Why doesn’t arterial and venous blood mix in the heart?
| February 11, 2021 | education
The heart of humans and other mammals consists of four chambers. They form the right and left halves of the heart. The blood in the right half is venous; it entered the right atrium, collecting carbon dioxide from the entire body. Then it will go to the right ventricle and from there to the lungs. In the left half, the blood is arterial. It came to the left atrium from the lungs, rich in oxygen. Further, this blood will go to the left ventricle and from there to all organs. In rare cases, there is a defect between the halves of the heart – then the blood mixes. Such a defect is removed by surgery.
