PRESENTATION OUTLINE
THE PATH OF BLOOD AROUND THE BODY
First, your veins take deoxygenated blood to the heart, where it enters through the right atrium.
Then, it goes to the right ventricle. In between the atrium and ventricle, there are valves that keep blood flowing in one direction.
The right ventricle pumps blood to the pulmonary artery, where it travels to the lungs to pick up oxygen.
After picking up oxygen, blood flows into the pulmonary vein before entering the heart.
Then, it enters through the left atrium. After that, the blood travels to the left ventricle.
The left ventricle pumps blood to the aorta, the main artery in your body, and from there it goes into your arteries to the rest of the body.
Capillaries are small blood vessels that allwas the exchange of gases and is the pathway between veins and arteries.
When organs use up oxygen, they produce a by-product, carbon dioxide.
Finally, the veins take the now deoxygenated blood back to the heart, where the process repeats all over again.
