From vena cava to Right atrium
to right ventricle
through pulmonary arteries (deoxygenated blood)
to lungs
back through pulmonary veins (oxygenated blood)
to left atrium
to left ventricle
to aorta (the body)
Veins. The superior and inferior vena cava.
These input blood into the heart chambers.
However if you mean what structures supply blood to the heart itself, this is the job of the coronary arteries. They supply oxygen to the heart muscle.
The right atrium receives deoxygenated blood from the body.
biscupid valve
arteries
Oxygenated blood is pumped out of the heart by the left ventricle.
It comes from the left ventricle out through the aorta.
The left ventricle pumps blood around the body whereas the right ventricle only sends it to the lungs in pulmonary circulation.
The walls of the left atrium contract to force blood through the mitral valve into the left ventricle.
The right ventricle pumps blood to the lungs where the alveoli oxygenate the blood. Then the blood comes back through the pulmonary veins, and into the left atrium, through the valve to the ventricle, to the pulmonary artery, and to the different parts of the body.
The aortic valve is a tricuspid valve that separates the aorta from the left ventricle. The heart pumps blood from the left ventricle, through the aorta, to the body, and the aortic valve prevents the back flow of blood into the left ventricle as the ventricle relaxes and refills with blood from the left atrium.
Oxygenated blood is pumped out of the heart by the left ventricle.
The left ventricle receives blood from the left atrium through the mitral valve.
It comes from the left ventricle out through the aorta.
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.
the left atrium is above the left ventricle. the blood which has been oxygenated from the lungs due to the gas exchange between the alveoli and capillaries comes here from the pulmonary artery this blood then gets sent to the left ventricle through the bicuspid valve this stops the backflow of blood but it allows the blood to go to the left ventricle but does not allow the blood to go back
Blood enters the left ventricle from the left atrium by passing through the mitral valve. The mitral valve functions to prevent blood from flowing back into the left atrium when the left ventricle contracts.
the left atrium is above the left ventricle. the blood which has been oxygenated from the lungs due to the gas exchange between the alveoli and capillaries comes here from the pulmonary artery this blood then gets sent to the left ventricle through the bicuspid valve this stops the backflow of blood but it allows the blood to go to the left ventricle but does not allow the blood to go back
The left ventricle is one of the 4 chambers of the heart
It blocks the backflow of blood from left ventricle to left atrium.
Blood is pumped from the left ventricle through the Aortic Semilunar valve into the Aorta.
The blood then flows into to the right ventricle, and out into the pulmonary artery through the pulmonic valve.
