Gaseous Exchange Vocabulary Flashcards

Vocabulary flashcards covering key processes, organ requirements, anatomical structures, and mechanisms of gaseous exchange based on the lecture notes.

Cellular respiration

A primary process distinguished from breathing and gas exchange within the topic of gaseous exchange.

Breathing

The mechanical process involving the ventilation of the lungs through inhalation and exhalation.

Gas exchange

The process involving the movement and transport of gases, specifically oxygen and carbon dioxide, across the alveoli and tissues.

Requirements of efficient gas exchange organs

Structural criteria consisting of a large surface area, thinness, moisture, good ventilation, protection, and a transport system.

Trachea

A primary structure of the human ventilation system.

Epiglottis

A functional structure situated within the human ventilation system.

Bronchi

Airway structures forming part of the human ventilation system.

Bronchioles

Subdivided structural passages within the human ventilation system.

Alveolus

The specific site in the ventilation system where gaseous exchange occurs.

Intercostal muscles

Muscles associated with the ribs that form part of the human ventilation system.

Diaphragm

A key muscular structure of the human ventilation system involved in lung ventilation.

Ventilation of the lungs

The physical process of gas movement comprising inhalation and exhalation.

Homeostatic control of breathing

The physiological mechanism responsible for regulating breathing within the body.
