An antitussive medication is used to suppress or relieve a cough, targeting the reflex that triggers coughing. The term "antitussive" combines "anti," meaning against, and "tuss," derived from the Latin word for cough, highlighting its purpose in respiratory care.

A collapsed lung, medically referred to as atelectasis, occurs when the alveoli—the tiny air sacs in the lungs—fail to properly expand or dilate. The prefix "atelo-" means incomplete or imperfect, and "ectasis" refers to dilation or expansion. Therefore, atelectasis describes the condition where the alveoli are incompletely expanded, leading to impaired lung function and reduced oxygen exchange.

Suffixes and Prefixes Concept 3 Video Summary

Understanding the respiratory system terminology often involves recognizing key prefixes and suffixes that describe various functions and conditions related to breathing. The suffix -pnea relates to breathing, as seen in terms like sleep apnea, a disorder where breathing repeatedly stops and starts during sleep. Devices such as CPAP machines assist individuals in maintaining proper airflow throughout the night.

The suffix -capnia refers to carbon dioxide levels in the body. For example, hypercapnia indicates elevated carbon dioxide in the bloodstream, which is critical in respiratory physiology and gas exchange processes. Visualizing a "capnia train" emitting carbon dioxide can help remember this association.

-tysis means spitting or expectoration, often used in medical terms describing the expulsion of substances from the respiratory tract, such as in hemoptysis, which is coughing up blood.

The suffix -osmia pertains to the sense of smell, an important sensory function linked to the respiratory system through the nasal passages. Disorders like anosmia involve the loss of smell, affecting respiratory health and quality of life.

Lastly, the prefix syn- means together or with, indicating coordination or union. This can be applied in various biological contexts, such as synchronized actions or processes working collectively.

By integrating these prefixes and suffixes, one can decode and construct complex respiratory system terms, enhancing comprehension of respiratory anatomy, physiology, and related medical conditions.
