Lungs

This video tutorial by Matt from Kenhub covers the anatomy of the lungs, including their structure, lobes, fissures, and surfaces. It explains the respiratory pathway from the larynx to the alveoli, detailing the process of gas exchange. The tutorial concludes with a call to explore more resources on Kenhub for further learning.

Which lung is larger and how many lobes does it have?

• The right lung with three lobes

• The right lung with two lobes

• The left lung with three lobes

• The left lung with two lobes

What is the function of the oblique fissure in the lungs?

• To facilitate gas exchange

• To separate the superior and inferior lobes

• To connect the lungs to the heart

• To divide the lungs into costal and mediastinal surfaces

Which surface of the lung is responsible for connecting it to the mediastinum?

• Costal surface

• Mediastinal surface

• Pleural surface

• Diaphragmatic surface

What happens to air after it enters the larynx?

• It moves directly to the alveoli

• It enters the digestive system

• It continues to the trachea and then bifurcates

• It exits the body immediately

Where does the exchange of oxygen and carbon dioxide primarily occur?

• In the larynx

• In the trachea

• In the bronchi

• In the alveoli
