Respiratory System Practical

Front

What is the function of the Nasopharynx?

Back

The Nasopharynx serves as a passage for air from the nasal cavity to the oropharynx and contains the adenoids, which help in immune response.

Front

What is the role of the Nostril in the respiratory system?

Back

Nostrils are the external openings of the nasal cavity that allow air to enter and exit the respiratory system.

Front

What are the lobes of the lungs?

Back

The lungs are divided into lobes: the right lung has three lobes (superior, middle, inferior) and the left lung has two lobes (superior, inferior).

Front

What is the function of the Tertiary Bronchus?

Back

The Tertiary Bronchus branches from the secondary bronchus and conducts air to specific segments of the lungs.

Front

What is the significance of the Left Bronchus?

Back

The Left Bronchus is the airway that leads to the left lung and is typically longer and more horizontal than the right bronchus.

Front

Define the Trachea.

Back

The Trachea, or windpipe, is a tube that connects the larynx to the bronchi, allowing air to pass to and from the lungs.

Front

What is the role of the Alveoli in the respiratory system?

Back

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

Front

What is the function of the Diaphragm?

Back

The Diaphragm is a muscle that separates the thoracic cavity from the abdominal cavity and plays a crucial role in breathing by contracting and relaxing.

Front

What is the difference between the Primary Bronchus and Secondary Bronchus?

Back

The Primary Bronchus is the main airway that branches from the trachea into each lung, while the Secondary Bronchus branches from the primary bronchus and leads to the lobes of the lungs.

Front

What is the purpose of the Larynx?

Back

The Larynx, or voice box, is responsible for sound production and protects the trachea against food aspiration.
