The word "breaths" is spelled with the combination of two consonants "th" which can be confusing for non-native speakers. The IPA phonetic transcription of "breaths" is /brɛθs/ where the letter "θ" represents the voiceless dental fricative sound that is made by placing the tip of the tongue between the front teeth and blowing air out. The letter "s" at the end indicates plurality. Therefore, "breaths" represents more than one instance of taking air into and out of the lungs.
Breaths are the inhalations and exhalations of air that a person or animal takes in order to sustain life. It is a vital physiological process that involves the intake of oxygen and the release of carbon dioxide. Breathing typically occurs through the nostrils or mouth, with the air passing through the nasal cavity or throat and into the lungs.
During each breath, the body nourishes the bloodstream with oxygen, while simultaneously eliminating waste gases like carbon dioxide through exhalation. This exchange of gases occurs in the alveoli, tiny air sacs at the end of the bronchial tubes in the lungs.
The act of breathing is controlled by the respiratory system, which includes organs such as the lungs, diaphragm, and associated muscles. Normally, breaths are taken unconsciously and automatically to meet the body's oxygen demands. However, breathing can also be controlled voluntarily, allowing for intentional actions such as deep breathing or holding one's breath.
The frequency and depth of breaths can vary greatly depending on factors such as physical activity, stress levels, age, and overall health. An average adult typically takes between 12 to 20 breaths per minute at rest. Disturbances in breathing patterns can be indicative of various medical conditions, such as asthma, chronic obstructive pulmonary disease (COPD), or respiratory infections.
In summary, breaths are the inhalations and exhalations that sustain life, providing the body with vital oxygen and removing waste gases.

The word "breaths" is derived from the Middle English word "breth", which can be traced back to the Old English word "brǣð" or "brǣþ". From there, the word can be further linked to the Proto-Germanic word "brēdiz", meaning "breath" or "vapour". The Proto-Germanic term is believed to have been derived from the Proto-Indo-European root word "bʰrēh₁-" meaning "to breathe" or "to puff". This root word gave rise to several related words in various Indo-European languages, including the Old High German "brādam" and Sanskrit "prāṇá", both meaning "breath".
