Respiratory System

I advise you to download this book, it talks about healthy food, exercises and how to deal with stress

The mucus layer protects the respiratory tract by trapping bacteria and dust, not allowing them to enter the body. Mucus filters the air during inhalation and keeps the tissues from becoming too dry.

- I'm not sure I understand what you are asking. A tidal volume is what we use to measure how many liters a person can hold in their lungs. It's normally about 10-15mls/kg of ideal body weight. That number can be used to identify certain respiratory diseases. Its also what most ventilators are set on when a person needs ventilatory support.

There is exchange of CO2 and O2 in the lungs of aerobic vertebrates. The process is generally referred to as gas exchange. It depends on what organism you're talking about. It could be the skin, gills, lungs, or any other structure. In the lungs is the Alveoli.

Being Ill ca. influence it pretty well.

In the respiratory system, we see the exchange of gases. In this gas exchange, carbon dioxide (CO2) leaves the blood and goes into air in the lungs, and oxygen (O2) leaves the air in the lungs and goes into the blood. It is this gas exchange, which occurs in the alveoli, that permits oxygenation of the blood and keeps us alive.

AIR SACS are the FUNTIONAL UNIT of human respiratory.

while we regard ALVEOLI as STRUCTURAL UNIT of human respiratory system.

The muscular system uses the bones for their action. Without bones muscles would be useless at distance. Bones act like lever arms to increase the force produced by muscles. The digestive system gives nutrients to the muscles.

The circulatory system!

The slitlike passageway between the vocal cords is the glottis.

Capillaries are the thin-walled vessels that allow oxygen and carbon dioxide exchange. Their thin walls make it easy for gases to diffuse across the membranes.

inhale:- the air pressure in the lungs decreases and air moves in.

exhale:-air pressure in the lungs increases and air moves out.

There are about 300 million alveoli in each of your lungs. These tiny air sacs provide an ideal site for the diffusion of gases into and out of the blood - also known as gaseous exchange.

The alveoli have a very large surface area - in fact if all of the alveoli in your lungs were spread out flat

they would cover the area of a tennis court.

This large surface area is the result of all the alveoli being small spheres - it is another example of the

importance of the surface area- to-volume ratio.

If your lungs were simply two large balloon-like structures, the surface area wouldn't be big enough for you to get enough oxygen by diffusion to supply the needs of your cells.

But each alveolus is a very tiny sphere. The smaller the radius of a sphere, the bigger the relative surface area - halving the radius increases the relative surface area by a factor of four.

The millions of tiny alveoli in the human lungs are a very effective adaptation which provides a huge surface area for gaseous exchange into and out of the blood.

The alveoli have a good air supply from the bronchioles and a rich blood supply.

This is vital for successful gaseous exchange because it maintains a steep concentration gradient for oxygen from the air in the alveoli to the blood, and for carbon dioxide from the blood to the alveoli.

Oxygen can just diffuse directly into the unicellular organism. The same diffusion occurs in a multicellular organism, but the respiratory system has to get the oxygen close to the target cells in order for the oxygen to diffuse. But if there's only one cell to supply oxygen to, no respiratory system is needed.

Destruction of alveoli reduces the surface area for gas exchange

• amphibians breath with the help of both gills and lungs. example frog. frog in its larval stage is called a tadpole and its respiratory organ is gills. in its later stages of life (adult) its respiratory organs changes into lungs

no they are to small to have a respiratory system or organ so they breath through there cell membrane

Pie is a very tastey dessert.

They hold their breath until they turn green. That is how they get the skin color. Then they swallow their youngest children while fighting underwater dragons. When they kill the dragon, they drink its blood to develop gills, and they live happily ever after

Normal atmospheric pressure of air is 150 mm Hg for oxygen (around 610 mm Hg for nitrogen). This equals 760 mm Hg in the atmosphere. In the alveoli, however, pressure is lower because 30% is being used by tissues, leaving 70% of 150 mm Hg oxygen in the alveoli. That means around 100-105 mm Hg is the partial pressure of oxygen in alveoli.

What causes you to breath through only one hole from your nose is the fact that the other hole is blocked by mucus, or "boogers" if the mucus has dried up. If this not the case then you should ask your doctor.

Sometimes this is normal. It may be the body's way to get you to turn over in your sleep and prevent bed sores. What happens is that the turbinates in your sinuses swell.

Circulatory system carries the oxygen that the respiratory system brings in. If the blood isn't moving, neither is the oxygen. If either system fails, the other system fails shortly after. Brain death occurs in 6 minutes without oxygen.
