Lungs

The respiratory tracts are divided into three segments. Scientists believe that there are 20 to 23 divisions. The respiratory tract is part of the process of respiration in a human body.

Expiratory reserve volume is decreased in a patient with emphysema. This patient will struggle to breathe out because air is getting trapped within the lungs. There is also an increase of co2 in the blood because of the inability for the patient to exhale.

when its dead air and you cant use it to breath

The CO2 or carbon dioxide is removed by the alveoli from the blood. The carbon dioxide is replaced with oxygen. The blood is then full of oxygen. Alveoli are tiny sacs in the lungs, surrounded by capillaries.

Lungs.

Cilia inside the nose filter the air for most dust, allergens, viruses, and bacteria.

Breathing starts at the nose and mouth. You inhale air into your nose or mouth, and it travels down the back of your throat and into your windpipe, or trachea. For your lungs to perform their best, these airways need to be open during inhalation and exhalation and free from inflammation or swelling and excess or abnormal amounts of mucus.

a artery actually move the blood to your lung but th perodic vane helps like a police officer to stop and move the blood

swimming and track running both require a large lung capacity as does singing

Alveoli

Bronchogenic carcinoma

the simple answer is drowning. Blood is a fluid just like water, and it causes the same effect as drowning.

First it's larger, second the left lung is sharing space with your heart..

The air you breathe in through your nose goes through your nostrils, pass something called turbinates (also called concha, which warm the air), then enter the nasopharynx, which is the area above your uvula (You can´t see it witout a proffessional mirror). Then it enters the oropharynx (the very back of your thoat) and from there it follows the same path as the air you breathe in through your mouth. Namely Larynx-->Trachea-->Bronchi--> Alveoli. From there the air diffuses into bloodvessels lining the alveoli.

The vacuum created by down-ward movement of the diaphram.

performed in a specialized organ transplantation hospital. Every transplant hospital in the United States is a member of the United Network for Organ Sharing (UNOS) and must meet specific requirements.

1. The blood vessels are completely surrounding the alveoli for easy diffusion into the blood vessels

2. The alveoli and the blood vessels are made up of a very thin layer of cells. a single layer of simple squamos epithelium. For easy diffusion

3. There is a moist layer layering the alveoli which the gases dissolve into. This aids diffusion.

4. The blood vessels are very thin, this ensures that the red blood cells enter them in a single file row. This enables maximum diffusion.

5. The shape of the red blood cells is flat, this is increases surface area for maximum absorption.

6. The alveoli itself are round, balloon shape. This also increases surface area for maximum absorption.

lots of things could damage your lung smoking could decrease the amount of surfactant, which is a fluid function to decrease the surface tension and to prevent your lung from collapsing.

and then there is air pollutions, chemicals, asbestos.

W E E D es good for yu buh fcuuksUP yuer heead !

There is 75 square meter of gas exchanging surface area that exists in the lungs. It is more or less the size of a standard tennis court.

Blockage of the throat or airways. Asthma and other breathing problems resulting from smoking or infections. Swelling when sick and mucus can also harbor breathing and also affect gas flow. Carbon monoxide also can affect the chemical balance.

Acetylcholine is a bronchoconstrictor.

Defining Social Security Disability Benefits:

The SSA has a very rigid definition of who is disabled. To receive SSI or SSDI benefits a person must provide evidence that they are permanently disabled and this condition will last at least one year, or result in their death. No benefits are awarded for a partial or short-term disability. Documenting a COPD Disability:

The most important thing for a COPD patient to do is to see a doctor on a regular basis. While at the doctor's office, this is your opportunity to help build your COPD disability case. Remember to win benefits you'll need to provide documentation of your disability. The notes and records your doctor maintains on file are critical evidence to help support your claim I've summarized your answer on this page because it allows better formatting:

Thank you

Inspiration causes a drop in thoracic pressure, so the blood pressure in the area may drop, so the feeling of the pulse may feel weaker (though this would have to be an extreme case). It also can cause splitting of the second heart sound as the lungs take in more blood.
