The alveolar surface is a term commonly used in the field of anatomy and physiology. It refers to the surface area of the alveoli, which are tiny air sacs in the lungs responsible for gas exchange. In this article, we will explore the definition, origin, and meaning of alveolar surface, as well as its associations, synonyms, antonyms, and usage in example sentences.
Definitions
The alveolar surface is defined as the total surface area of the alveoli in the lungs. It is a critical factor in determining the efficiency of gas exchange in the lungs, as it provides a large surface area for oxygen and carbon dioxide to diffuse across.
Origin
The term alveolar surface is derived from the Latin word “alveolus,” which means “small cavity” or “little hollow.” The word “surface” refers to the outermost layer of the alveoli, where gas exchange takes place.
Meaning in different dictionaries
According to the Merriam-Webster Dictionary, alveolar surface is defined as “the total area of the alveoli in the lungs, which is the site of gas exchange between the lungs and the blood.” The Oxford English Dictionary defines it as “the surface area of the alveoli in the lungs, where the exchange of oxygen and carbon dioxide takes place.”
Associations
The alveolar surface is closely associated with the respiratory system and is essential for proper lung function. It is also associated with various respiratory diseases, such as emphysema and chronic obstructive pulmonary disease (COPD), which can damage the alveoli and reduce the surface area available for gas exchange.
Synonyms
Synonyms of alveolar surface include alveolar area, pulmonary surface area, and respiratory surface area.
Antonyms
Antonyms of alveolar surface include non-alveolar surface, non-respiratory surface, and non-pulmonary surface.
The same root words
Other words that share the same root as alveolar surface include alveolus, alveoli, and alveolitis.
Example Sentences
- The alveolar surface area is critical for efficient gas exchange in the lungs.
- Smoking can damage the alveoli and reduce the alveolar surface area, leading to respiratory problems.
- The respiratory surface area, including the alveolar surface, is responsible for oxygen uptake and carbon dioxide removal in the lungs.
