What is the flow of blood from heart to the brain?

Answer 1

Pulmonary veins are oxygen rich and deliver it along with nutrients to the body's organs, after the blood has delivered the goods then it is drained back to the heart by the arteries. Then the blood is carried back to the lungs to the alveoli for gas exchange leave carbon dioxide we breathe out and pick up new oxygen and starts over again.

Blood flow goes as follows:

1. left atrium

2. mitral (bicuspid) valve

3. left ventricle

4. aortic semilunar valve

5. aorta

6. brachiocephalic trunk

7. common carotid arteries

8. internal carotid artery

9. anterior and middle cerebral arteries

10. Circle of Willis

11. venous sinuses internal jugular vein

12. right brachiocephalic vein

13. superior vena cava

14. right atrium

15. tricuspid valve

16. right ventricle

17. pulmonary semilunar valve

18. pulmonary trunk

19. pulmonary artery

Answer 2

Blood flows from the pulmonary vein to the pulmonary artery by way of the right side of the brain by flowing through the left atrium, mitral valve, left ventricle, and into the aortic semilunar valve. Next, it goes to the aorta, brachiocephalic trunk, carotid arteries, cerebral arteries, Circle of Willis, jugular vein, brachiocephalic vein, superior vena cava, right atrium, tricuspid valve, right ventricle pulmonary semilunar valve, trunk, and artery.

Answer 3

From the aorta up through either the carotid arteries which supply the greater portion of the brain or the vertebral arteries which supply the poster/inferior portion of the brain.
