It helps them understand my heart position when my lungs fill with air.

It's more amorphous, a thicc blob of color that you can fill with air wherever you happen to be: at the beach, the park, your airport gate.

To ascend, the pilot lets the helium fill the main chamber; to descend, the helium is compressed and sent back into the tanks, enabling the chamber to fill with air.

"I've heard condoms called sewer lilies because they fill with air or gas and float to the top," said Cynthia Finley, the director of regulatory affairs at the National Association of Clean Water Agencies.

The best inflatable beach chair: WEKAPO Inflatable Air Lounger ($35.98) If you're not into a conventional beach chair, the Wekapo Inflatable Air Lounger is basically a dry bag that you fill with air to make couch-sized.

If one of the canopies accidentally deploys inside the plane while the rear cargo ramp is open in preparation for jumping, the slight vacuum created could cause the parachute to fill with air and yank the wearer out of the plane.

After an explosive decompression within an aircraft, a heavy fog may immediately fill the interior as the relative humidity of cabin air rapidly changes as the air cools and condenses. Military pilots with oxygen masks have to pressure- breathe, whereby the lungs fill with air when relaxed, and effort has to be exerted to expel the air again.

In the alveolar walls there are interconnecting air passages between the alveoli known as the pores of Kohn. The alveolar septa that separate the alveoli in the alveolar sac contain some collagen fibers and elastic fibers. The septa also house the enmeshed capillary network that surrounds each alveolus. The elastic fibres allow the alveoli to stretch when they fill with air during inhalation.

The HPE units contain and control the compressed helium and allow the overall volume of helium to be reduced or increased, enabling the air vehicle to become heavy or buoyant in a controlled manner. The compression of helium into the HPE’s creates a negative pressure within the Aeroscraft Aeroshell, permitting air-expansion chambers to fill with air, which acts with reduced helium static lift to make the Aeroscraft heavier to compensate for adjustments in load.

The contraction of the diaphragm creates a negative pressure within the pleural cavity which forces the lungs to expand resulting in passive exhalation and active inhalation. This breathing process can be made forceful through the contraction of the external intercostal muscles which forces the rib cage to expand and add to the negative pressure in the pleural cavity causing the lungs to fill with air. The fluid in the cavity provides lubrication and cushioning.

Females of the water spider Argyroneta aquatica build underwater "diving bell" webs which they fill with air and use for digesting prey, molting, mating and raising offspring. They live almost entirely within the bells, darting out to catch prey animals that touch the bell or the threads that anchor it.Schütz, D. and Taborsky, M., (2003). Adaptations to an aquatic life may be responsible for the reversed sexual size dimorphism in the water spider, Argyroneta aquatica.

Take for instance the design and production of a car. If for example the vehicle’s air bags are found to automatically fill with air after driving long distances, this will without a doubt lead to customer complaints (or hopefully problem reports during the testing phase). In turn, these produce a change request (see Figure 2 on the right), which will probably justify a change. Nevertheless, a – most likely simplistic – cost and benefit analysis has to be done, after which the change request can be approved.

They live almost entirely within the bells, darting out to catch prey animals that touch the bell or the threads that anchor it. A few spiders use the surfaces of lakes and ponds as "webs", detecting trapped insects by the vibrations that these cause while struggling. Net-casting spiders weave only small webs, but then manipulate them to trap prey.

The increase in volume of the entire trunk cavity reduces the air pressure in all the thoraco-abdominal air sacs, causing them to fill with air as described below. During exhalation the external oblique muscle which is attached to the sternum and vertebral ribs anteriorly, and to the pelvis (pubis and ilium in Fig. 17) posteriorly (forming part of the abdominal wall) reverses the inhalatory movement, while compressing the abdominal contents, thus increasing the pressure in all the air sacs. Air is therefore expelled from the respiratory system in the act of exhalation. Fig.

The internal oblique performs two major functions. Firstly as an accessory muscle of respiration, it acts as an antagonist (opponent) to the diaphragm, helping to reduce the volume of the chest cavity during exhalation. When the diaphragm contracts, it pulls the lower wall of the chest cavity down, increasing the volume of the lungs which then fill with air. Conversely, when the internal obliques contract they compress the organs of the abdomen, pushing them up into the diaphragm which intrudes back into the chest cavity reducing the volume of the air-filled lungs, producing an exhalation.

The failure of the hole between the right and left atrium to close shortly after birth is the cause behind ASD primium. During fetal development blood will pass from the umbilical cord and flow into the left atrium through a hole between the two atria. Once a baby is born and the lungs begin to fill with air, the blood flow of the heart changes; a tissue flap (septum primium) normally closes the hole (foramen ovale) between the two atria and becomes part of the atrial wall. During ASD primium, after birth the hole is not completely closed allowing deoxygenated blood to flow into the left atria from the right atria.

Normally, the ratio of ventilation to perfusion is about one-to-one; the volume of air entering the alveoli (ventilation) is about equal to that of blood in the capillaries around them (perfusion). This ratio is reduced in pulmonary contusion; fluid- filled alveoli cannot fill with air, oxygen does not fully saturate the hemoglobin, and the blood leaves the lung without being fully oxygenated. Insufficient inflation of the lungs, which can result from inadequate mechanical ventilation or an associated injury such as flail chest, can also contribute to the ventilation/perfusion mismatch. As the mismatch between ventilation and perfusion grows, blood oxygen saturation is reduced.

Blood passes from the umbilical cord and flows into the left atrium through an opening called the foramen ovale; the formaen ovale is a hole between the two atria. Once a baby is born and the lungs begin to fill with air and the blood flow of the heart changes, a tissue flap (somewhat like a trap door) called the septum primium closes the foramen ovale or hole between the two atria and becomes part of the atrial wall. The failure of the hole between the two atria to close after birth leads to a disorder called ASD primium. The most common problems with an opening found in the heart with Lutembacher's syndrome is Ostium Secundum.

During inspiration, the chest wall expands and causes the intrathoracic pressure to become more negative (think of a vacuum). The increased negative pressure allows the lungs to fill with air and expand. While doing so, it also induces an increase in venous blood return from the body into the right atrium via the superior and inferior venae cavae, and into the right ventricle by increasing the pressure gradient (blood is being pulled by the vacuum from the body and towards the right side of the heart). Simultaneously, there is a reduction in blood volume returning from the lungs into the left atrium (the blood wants to stay in the lungs because of the vacuum surrounding the lungs, and PVR is lower because of lung expansion).

A horo was around 1.8 m (6 ft) long and made from several strips of cloth sewn together with a fringe on the top and bottom edges. The cloth strips were sewn together and formed into a sort of bag which would fill with air like a balloon when the wearer was riding a horse.Transactions of the Asiatic Society of Japan, Asiatic Society of Japan, The Society, 1881 p.275–279 A light framework of wicker, bamboo or whale bone known as an oikago, similar to a crinoline, which is said to have been invented by Hatakeyama Masanaga during the Ōnin War (1467–1477),Secrets of the samurai: a survey of the martial arts of feudal Japan, Oscar Ratti, Adele Westbrook, Tuttle Publishing, 1991 p.
