Answer:

The Respiratory System

When you breathe in, air enters your airways and travels down into the alveoli (air sacs) in your lungs. This is where gas exchange takes place. The circulatory system, which is made up of the heart and blood vessels, supports the respiratory system by bringing blood to and from the lungs.

Answer:

Your lungs are a pair of organs in your chest. They have a spongy texture and are pinkish-gray in color.

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

In addition to the lungs, your respiratory system includes the trachea (windpipe), muscles of the chest wall and diaphragm, blood vessels, and tissues that make breathing and gas exchange possible. Your brain controls your breathing rate (how fast or slow you breathe), by sensing your body’s need for oxygen and its need to get rid of carbon dioxide.

Healthy lifestyle habits, such as physical activity and not smoking, can help prevent lung injury and disease.
