Respiratory System

Just as when you exercise you breathe faster, when you sleep your breathing slows.

Your body will adjust it's rate of breathing to accomodate it's needs at the time, when you are sleeping less oxygen is needed since you are inactive.

The respiratory tract consists of organs and tissues such as the nose, pharynx, bronchi, trachea and alveoli. The respiratory tract starts at the nose.

Yes It Does :)

Blood containing carbon dioxide flows from veins throughout the body to the heart, and then the heart pumps it to the lungs. Small air sacs (alveoli) in the lungs remove the carbon dioxide from the blood and release it into the lungs where it is exhaled.

Right when you stop holding your breath, your breath rate will certainly increase due to the body's increased need to expel the built up CO2 as well as inhale the lacking O2.

Air stops moving into the lungs when the air pressure inside the lung is equal to the pressure of the air outside the body (the atmospheric pressure). The body creates negative air pressure inside the lungs by moving the diaphragm down and the chest wall out. This expands the volume of the lungs, creating negative air pressure, and air rushes in to fill the lungs.

no that's a good question

u take a DEEP BREATH when u think about it

long. can't you imagine that, having stupid alcohol in you. i mean what is his kind of question? and especially in you respiration system, you cant breath, and you go awfully drunk! hope this helped you, although i only wanted to please you by answering! go to the doctors then, cuz i don't really know...

endotracheal

The heart, lungs and the brain. Oxygen enter the lungs, the brain motor response of what kind of air you inhaled, and goes to the heart, goes out again to the lungs through exhalation, which releases CO2.

Well, if you had asked "What lifestyle activity definitely has a negative impact on the respiratory system," I would answer "smoking."

The respiratory system of most non-aquatic animals is entirely enclosed in the human body and connected with the lungs. Many aquatic animals have developed open respiratory systems that include features like the gills.

The respiratory system is the system in your body make of choclate and bricks

The faster you breathe the faster your heart rate gets (more oxygen to pump around)

The slower you breathe the slower your heart rate gets.

Although correct, this answer does not explain why your heart rate increases. If you are breathing quickly, you are not getting as much oxygen in as if you were breathing normally. Therefore, your heart rate increases because your heart is trying desperately to pump the required oxygen throughout the body that isn't available. For example, if a restaurant is understaffed, the remaining workers will work twice as hard. With not enough oxygen, your heart needs to work harder to deliver the available oxygen.

The deeper breaths you take, the slower your heart rate will be, due to the excess of oxygen; your heart won't need to work as hard with lots of oxygen available.

the water contents in the breathe air gets condensed, on the surface of the mirror and appears foggy

Normally no.

While brain cells can die off after as little as 3 minutes without oxygen; under normal conditions your body will force you to breath before you hit the point where brain cells begin to die.

The only way you could force yourself to lose brain cells from holding your breath would be to add additional complications that prevent the bodies natural danger response from saving you.

In other words: if you add a plastic bag covering the mouth, or hold your breath under water or use some other extreme method of blocking new air flow than yes it would be possible to kill brain cells; however, at that point you are no longer actually "holding your breath" your body would be trying to breath but you would be depriving it of oxygen through additional methods.

You will have at least attempted to breath before any brain cells will die, the only question at that point is if there is air available for you to breath or are you immersed in water, plastic or something else which prevents it from happening.

Even in the most extreme cases of breath holding, the most you could do is force yourself to pass out, at which point your body will begin breathing and prevent brain damage; unless of course you have covered your air passages in some other way.

Smaller birds and mammals have a higher metabolic rate than larger ones because they have a higher surface to volume ratio. That means they lose heat faster, and don't have as much body mass to generate heat. To keep their body temperature well above the temperature in their environment, they have to burn more fuel (food), breathe in more oxygen, and pump blood faster. Cold blooded animals don't show the same big differences in metabolism relative to their size.

Breathing rate is most likely to increase if you are involved in physical activities like running or climbing a stair or cycling or working out in a gym.

When you are involved in a physical activity, the various muscles of your body that are being used will require a lot of oxygen and blood to keep them running which in turn means greater heart rate which in turn means that more oxygen needs to be pumped by the lungs which in turn results in higher breathing rate.

Asthma is usually brought on by allergens in the environment, but respiratory tract infections caused by viruses have also been shown to cause asthma. Microbial infections can also eventually bring on asthma.

The partial pressure of oxygen (O2) determines how much oxygen can be delivered from the lungs to the blood. At higher altitudes the partial pressure of oxygen is lower and it is therefore harder to extract the oxygen from the air to bind with the hemoglobin. Because of the oxygen deficit as compared to sea level breathing rate increases.

Yes; this is correct.

keeps the trachea open when the head is bent or turned

These are called cilia.

The Respiratory membrane: The wall of the alveoli are composed primarily of a single layer of squamous epithelial cells, called type I cells, surrounded by a flimsy basement membrane. See page 815 anatomy and physiology 8th
