What is the connection between heart and lungs?

The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.

Where is the lungs and the heart?

thorax
The heart and lungs are located in the thorax, or chest cavity. The heart pumps blood from the body to the lungs, where the blood is oxygenated. It then returns the blood to the heart, which pumps the freshly oxygenated blood to the rest of the body.

What is the difference between lungs and heart?

The heart is a strong and muscular, cone-shaped organ that is about the size of a fist. It pumps blood throughout the body and is located behind the breastbone between the lungs. Lungs are a pair of highly elastic and spongy organs in the chest. They are the main organs involved in breathing.

How do lungs work?

Once in the lungs, oxygen is moved into the bloodstream and carried through your body. At each cell in your body, oxygen is exchanged for a waste gas called carbon dioxide. Your bloodstream then carries this waste gas back to the lungs where it is removed from the bloodstream and then exhaled.

Can you live on one lung?

Most people can get by with only one lung instead of two, if needed. Usually, one lung can provide enough oxygen and remove enough carbon dioxide, unless the other lung is damaged.

What can you teach children about the lungs?

Classroom Activities for Teaching About the Lungs Explain to your children that their lungs are like balloons. During inhalation, the lungs get filled with air and expand. During exhalation, the lungs contract, or get smaller, and push out carbon dioxide. Have your children blow up balloons to model the lungs.

How do the lungs work step by step?

When you inhale (breathe in), air enters your lungs, and oxygen from that air moves to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathed out). This process, called gas exchange, is essential to life.
