MASTERBOOKS: Respiratory System Unit 2 Flashcard 2

Front

What are alveoli?

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 primary function of the internal carotid arteries?

Back

The internal carotid arteries provide blood flow to the brain and eyes.

Front

What is gas exchange in the respiratory system?

Back

Gas exchange is the process of transferring oxygen from the air into the blood and removing carbon dioxide from the blood to be exhaled.

Front

What structures are included in the lower respiratory system?

Back

The lower respiratory system includes the trachea, bronchial tree, and lungs.

Front

Which part of the respiratory system is responsible for speech?

Back

The larynx plays a major role in speech production.

Front

What is the role of the nasal conchae?

Back

The nasal conchae are bony structures in the nasal cavity that help to warm and humidify the air as it is inhaled.

Front

What is the function of mucous membranes in the respiratory system?

Back

Mucous membranes line the respiratory tract and help trap dust, pathogens, and other particles, keeping the airways clear.

Front

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

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

How does the diaphragm contribute to breathing?

Back

The diaphragm is a muscle that contracts and relaxes to change the volume of the thoracic cavity, facilitating inhalation and exhalation.

Front

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

Back

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