Respiratory System Flashcard

Front

What is the function of the trachea in the respiratory system?

Back

The trachea, or windpipe, directs air into the bronchi, which lead to the lungs.

Front

How does chronic obstructive pulmonary disease (COPD) affect the lungs?

Back

COPD decreases the elasticity of alveoli, reducing the efficiency of gas exchange.

Front

Describe the process of gas exchange in the alveoli.

Back

Oxygen is absorbed into the blood, and carbon dioxide is released from the blood into the alveoli.

Front

What are bronchi and bronchioles?

Back

Bronchi are larger tubes that transport air to the lungs, while bronchioles are smaller tubes that lead to the alveoli.

Front

What is respiration?

Back

Respiration is the process by which organisms use glucose and oxygen to produce energy.

Front

What role do alveoli play in the respiratory system?

Back

Alveoli are tiny air sacs where gas exchange occurs, allowing oxygen to enter the blood and carbon dioxide to be expelled.

Front

What is the primary gas exchanged in the alveoli?

Back

Oxygen is the primary gas absorbed into the blood in the alveoli.

Front

What happens to carbon dioxide during gas exchange?

Back

Carbon dioxide is released from the blood into the alveoli to be exhaled.

Front

How do the bronchi and bronchioles differ in function?

Back

Bronchi transport air to bronchioles, which then transport air to alveoli for gas exchange.

Front

What is the significance of the surface area of alveoli?

Back

A larger surface area of alveoli enhances the efficiency of gas exchange.
