Heart
i no tink i no
this is the upper part of the heart. there are two of them left aria and right aria (singular)
3 right atrium, left artrium and ventricle
the blood travel through blood vessels is the Artrium or atria. :-)
the right artrium carries deoxygenated blood, while the left atrium carries oxygenated blood
Blood flows from the heart into the left atrium, into the left ventricle. From there, it flows from the right artrium into the left ventricle.
There are two, the Superior Vena Cava that brings blood from the head, and the Inferior Vena Cava that brings blood from the lower body.
sinus Venuses recives De-oxygenated blood fromtwo superior vsna cavae and one inferior vena cava and then pass this blood to right artrium
the tricuspid valve prevents the movement of blood from right ventricle to right atrium the ventricle opens into the aorta though the semi lunar valves
Blood entering the right atrium is deoxygenated and saturated with CO2. Blood that is entering the left atrium has passed through the lungs and is oxygenated. It returns to the left atrium via the pulmonary vein and is saturated with oxygen. - Med Student
