Pieces and Parts Heart Lungs Your heart is an organ in your chest, a little to the left of your breastbone. It’s the size of your fist. Your heart pumps your blood through your body. It has 4 chambers that pump the blood. Lungs Your lungs are organs in your chest, inside your rib cage. Your lungs are what make you breathe. They take in oxygen from the air you breathe in (inhale) and release carbon dioxide when you breathe out (exhale). © 2010 Nationwide Children’s Hospital

Pieces and Parts Blood Your blood flows to every part of your body bringing oxygen, and nutrients to your body. Blood is made up of 4 parts: Plasma: the clear part of blood that everything floats around in White blood cells: the cells that fight germs Red blood cells: the cells that bring oxygen to your body and takes carbon dioxide away Platelets: the cells that clot your blood when you get a cut and make a scab © 2010 Nationwide Children’s Hospital

Pieces and Parts Scabs Your scabs are formed by the platelets in your blood. They stick together with fibrinogen and make a web that covers your cut. Scabs protect you from germs that could get in through your cut. Don’t pick your scabs, they are your body’s protection against germs! © 2010 Nationwide Children’s Hospital

Then add a zero to that number and that is how many times your heart beats in one minute. Now, run IN PLACE for one minute. Take your pulse again for 6 seconds and add the zero! (multiply by 10) Did your heart beat faster? Exercise is good for your heart, it makes it stronger! © 2010 Nationwide Children’s Hospital
