HEART AND BLOOD

Page 2: Heart and blood

THE HEART

the heart is an amazing pump that works non-stop, keeping the body alive. With every beat, it sends a surge of bright red blood, carrying vital supplies, such as oxygen, and the body’s waste products such as carbon dioxide, through a network of blood vessels to and from every part of the body. The heart and blood vessels are together known as “circulatory system or cardiovascular system”.

NON STOP PUMP

the heart is a muscular pump that works constantly to squeeze blood into blood vessels called arteries. The arteries take the blood around the body and the veins return the blood to the heart.

THE RIGHT PUMP

the heart is really two pumps side by side. The right blood sends blood along the pulmonary arteries to the lungs where it absorbs oxygen. This blood comes back along the pulmonary veins to the left side of the heart to be pumped around the rest of the body just like a fountain forces water out.

THE LEFT PUMP

the left side of the heart is larger and more powerful than the right side. While the right side of the heart pumps the blood to the lungs the left side pumps blood all around the body, delivers oxygen, energy and nutrients from food to every part. Then the blood which is now low in oxygen, returns from all of these body parts along the veins to heart’s right side. There it begins its non stop journey back to lungs and then around the body once again.
