Four pulmonary veins, which are two from each lung, enter the left atrium of the heart. Oxygenated blood is contained in these veins that then drain into the left atrium.

Blood from the lungs enters the heart at what side?
When blood leaves the lungs through the pulmonary veins, it returns to the heart and enters the left ventricle.
Where does the blood enter the heart after it leaves the lungs?
The pulmonary vein enters the left atrium of the heart.
Oxygented blood enters which side of the heart?
Oxygenated blood enters the left side of the heart (atria) via the pulmonary veins
The blood now rich in oxygen re enters the heart though the pulmonary?
When blood that is rich in oxygen re enters the heart, the blood enters through the pulmonary valve. The pulmonary valve brings the oxygen rich blood to the pulmonary trunk of the pulmonary artery.
What are the smallest heart chambers?
The smallest heart chamber is the left atrium. The right atrium is slightly larger than the left.
What are the four chambers on the right and left?
In the heart, there are four chambers. (1) The left atrium, where oxygenated blood enters from the lungs, (2) the left ventricle, where blood flows after the left atrium, (3) the right atrium, where deoxygenated blood returns to the heart via the vena cava, and (4) the right ventricle, where blood is sent back to the lungs via the pulmonary artery.
Where do the blood inflows come from in the heart?
The heart has 4 chambers and blood comes into the heart through 2 of those chambers and exits through the other 2. Oxygen-poor blood enters the heart from the inferior vena cava and superior vena cava, into the right atrium. From there, the blood passes the tricuspid valve and enters the right ventricle. From there, the blood is pumped through the pulmonary valve into the pulmonary arteries and goes to the lungs to dispose of carbon dioxide and collect oxygen. On the left side of the heart, oxygen-rich blood arrives from the lungs via the pulmonary veins where it passes the mitral valve to enter the left ventricle. From there, the blood is pumped through the aortic valve into the aorta.
Where does blood from all parts of the body go in the heart?
Blood returning from systemic circulation enters the heart at the right atrium. Blood from the pulmonary circulation enters the left atrium.
Why are atria called receiving chambers?
They are where the blood enters into the heart, on the right from the the systemic veins, and on the left from the lungs.
Where does oxygenated blood enter the heart?
Through the inferior and superior vena cavaThe left atria of the heart is where oxygenated blood enters, it is then pumped to the left ventricle and then to the rest of the body thru the systematic circuit. The heart is separated by the septum, which separates oxygenated and deoxygenated blood.
Blood returning to the heart from the systemic circuit first enters the?
In the pulmonary circulation, deoxygenated blood leaves the right section of the heart through the pulmonary artery, enters the lungs and oxygenated blood comes through the pulmonary veins. The blood then moves to the left atrium of the heart.
Blood enters the left atrium of the heart from which vessel?
Blood that comes in to the right atrium comes from the pulmonary vein.
