart chamber pumps blood throughtout the body?
Though both ventricles of the heart pump blood out of the heart and into the body, I assume you're talking about the chamber that pumps blood to the capillaries of the head and arms or abdominal organs and legs. This would be the left ventricle, which receives oxygenated blood from the left atrium and sends it through the aorta to supply the body's systems with oxygen.
Which layer of the heart enlarges to athletes?
Left ventricle is not a layer, dip head! The appropriate answer would be the myocardium.
What do the left ventricle delivers blood to the?
The entire body. Legs, Head, Arms via the aorta.
Why is the right ventricle not as strong as the left?
The left ventricle pumps blood to the head and the whole body. The right ventricle pumps blood only to the lungs so therefore a smaller workload. The myocardium (heart muscle) is thicker around the left ventricle to give it extra force to pump the blood over longer distances.
The left ventricular wall of the heart is thicker than the right wall in order to?
Pump blood to the entire body. The right ventricular heart only has to pump blood to the lungs, but the left ventricular heart has to pump it from the tops of your brain to the bottom of your toes.

What are nosebleeds a sign of?
In extreme cases, nosebleeds can indicate head trauma. This depends on whether the blood has traces of a runny, pale substance. This is cerebral fluid leaking from the brain.

The entire body. Legs, Head, Arms via the aorta.
What vein carries oxygen rich blood to the heart from the lungs?
The right atrium receives de-oxygenated blood from the body through the superior vena cava (head and upper body) and inferior vena cava (legs and lower torso). The sinoatrial node sends an impulse that causes the cardiac muscle tissue of the atrium to contract in a coordinated, wave-like manner. The tricuspid valve, which separates the right atrium from the right ventricle, opens to allow the de-oxygenated blood collected in the right atrium to flow into the right ventricle. The right ventricle receives de-oxygenated blood as the right atrium contracts. The pulmonary valve leading into the pulmonary artery is closed, allowing the ventricle to fill with blood. Once the ventricles are full, they contract. As the right ventricle contracts, the tricuspid valve closes and the pulmonary valve opens. The closure of the tricuspid valve prevents blood from backing into the right atrium and the opening of the pulmonary valve allows the blood to flow into the pulmonary artery toward the lungs. The left atrium receives oxygenated blood from the lungs through the pulmonary vein. As the contraction triggered by the sinoatrial node progresses through the atria, the blood passes through the mitral valve into the left ventricle. The left ventricle receives oxygenated blood as the left atrium contracts. The blood passes through the mitral valve into the left ventricle. The aortic valve leading into the aorta is closed, allowing the ventricle to fill with blood. Once the ventricles are full, they contract. As the left ventricle contracts, the mitral valve closes and the aortic valve opens. The closure of the mitral valve prevents blood from backing into the left atrium and the opening of the aortic valve allows the blood to flow into the aorta and flow throughout the body.
What- are the parts of the heart and their functions?
Some of the parts of the circulatory system and what they do:* Aorta - the body's largest artery. It takes oxygenated blood from the left ventricle out to the body.* Arteries - carry blood AWAY from the heart* Vena Cava - the largest vein in the body, it carries blood from the body back to the heart (consists of superior and inferior vena cava)* Veins - carry blood TOWARDS the heart* Pulmonary Arteries - carry deoxygenated blood from the right ventricle to the lungs.* Pulmonary Veins - take oxygenated blood from the lungs to the left atrium* Oxygenated blood - blood carrying oxygen after leaving the lungs (blood passes through pulmonary veins back to the heart, enters left atrium, pumped to body by left ventricle)* Deoxygenated blood - blood carrying little oxygen, and carbon dioxide (blood returning the the right atrium, and pumped by the right ventricle through the pulmonary arteries to the lungs)Parts of the Heart* Right Atrium - receives deoxygenated blood from the body, mostly through the inferior and superior vena cava* Right Ventricle - pumps deoxygenated blood into the pulmonary arteries* Left Atrium - receives oxygenated blood from the lungs* Left Ventricle - pumps oxygenated blood into the aorta* Coronary Vessels - supply the heart muscle with its blood supply* Bicuspid Valve - (mitral valve) valve between the left atrium and the left ventricle.* Tricuspid Valve - valve between the right atrium and the right ventricle.----The aorta is the largest single blood vessel in the body. It is approximately the diameter of your thumb. This vessel carries oxygen-rich blood from the left ventricle to the various parts of the body.The superior vena cava is one of the two main veins bringing deoxygenated blood from the body to the heart. Veins from the head and upper body feed into the superior vena cava, which empties into the right atrium of the heart.The inferior vena cava is one of the two main veins bringing de-oxygenated blood from the body to the heart. Veins from the legs and lower torso feed into the inferior vena cava, which empties into the right atrium of the heart.The right atrium receives de-oxygenated blood from the body through the superior vena cava (head and upper body) and inferior vena cava (legs and lower torso).

The closure of the mitral valve prevents blood from backing into the left atrium and the opening of the aortic valve allows the blood to flow into the aorta and flow throughout the body.The pulmonary arteries are the vessels transporting de-oxygenated blood from the right ventricle to the lungs. A common misconception is that all arteries carry oxygen-rich blood. It is more appropriate to classify arteries as vessels carrying blood away from the heart.The pulmonary veins are the vessels transporting oxygen-rich blood from the lungs to the left atrium. A common misconception is that all veins carry de-oxygenated blood. It is more appropriate to classify veins as vessels carrying blood to the heart.The chordae tendineae are string-like in appearance and are sometimes referred to as "heart strings." They connect the heart muscles to the valves.The tricuspid valve separates the right atrium from the right ventricle. It opens to allow the de-oxygenated blood collected in the right atrium to flow into the right ventricle. It closes as the right ventricle contracts, preventing blood from returning to the right atrium; thereby, forcing it to exit through the pulmonary valve into the pulmonary artery.The mitral valve (bicuspid valve) separates the left atrium from the left ventricle. It opens to allow the oxygenated blood collected in the left atrium to flow into the left ventricle. It closes as the left ventricle contracts, preventing blood from returning to the left atrium; thereby, forcing it to exit through the aortic valve into the aorta.The pulmonary valve separates the right ventricle from the pulmonary artery. As the ventricles contract, it opens to allow the de-oxygenated blood collected in the right ventricle to flow to the lungs.

As the ventricles contract, it opens to allow the oxygenated blood collected in the left ventricle to flow throughout the body. It closes as the ventricles relax, preventing blood from returning to the heart.
How blood circulates through the body?
Let's start with deoxygenated blood at the heart. It enters the right atrium of the heart, then passes into the right ventricle. From here, it is pumped to the lungs where gaseous exchange takes place. After this, it returns to heart, the left atrium this time. It passes into the left ventricle and is pumped to all the other organs in the body. The deoxygenated blood returns to the heart to complete the circuit.
Path of blood into the heart?
Deoxygenated blood flows into the right atrium by way of the inferior and superior vena cava. The blood then funnels through the tricuspid valve and builds up in the right ventricle. With a strong contraction upward, the right ventricle pumps the blood upward through the pulmonic valve (pulmonary semilunar valve). The blood moves throught the pulmonary artery to the lungs where the exchange of carbon dioxide for oxygen takes place oxygen takes place. Oxygenated blood then flows from the lungs into the pulmonary veins. The pulmonary vein then dumps the oxygenated blood into the left atrium. Blood funnels through the mitral valve (bicuspid valve) into the left ventricle. a powerful contraction is made to push the blood through the aortic valve Oaortic semilunar valve) into the aorta where the blood is channeled throughout the body.
