Nasal cavity

licking her nose? A person has around five million smell receptors in her nose. Your dog has between 20-300 million. When a dog is actively checking something out, her nose produces a thin layer of mucus. This sticky mucus covers her nose, and picks up thousands of chemical scent signatures. When she licks her nose, those chemical scents are transferred to the olfactory glands in the roof of her mouth, allowing her to separate and identify them. If you look closely at your dog’s nose, you will see that on each side of her nostrils is a slit. This design enables the dog to inhale through the nostril, and exhale through the slits. The nostril itself is also divided into two parts – one passage is for breathing, and separate passages called nasal turbinates take in scents and odors. That nose is doing double-duty! A dog also licks its nose to clean it, especially after snuffling into the grass and dirt outside, or after eating and drinking. Why is my dog’s nose running? A runny nose can mean many things. A runny nose with clear, watery discharge is typically normal, and usually attributed to allergies. Allergies are very common in dogs of all breeds, and most dogs start to exhibit allergic symptoms between the ages of six months and two years. Like humans, when a dog has an allergic reaction, the lacrimal glands that produce tears ramp up to wash any irritating material out of the eyes. Since the tear ducts are connected to the sinuses, the whole mechanism starts…

for a whale (Ridgway et al. 2012). White whales produce sound through the pressurization of the nasal cavities, as has been shown by placing catheters in these cavities of whales. After placement of the catheter into a whale, it undergoes a series of tasks that will cause the whale to use echolocation in order to detect a specific object within its immediate surroundings. The whale will then vocalize as a means of conveying that it has found the object. During this process, the catheter…

Oral/nasal cavity- The nasal cavity is the primary intake for air for the respiratory system, consisting of cartilage, muscle and bone. It allows for inhalation of air into the body and warms the air as it enters filtering the air by removing dust, pollen, and other contaminants, purifying the air before it is passed to the inner body. The secondary exterior opening is the oral cavity, it allows for larger quantities of air inhalation, it also has less distance to travel allowing more air to…

It transports air between the lungs and the body’s exterior the nose, pharynx, mouth, larynx, trachea, bronchi, and bronchioles. Nose and Nasal Cavity Structure: The nose and nasal cavity is line with cilia and capillaries. It secrets mucus, filters debris out in the air and warms the air to 37 degree centigrade. The nose is the face structure comprising of cartilage, bone, muscle, and skin that supports and protects the anterior portion of the nasal cavity; whilst the nasal cavity is the…

the size and the shape of the pharyngeal, oral, and nasal cavities, which provides the quality and uniqueness of the voice from the vocal tract with airflow and sound. Airflow is converted into air pressure by articulators, which…

Probiotics increase immunity and decrease inflammation caused by allergens. There are several strains that help to relieve spring allergies, including Lactobacillus acidophilus, Bifidobacterium lactis and Escherichia coli Nissile. Steam Showers - After you have been outdoors, launder your clothes and take a shower. Allergens stick to your skin, hair and clothes, so it is essential that you remove your clothing and take a shower to prevent them from spreading to other surfaces in your home.…

The nasal septum is a flesh and membrane-covered cartilage wall dividing the nose into right and left nostrils. Fashion-forward individuals pierce the nasal septum, but perforations can also result from illnesses such as syphillis or rare inflammatory disorders, nose picking and drug abuse. A perforated septum 's symptoms include nose bleeds, recurring infections, sinusitis, whistling, congestion and a bad smelling crust. Doctors can monitor small perforations while managing tjem with ointments,…

Congestion It’s the time of the year again when our nose is exposed to cold and starts to run, our chest are so congested and nothing feels good. In short, congestion season is here. https://en.wikipedia.org/wiki/Nasal_congestion Nasal congestion is caused by many factors, but its effects range from a simple irritation to older children and adults to a life-endangerment condition for infants, like • Can obstruct our hearing and speech. • Can interfere with sleep by causing snoring. • Can…

Evaluation of the physiologic effects of high-flow nasal cannula (HFNC), which “is a heated, humidified, high-flow oxygen delivery system that can generate total gas flows of up to 60 L/min with an adjustable FIO2”, compared to conventional oxygen therapy (COT) for patients with hypoxemia and acute dyspnea in the emergency department was the focus of this study published in the American Association for Respiratory Care Journal (Rittayami, Tscheikuna, Praphruetkit, & Kijpinyochai, 2015). The…

Case study This case study is going to describe the details of a chest examination undertaken on a 36 year old man who was involved in a road traffic collision (RTC) from the emergency department. The request card for the examination had the following clinical details: 'Cyclist involved in RTC, query pneumothorax'. Pneumothorax is a condition whereby the pleural cavity holds an accumulation of air resulting in the collapse of the lungs due to the pressure exerted on the lungs by the air…
