Atelectasis is the partial collapse or closure of a lung resulting in reduced or absence in gas exchange. It is usually unilateral, affecting part or all of one lung. [2] It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid.
This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary. There are a few general rules about how they combine.

Cryptorchidism, also known as undescended testis, is the failure of one or both testes to descend into the scrotum. The word is from Ancient Greek κρυπτός (kryptos) ' hidden ' and ὄρχις (orchis) ' testicle ' .

Pronunciation follows convention outside the medical field, in which acronyms are generally pronounced as if they were a word (JAMA, SIDS), initialisms are generally pronounced as individual letters (DNA, SSRI), and abbreviations generally use the expansion (soln. = "solution", sup. = "superior").
Cryptorchidism is associated with tubular atrophy and sterility. In addition, cryptorchid testes carry a three to five times higher risk for testicular cancer (germ cell neoplasia in situ within the atrophic tubules). Patients are at increased risk for the development of cancer and atrophy in the contralateral, normally descended testes as well.
Atelectasis occurs when distending pressure of the alveolus is overcome by surface tension of fluid within the alveolus. Repeated atelectasis and re-inflation leads to atelectotrauma . Atelectotrauma , atelectrauma , cyclic atelectasis or repeated alveolar collapse and expansion ( RACE ) are medical terms for the damage caused to the lung by ...
