The heart is a muscular organ responsible for pumping blood throughout the body. It ensures that oxygen and nutrients are delivered to all tissues and organs, while also removing waste products.
The lungs are responsible for gas exchange – taking in oxygen from the air we breathe and releasing carbon dioxide from the blood. They work closely with the heart to oxygenate the blood that is then circulated throughout the body.
| Feature | Heart | Lungs |
|---|---|---|
| Primary Function | Pumping blood | Gas exchange (oxygen in, carbon dioxide out) |
| Location | Thoracic cavity, between the lungs | Thoracic cavity, flanking the heart |
| Main Vessels | Aorta, pulmonary artery, vena cava, pulmonary veins | Pulmonary artery, pulmonary veins, bronchioles |
| Chambers/Lobes | Four chambers (two atria, two ventricles) | Lobes (two in left lung, three in right lung) |
| Blood Type | Both oxygenated and deoxygenated blood flow through the heart. | Oxygenated blood exits the lungs; deoxygenated blood enters the lungs. |
