Respiratory System

smoking can give you 3 kinds of diseases: cancer, heart attacks, and strokes.

The word aerobic means to use oxygen while anaerobic doesn't need oxygen. The products of aerobic respiration are carbon dioxide and water and energy (ATP). The products of anaerobic respiration are oxygen and energy (ATP).

the epiglottis closes over the glottis in a reflex action when food is swallowed. This prevent food from entering the respiratory system

hyaline membrane disease

Fine hair and mucus act as the first line of defense in the nasal passage. They keep foreign particles that could cause illness from entering the body. The hairs (cilia) and mucus along the nasal cavity are responsible for trapping dust and other particles in the air you inhale and sweeping it out again. They work in the same way as an air filter does on a motor vehicle's engine.

generally accepted answer - oxygen gas (O2) and carbon dioxide gas. But also water vapor, some nitrogen, and a lot of other trace gases.

The stems would represent the brochioli and the grapes would represent the alveoli.

Men have larger lung capacities than women. Tall people also have larger lung capacities than short people. It is said that people aged 20-25 have larger lung capacities than other age groups, Its because by the time you have reached your twenties your lungs have reached their full capacity, but when you are a kid then your lungs aren't fully developed so they don't have a large capacity. From when you are 20 your lung capacity starts going down so an old man has about the same lung capacity as a very small boy.

The respiratory system draws oxygen into the lungs. The circulatory system moves blood into the lungs to pick up the oxygen and then brings the oxygen to cells in the rest of the body.

In manual ventilation you can increase the PaO2 by hyperventilating the patient, by increasing the respiratory rate and/or by increasing the volume of air that you deliver to the patient. If using a BVM for example, compressing the bag faster and/or harder will increase the arterial oxygen pressure, but there is a limit to what you can do with manual ventilation. Perfusion in the lungs has a major impact on PaO2. Also, the blood chenistry (anemia or CO2 poisoning) for example will dramatically decrease the PaO2. Sometimes no matter how much you hyperventilate the person, low PaO2 can't be corrected.

The Epiglottis

bronchioalveolar lavage

where does the vast majority of pulmonary emboli orginate

It is found in the upper throat and is referred to as the Epiglottis.

It's purpose is to close over your throat as you're eating to stop food going to your lungs

-respiratory acidosis is when the pH of your arterial blood becomes acidic. Since C02 is acidic, when you don't ventilate properly, this builds up in your system and makes your blood acidic. Bicarbonate is a base. In most cases, bicarb will begin to store up in the body to reverse/compensate for the acidosis.

The alveoli branch from the bronchioles and are responsible for gas exchange with the pulmonary capillaries. They come in close contanct with the capillaries so the exchange of O2 and Co2 can occur rapidly and easily.

nasal cavity, pharynx, epiglottis, larynx, trachea, right and left bronchus, right and left lung, diaphragm

The lungs clean your blood, the other strucs allow you to talk.

these are the pipes by which oxygen enters the lungs and co2 exits

The deer is quite the interesting creature. It breaths with its lungs while on land, and secretively at night it sneaks into the water and gills magically appear on its body allowing it to take oxygen from the water like a fish. It does this to hide from poachers in the night and also because the water is refreshingly cool.

Pulmonologists are physicians who specialize in evaluating and treating the lungs.

Respiratory therapists carry out the orders of physicians to provide respiratory treatments. They are also involved in ICU care when a patient is on a ventilator.

Nurses teach all aspects of lung health and about lung diseases and medications, treatments, self-help or home therapies, etc.

5 parts of the respiratory system are as follows: lungs, trachea, heart, larynx, pharynx.
