A CT scan showing evidence of the nasal cycle: the more patent airway is on the right of the image, the swollen turbinates congesting the left. The nasal cycle is the subconscious [1] [2] alternating partial congestion and decongestion of the nasal cavities in humans and other animals. This results in greater airflow through one nostril with ...
The most precise methods to date to measure sniffing involve direct intranasal measures through use of a temperature probe, called a thermocouple, or a pressure sensor. These can be inserted temporarily into the nares or implanted surgically. [4] [6] The basic principles of operation are shared between the temperature and pressure devices ...
[35]: 140 The dog's visual system has evolved to aid in hunting. [28] Dogs have been shown to be able to discriminate between humans (e.g., identifying their human guardian) at a range of between 800 and 900 metres (2,600 and 3,000 ft); however, this range decreases to 500–600 metres (1,600–2,000 ft) if the object is stationary.

In humans, the nasal cycle is the normal ultradian cycle of each nostril's blood vessels becoming engorged in swelling, then shrinking. The nostrils are separated by the septum. The septum can sometimes be deviated, causing one nostril to appear larger than the other. With extreme damage to the septum and columella, the two nostrils are no ...
As the temperature climbs and summer gets sweaty, we must think about our dogs! Canines regulate heat differently than humans. While we can sweat to stay cool, dogs pant to release heat.
A dog's nose is significantly colder than their body temperature. This makes it more sensitive to thermal radiation. Dogs can thus detect even weak levels of warmth. [8] Dogs are able to smell from birth and develops during the first two weeks of their life. Dogs can also learn scents in the womb.
