arteries
The aortic valve allows the blood to leave the left ventricle.
The heart is divided into four chambers, the right atrium and the right ventricle, and the left atrium and the left ventricle. Blood that is oxygen poor and high in carbon dioxide enters the heart through the right atrium and is then pumped out to go to the lungs via the right ventricle. The left atrium then pumps the newly oxygenated blood into the left ventricle, which then sends the blood to all parts of the body. So, in short, the right ventricle pumps oxygen poor blood to the lungs and the left ventricle pumps oxygen rich blood to the whole body.
Blood passes through the bicuspid valve and enters the left ventricle.
All mammals (monotremes, marsupials, and placental mammals) have the same heart structure: a four chambered heart. The four chambers are the left atrium, the left ventricle, the right atrium, and the right ventricle. The right atrium receives deoxygenated blood from the veins. It pumps it into the right ventricle. The right ventricle pumps it into the pulmonary arteries, which go to the lungs. The lungs have received oxygen and give it to the blood coming through. The now oxygenated blood flows back to the heart by pulmonary veins, and is received by the left atrium. The left atrium pumps the oxygenated blood into the left ventricle. The left ventricle pumps the blood to all of the body through arteries.
After blood leaves the left ventricle, it goes through the aortic valve to be pumped throughout the body.
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 atrium of the heart receives oxygented blood from the pulmonary veins returning oxygenated blood to the heart.
The right ventricle pumps the blood to the lungs.
The right ventricle pumps the blood to the lungs.
The left side of the heart (the left ventricle) pumps blood through aorta into systemic arteries.The right ventricle is the one in charge of pumping the venous blood into the lungs, where blood gets oxygenated and can then go to left ventricle to be pumped through systemic arteries.However, the left ventricle does also pump some blood into the lungs: aorta gives off branches (bronchial arteries) that go into lungs and supply oxygen to the cells of lung tissue.To summarize, lungs get blood from both sides of the heart. From the left ventricle, they get the blood that feeds them, and from the right ventricle they get the blood which they have to fill with oxygen.
right atrium -> right ventricle -> pulmonary artery -> pulmonary vein -> left atrium -> left ventricle -> aorta
it goes into the left atrium in your heart.
