PRESENTATION OUTLINE
THE PATHWAY OF THE HEART
WHERE IT STARTS AND ENDS
What takes blood to the heart?
The blood goes to the heart in the veins, the blood has no oxygen yet.
Next, before the right ventricle, the blood next travels to the right atrium.
Valves build up pressure to keep the blood flowing in one direction.
Then the right ventricle pumps the blood to the pulmonary arteries.
LUNGS COME NEXT
THE BLOOD FINALLY PICKS UP OXYGEN BY GOING TO THE LUNGS
After getting oxygen the blood flows through the pulmonary veins. This happens before returning to the heart.
The left atrium section is were blood enters the heart from the lungs. Then the left ventricle gets a big pump from the muscles to deliver blood to the rest of the body.
AORTA
- The aorta is the main artery in your body
- It takes your blood from your left ventricle to your arteries
- The artery’s carry the blood to the organs in our body
The small blood vessel that allows the exchange of gases is the capillaries
