The left atrium is the chamber that receives oxygenated blood returning from the lungs.
The left atrium receives blood returning to the heart from the lungs.
The left atrium receives blood returning to the heart from the lungs.
To the lungs
The deoxygenated blood goes into the lungs through pulmonary artery from the right ventricle. the oxygenated blood again enters the heart from the lungs by pulmonary veins to the left atrium.
The flow of blood to and from the lungs is called pulmonary circulation.
Approximately 98-99% of the oxygen is retained by the blood returning to the heart when it leaves the lungs under quiet conditions.
It is called the pulmonary circulation, where blood travels to the lungs to receive oxygen and lose carbon dioxide, before returning to the heart.
Oxygenated blood returning from the lungs flow into the left atrium.
Veins are where you will find deoxygenated blood that is returning to the heart to be sent to the lungs.
The right ventricle pumps blood returning from the body to the lungs where it is oxygenated.
The partial pressure of carbon dioxide in the blood returning to the lungs from the body is around 45 mmHg. This is because carbon dioxide is produced as a waste product of cellular respiration in the body's tissues, and it diffuses into the blood to be transported back to the lungs for exhalation.
