An adult horse has an average rate of respiration at rest of 12 to 24 breaths per minute. [3] Young foals have higher resting respiratory rates than adult horses, usually 36 to 40 breaths per minute. [3] Heat and humidity can raise the respiration rate considerably, especially if the horse has a dark coat and is in the sun.
The horse's respiratory system consists of the nostrils, pharynx, larynx, trachea, diaphragm, and lungs. Additionally, the nasolacrimal duct and sinuses are connected to the nasal passage. The horse's respiratory system not only allows the animal to breathe, but also is important in the horse's sense of smell (olfactory ability) as well as in ...
Horses are considered obligate nasal breathers. The respiratory system of the horse prevents horses from breathing orally. The epiglottis rests above the soft palate while the animal is not swallowing, forming an airtight seal. Oral breathing can only occur with significant anatomical abnormalities or pathological conditions.
Strangles (also called equine distemper) is a contagious upper respiratory tract infection of horses and other equines caused by a Gram-positive bacterium, Streptococcus equi. [1] As a result, the lymph nodes swell, compressing the pharynx, larynx, and trachea, and can cause airway obstruction leading to death, hence the name strangles. [2]
Approximately 43 to 75% of horses have blood in the trachea and bronchi following a single post-race endoscopic examination. [7] In one study, all horses endoscoped on at least three separate occasions following racing had EIPH at least once. [8] Epistaxis (blood coming from one or both nostrils) is much less common, occurring in 0.25–13% of ...

The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
