How is backflow of blood inside the heart prevented???????? |
|
Answer» Thanks lucifer morningstar☺️☺️ The pulmonary valve sits between the right ventricle and the pulmonary artery. Its role is to prevent the backflow of blood into the right ventricle after it contracts. The aortic valve sits between the left ventricle and the aorta and prevents backflow of blood into the left ventricle after it contracts. |
