The Left atrium
Gjjjj
oxygenated blood
oxygenated
It is oxygenated as it passes through the lungs. The rest of the body deoxygenates it.
The mitral valve between the left atrium and ventricle.
Oxygenated blood enters the heart in the pulmonary vein. It passes through the left ventricle, before exiting in the aorta.
Your left atrium receive oxygenated blood from the lungs.
it is the atria
the process goes this way. at first all the deoxygenated blood is collected from upper parts of the body through superior venecava and lower parts of the body through the inferior venecava. then it enters the first right chamber of the heart then passes through tricuspid valve to lower right chamber .then it is carried to the lungs through pulmonary artery . there,it gets mixed with oxygen with the help of haemoglobin in the blood. this oxygenated blood gets carried to the left chamber of the heart through pulmonary vein. then it passes through bicuspid valve to the lower left chamber and finally it is pumped out to different parts of the body.
Deoxygenated, it picks up oxygen when it passes the gills.
Left ventricle
Left Ventricle.
the chamber of the heart which receives oxygenated blood from the lungs is the left atrium
