the heart
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 artery that opens to allow oxygen-rich blood to pass from the left ventricle into the aorta is the aortic valve. When the left ventricle contracts, the aortic valve opens, enabling blood to flow into the aorta, which then distributes the oxygenated blood throughout the body.
The bicuspid valve is the valve between the atrium and ventricle on the left side of the heart. It ensures that blood flows in the correct direction - when the ventricle contracts, it prevents the blood from flowing backwards into the atrium.
The right ventricle contracts and pumps the de-saturated blood through the pulmonary valve, and into the lungs via the pulmonary arteries.
the biscuspid valve works as a trap door opening when the oxygented blood needs to pass to the left ventricle
The mitral valve between the left atrium and ventricle.
The deoxygenated blood will enter the heart through the superior and inferior vena cava (the main veins), and will flow into the right atrium. When the right atrium contracts, the blood will go through the tricuspid valve into the right ventricle. When the right ventricle contracts, the blood will go through the pulmonary valve into the pulmonary artery. From there it will go to the lungs where it will undergo an oxygen-carbon dioxide gas exchange in the capillaries surrounding the alveoli. The now oxygenated blood will then leave the lungs and go through the pulmonary vein into the left atrium. It will then go through the mitral valve into the left ventricle. When the left ventricle contracts, it will pass through the aortic valve into the aorta. From the artery it will be distributed throughout the body where it will drop off the oxygen and other substances in various cells. The now deoxygenated blood will return to the heart through the superior and inferior vena cava and start the whole process again. Hope this helps!
In the human heart, each side (left and right) has a valve allowing blood to pass from the atrium into the ventricle, and preventing backflow.The valve between the left atrium and left ventricle is the bicuspid valve (also called mitral valve).The corresponding valve on the right is the tricuspidvalve.
the lower chamber or ventricles of heart receives the blood from respective auricles. From right auricle deoxygented blood flows in right ventricle which is then pass to lungs for purification, and from left auricle oxygenated blood is poured in left ventricle which then provided to different tissue system

Left Auricle and AtriumEach auricle slightly increase the capacity of an atrium so it can hold greater volume of blood.
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)
