Your heart pumps blood throughout your whole body. It keeps all the blood in your circulatory system flowing.Your heart first pumps blood to your lungs. Then, the blood picks up oxygen from the air that you have breathed in.The blood (carrying oxygen) then travels back to your heart.he heart gives the blood a second push. This time, it's sent all around the body to the various organs and tissues. And then it all starts again.

# data[].attributes.body
The heart is a muscular organ which pumps blood through the blood vessels of the circulatory system.

# data[].attributes.body
The heart pumps blood with a rhythm determined by a group of pacemaking cells in the sinoatrial node. These generate a current that causes contraction of the heart, traveling through the atrioventricular node . The heart receives blood low in oxygen, which enters the right atrium from the superior and inferior venae cavae and passes to the right ventricle. From here it is pumped into the pulmonary ciruclation, through the lungs where it receives oxygen and gives off carbon dioxide. Oxygenated blood then returns to the left atrium, passes through the left ventricle and is pumped out through the aorta to the systemic circulation−where the oxygen is used and metabolized to carbon dioxide.

# data[].attributes.body
The heart pumps about 100 gallons (380 liters) of blood through your body, every single hour, which is about 2,400 gallons (9000 liters) per day.
