What can be counted to determine the rate of a person's breathing?
Respirations can be counted to determine the rate of a person's breathing. You need a clock or wristwatch with a second hand. Begin counting when the second hand reaches 12, and watch for when the person's chest rises during intake of a breath. Ignore exhalations. Count for a full 60 seconds.
Normal rate of respirations average around 18 to 20 breaths in one minute. Exercise can temporarily raise the rate into the low 20s. Stress or being excited or upset can increase the rate as well.
What happens when the pulmonary valve is malformed?
When the pulmonary valve is malformed, it forces the right ventricle to pump harder to overcome the obstruction
What is the part of the fish acts just like the diaphragm in the human respiratory system?
The gills act as the lungs intaking water and air and filtering back out again.
If you have a respiratory infection and you sweat does that mean that its breaking up?
To me, it means that you have a temperature and should take it easy for another day or so.
How does journaling help an operating system recover from system failures?
In a journaling file system -- such as ext3 or NTFS -- changes are written to a separate log - the journal - before being committed to the main storage area. This journal contains information about the intended changes.
In the event of power failure or system crash tools can compare the journal to the main file system and discover inconsistencies without walking the entire file system.

What causes breathing increase during a fight or flight response?
It is caused by the neurohormone called norepinephrine.
What is the meaning of aerobic and anaerobic respiration?
Aerobic respiration requires oxygen and Anaerobic respiration does not require oxygen!
Can a person hold their breath untill they die?
No. A person with incredible will power may be able to hold their breath until they pass out, but when this happens involuntary control will takeover and they will resume breathing
No. A person with incredible will power may be able to hold their breath until they pass out, but when this happens involuntary control will takeover and they will resume breathing
Holding your breath can't kill you. At most, you can pass out, and then you'll start breathing automatically.
Gaseous exchange takes place when the volume of the chest cavity is increased or decreased.
Why might aerobic respiration stop?
Aerobic respiration may stop due to a lack of oxygen, which is essential for the process to occur. Additionally, the accumulation of metabolic byproducts, such as carbon dioxide, can inhibit cellular functions. Other factors like nutrient depletion, damage to cellular components, or unfavorable environmental conditions can also lead to the cessation of aerobic respiration.
What are the two phases of breathing?
The two phases of breathing are breathing in and breathing out. Humans breathe in oxygen and they release carbon dioxide when they breathe out.
An alveous is an air sack ath the the end of each stem thing in the lung. They are surrounded by cappilaries. The air is stored in the alveoli and an diffusion occurs of the oxgen moving through the thin wall of the alveolus into the blood and the carbon dioxide moving into the alveolus and then the carbon dioxide is brethed out
