Lungs

The bronchopulmonary lymph nodes are responsible for draining lymph from the lungs, bronchi, and trachea. They help in filtering and removing pathogens, dead cells, and other foreign particles from the respiratory system. This process aids in immune response and maintaining overall respiratory health.

Sections of the lungs are called lobes. The right lung has 3 lobes and the left lung has two, which allows room for the heart.

The pleural membrane is a double-layered serous membrane found in the thoracic cavity. The outer layer is called the parietal pleura and lines the thoracic wall, and the inner layer is called the visceral pleura and covers the lungs.

The membranes produce lubricating serous fluid that causes them to adhere closely to one another. This holds the lungs to the thoracic wall allowing easier movement during breathing.

The first thing that happens to most people is called high altitude pulmonary edema, a build up of fluid in the lungs that makes it hard for them to breathe. In very susceptible individuals this can happen at as low as 1500 meters above sea level (air pressure around 85 kPa).

At partial pressures of oxygen less than about 10 kPa, your lungs can no longer efficiently absorb oxygen from the air. If you're breathing normal air, this happens at an overall pressure of around 50 kPa, corresponding to a height of about 6 km above sea level.

Should the overall air pressure drop below around 10 kPa (normal atmospheric pressure is around 100 kPa and the pressure at the top of Mount Everest is around 30 kPa), water evaporation would become significant. By the time the pressure dropped to 6 kPa, all the moisture in your body would be evaporating so fast it would literally be boiling.

The time a bullet stays in the air, also known as time of flight, can vary depending on the type of firearm and the bullet's velocity. On average, most bullets travel at supersonic speeds, so they can cover a distance of a few hundred meters in less than a second. Generally, for typical firearms, the time of flight is usually less than a second.

The crisscross structures holding the menisci in place are called ligaments. These ligaments help stabilize the menisci within the knee joint and aid in preventing excessive movement or displacement of these important cartilaginous structures.

Hemoglobin is the compound in red blood cells that carries oxygen from the lungs to body cells. The oxygen combines readily with the ion in hemoglobin, and hemoglobin can carry more than twenty times its own volume in oxygen. After releasing oxygen to the cells, hemoglobin collects carbon dioxide and carries it to the lungs where it is exhaled.

Drinking milk, getting at least 8 hours of sleep, exercise, eating fruits and vegetables, and eating a good diet.

Those things should help the growth of the human body.

It may take a while though

Air, like all fluids, has no "natural movement." All its movements are determined by a wide variety of factors. One of those factors is its velocity.

Slow moving air tends to be smooth and laminar. But fast moving air tends to break up and create eddies and swirls.

There are other factors as well. For example, what surfaces is that air passing over? If the surface is a designed surface of a supersonic jet, the velocity of the air passing over that jet's surface can remain laminar. In fact it must remain laminar for the jet to fly safely at supersonic speeds.

Bottom line, there is no "natural movement." How that air flows at any given speed depends in large part on the surfaces that the air is blowing over.

Bronchioles are located in the lungs and are part of the respiratory system. They are smaller airways that branch off from the bronchi and carry air to the alveoli for gas exchange.

Haemoglobin in the carry oxygen to all parts of the body in the form of oxyhaemoglobin.It leaves oxygen,carries carbon dioxide from the body cells forming carboxyhaemoglobin to carry the carbon dioxide to the lungs to be passed out through the nose.

Various molecules have to get from where they are to where they are needed and can be used. Diffusion is just a random movement of molecules. Oxygen is not PUT into the blood cells, for example. It is brought into a close enough proximity to the red blood cells that DIFFUSION is likely to bring it close enough to be captured by the cells to be carried to the other cells. There, it will be released and DIFFUSE to the cells and be used (by the mitochondria) to complete the necessary oxidative processes.

when you inhale..(take in oxygen)..the air fills up the lungs, the ribcage expands and the muscle sheet called the diaphragm pushes downward and flattens as you inhale ..whn you ehale the muscle returns back to domed-shape

The job of the excretory system is to remove waste and toxins from the body. It includes organs such as the kidneys, liver, and skin that filter waste products from the blood and eliminate them through urine, feces, and sweat. This system helps maintain the body's internal balance by regulating fluid levels and removing harmful substances.

