Structure of the Heart 

The heart is a muscular organ located just to the left of the breast bone (sternum). It is about the size of your fist, and this amazing muscle pumps 4300 gallons of blood a day. The heart has four chambers: 

Atria. The top two chambers that receive blood from the body or lungs. 

Ventricles. These are the bottom two chambers of the heart. The right ventricle pumps blood to the lungs to pick up oxygen, The left ventricle pumps blood to the rest of the body and is the strongest chamber. 

Valves. There are four valves in the heart that help to direct blood flow. As they open and close, the valves produce sounds that can be heard with a stethoscope. The heart sounds can often tell your doctor about your heart's function. 

Function of the Heart 

Every cell in your body needs oxygen in order to live and function. The role of the heart is to deliver the oxygen-rich blood to every cell in the body. The arteries are the passageways through which the blood is delivered. The largest artery is the aorta, which branches off the heart and then divides into many smaller arteries. The veins carry the deoxygenated blood back to the lungs to pick up more oxygen, and then back to the heart once again. Blood flows continuously through the circulatory system, and the heart muscle is the pump which makes it all possible!

Suggested Grade Level: 5 ?? 

Science Content Standards: Note the following are examples.

Grade 5: Investigation and Experimentation California Content Standards Life Sciences (2b, e)
2b - Students know how blood circulates through the heart chambers, lungs, and body and how carbon dioxide and oxygen are exchanged in the lungs and tissues.
2e - Students know how sugar, water, and minerals are transported in a vascular plant.

Worksheet, Student made Puzzlemaker Crossword, rubric 


Ex.:  One student at a time can walk through the heart as a blood cell going through the atrium to the ventricle.  Student can then go to the lungs, pick up oxygen (ping pong balls), and carry oxygen out to an arm.  Student drops off oxygen and picks up carbon dioxide(bean bag) and takes it back through the heart to the lungs where it exchanges it for oxygen. Each blood cell needs to collect waste, minerals, carbon dioxide, and oxygen as it wonders through other parts of the body.  The same blood cell drops off these items at the appropriate places in the body.  The cycle repeats itself.  This will reinforce the function of the heart to the human body.
