Front

What is the primary function of the alveoli in the lungs?

Back

The alveoli are tiny air sacs where the exchange of oxygen and carbon dioxide occurs between the air and the blood in the capillaries.

Front

How does the body release carbon dioxide?

Back

Carbon dioxide is released from the body when we exhale.

Front

What gases are exchanged during respiration?

Back

During respiration, oxygen is taken in and carbon dioxide is removed.

Front

What bodily functions are affected by the respiratory system?

Back

Functions such as yawning, hiccups, and sneezing are all affected by the respiratory system.

Front

Which of the following is NOT part of the respiratory system: nose, trachea, lungs, alveoli, or tongue, esophagus, stomach?

Front

What role does the diaphragm play in breathing?

Back

The diaphragm is a muscle that contracts and relaxes to help draw air into the lungs and push it out.

Front

What is the trachea's function in the respiratory system?

Back

The trachea, or windpipe, serves as the main airway that connects the throat to the lungs, allowing air to pass through.

Front

Explain the process of gas exchange in the alveoli.

Back

Gas exchange in the alveoli occurs when oxygen from the air diffuses into the blood, and carbon dioxide from the blood diffuses into the air to be exhaled.

Front

What is the significance of the bronchi in the respiratory system?

Back

The bronchi are the main passageways that branch from the trachea into each lung, directing air to the alveoli.