There are approximately 0 rods located in the human fovea. The fovea is the central part of the retina, and it contains mainly cones, which are responsible for color vision and visual acuity in bright light. Rods, which are responsible for vision in low light, are more abundant in the periphery of the retina.

Lungs are adapted to their job of exchanging oxygen and carbon dioxide through a large surface area with millions of tiny air sacs called alveoli, which allows for efficient gas exchange. The walls of the alveoli are thin and surrounded by a network of small blood vessels, enabling oxygen to diffuse into the blood and carbon dioxide to diffuse out. The lungs are elastic and can expand and contract to support breathing.

your diaphram contracts and you inhale the air then the air goes to your lungs where it goes throughout your blood stream then the old oxygen picks up the carbon and then you exhale the oxygen with the carbon

Use a stong index arterial fluid with special additives (San Veino in suspension with soap is the best, but Omega is great, too). I use nearly waterless solution. A multi-point injection is advised as is hypodermic injection of the most affected areas. Use a strong cavity fluid after thorough aspiration and keep all incisions/punctures open if possible to let gas escape. External packs are advised to cauterize skin slip and embalm topically. Complete disinfection of instruments and the embalming area (clean EVERYTHING) is essential to prevent the spread of tissue gas.

House Dust Mites Dermatophagoides pteronyssinusand D. farinae are the most common species of house dust mites in North Carolina . These tiny mites are most abundant in warm, humid areas. Contrary to popular belief, house dust mites do not bite or sting. They feed on shed human skin scales that collect in the dust on furniture, particularly mattresses, and on carpeting below beds. House dust mites are important medically because they produce allergens in their secretions and excrement. Inhaling airborne house dust containing mite feces and cast skins is a common cause of asthma in young children. Products containing benzoyl benzoate and other ingredients are often used for severe infestations of house dust mites. However, the long-term solution to reducing a house dust mite problem is sanitation and environmental modifications: * Vacuum (possibly with a HEPA-filtered vacuum cleaner) frequently and thoroughly to remove mites and the organic debris on which they feed. Target critical areas, such as: * ** mattresses and bed frames ** rugs and carpets (especially under beds) ** overstuffed furniture (and the area underneath) * Change air conditioner filters frequently and maintain low (less than 50%) humidity indoors to reduce conditions favorable to dust mites. * Encase mattresses and pillows in plastic covers and change bed linen frequently to help prevent mite populations from building up

The law of diffusion states that particles will naturally spread out from an area of high concentration to an area of low concentration, resulting in a uniform distribution over time. This process occurs due to the random motion of particles and is governed by factors such as concentration gradient, temperature, and molecular size.

Yes, in a way. They take out the carbon dioxide from the blood and put the oxygen back in the blood. The sole purpose of the blood is to get oxygen from the lungs and bring it to other body parts and take the carbon dioxide back to the lungs.

The membranes in the lungs that produce a sticky secretion are called the mucus-producing goblet cells that line the respiratory tract. This mucus serves to trap dust, bacteria, and other particles, helping to keep the airways clear and protecting the lungs from potential infections.

Good question! The respiratory tube is placed in front of the food tube. The food should normally enter the respiratory passage. That would have disastrous results. But the same is protected by the flap called as epiglottis. This stands upright normally, when you breath. It closes temporarily the opening of the respiratory passage, when you are swallowing the food bolus. The food you swallow is either liquid or made into bolus by the saliva. You can not swallow the powder. It may enter the respiratory tract. This is one of the beautiful mechanism. You have thousands of such designs in your body. I believe that such designs are possible for God only.

In a person with emphysema, there is a significant loss of intrinsic elastic recoil in the lung tissue. This loss of elastic recoil occurs as the disease destroys the walls of the alveoli. Airway resistance is also increased as the lung tissue in general becomes more flimsy and exerts less mechanical tethering on the surrounding airways. Thus the lung becomes overly compliant and expands easily. Conversely, a great effort is required to exhale as the lungs can no longer passively recoil and deflate. A noticeable and exhausting muscular effort is required for each exhalation. Thus a person with emphysema exhales slowly. Thus decreasing the tidal volume.
