Tears

Tearing (/ˈtiərɪŋ/), lacrimation, or lachrymation, (from Latin lacrima, meaning "tear") is the secretion of tears, which often serves to clean and lubricate the eyes in response to an irritation of the eyes. Tears formed through crying are associated with strong internal emotions, such as sorrow, elation, emotion, love, awe or pleasure. Laughing or yawning may also lead to the production of tears.

Physiology

In humans, the tear film coating the eye, known as the precorneal film, has three distinct layers, from the most outer surface:

Having a thin tear film may prevent one's ability to wear contact lenses, as the amount of oxygen needed is higher than normal, and contact lenses stop oxygen from entering the eye. Eyes with thin tear film will dry out while wearing contact lenses. Special eye drops are available for contact lens wearers. Certain types of contact lenses are designed to let more oxygen through to the eye.

Drainage of tear film

The lacrimal glands secrete lacrimal fluid, which flows through the main excretory ducts into the space between the eyeball and lids. When the eyes blink, the lacrimal fluid is spread across the surface of the eye. Lacrimal fluid gathers in the lacrimal lake, and is drawn into the puncta by capillary action, then flows through the lacrimal canaliculi at the inner corner of the eyelids entering the lacrimal sac, then on to the nasolacrimal duct, and finally into the nasal cavity. An excess of tears, as with strong emotion, can thus cause the nose to run.

Inhaler

An inhaler (or puffer) is a medical device used for delivering medication into the body via the lungs. It is mainly used in the treatment of asthma and Chronic Obstructive Pulmonary Disease (COPD). Zanamivir (Relenza), used to treat influenza, must be administered via inhaler.

To reduce deposition in the mouth and throat, and to reduce the need for precise synchronization of the start of inhalation with actuation of the device, MDIs are sometimes used with a complementary spacer or holding chamber device.

Decongestant inhalers are popular over-the-counter remedies for nasal congestion in the upper respiratory tract.

Types

Metered-dose (MDI)

The most common type of inhaler is the pressurized metered-dose inhaler (MDI). In MDIs, medication is typically stored in solution in a pressurized canister that contains a propellant, although it may also be a suspension. The MDI canister is attached to a plastic, hand-operated actuator. On activation, the metered-dose inhaler releases a fixed dose of medication in aerosol form. The correct procedure for using an MDI is to first fully exhale, place the mouth-piece of the device into the mouth, and having just started to inhale at a moderate rate, depress the canister to release the medicine. The aerosolized medication is drawn into the lungs by continuing to inhale deeply before holding the breath for 10 seconds to allow the aerosol to settle onto the walls of the bronchittus and other airways of the lung. Some inhalers are made to act instantly in case of an asthma attack, and others are made to act later.

Inhaler (Foals song)

"Inhaler" is a song by British band Foals. It is the lead single from their third album, Holy Fire. The track and music video were released on 5 November 2012 in the United Kingdom. The official video was directed by Foals' frequent collaborator Dave Ma and features artwork from Tinhead. The single graphic design was done by Leif Podhajsky

Inhaler won the award for best track of 2012 at the NME awards held in February 2013. The single was also the group's first chart appearance on any American singles chart, peaking at number 20 on the Billboard Alternative Songs chart in early 2013. Shortly after its peak on that chart, the song crossed over to hard rock radio and ultimately peaked at number 29 on the Billboard Hot Mainstream Rock Tracks chart.
