What stop blood from flowing backwards through the heart? |
|
Answer» A flap like structure called \'Valves\' present in b/w right atrium and right ventricle, b/w right ventricle and pulmonary artery, b/w left atrium and left ventricle and b/w left ventricle and aorta this valves stop blood from flowing backwards through the heart. When the ventricle is full, the tricuspid valve shuts to prevent blood flowing backwards into the atrium. Blood\xa0flows from the right atrium into the right ventricle\xa0through\xa0the tricuspid valve. When the ventricle is full, the tricuspid valve shuts to\xa0prevent blood flowing backwards\xa0into the atrium.\xa0Blood\xa0leaves the\xa0heart through\xa0the pulmonic valve into the pulmonary artery and flows to the lungs.\xa0Blood\xa0enters the\xa0heart through\xa0two large veins, the inferior and superior vena cava, emptying oxygen-poor\xa0blood\xa0from the body into the right atrium of the\xa0heart. As the atrium contracts,\xa0blood flows\xa0from your right atrium into your right ventricle\xa0through\xa0the open tricuspid valve. A sets of valves exist between each atrium and ventricle that prevents the flowing of blood backwards through the heat.?? |
