Why do we breathe at a particular combination of frequency and tidal volume?
Breathing frequency or respiratory rate is the rate at which breathing occurs. Normally it is 12-18 breaths per minute.
Tidal volume is the amount of air moved in or out of lungs during normal respiration. It is also called quiet breathing. And it is about 500ml in a healthy adult.
We usually breath at a particular frequency and TV so as to maintain a balance between the Oxygen inhaled and carbon dioxide produced in the body. This helps in intake of only the required amount of oxygen and thus keeping the production of carbon dioxide in check.
Why do we breathe at a particular combination of frequency and tidal volume?
6. If a subject has a breathing frequency of 20 breaths/minute and a tidal volume of 1200 mL, what is the person's minute volume? 7. Calculate the alveolar ventilation rate () for a subject with a breathing frequency of 16 breaths per minute, a tidal volume of 450 ml, and a dead space volume of 160 ml.
How and why would vigorous exercise cause changes in: tidal volume, total lung volume, residual volume, IRV, ERV and vital capacity? When answering this question use the knowledge from the lectures and your own thought process. Don’t get caught up trying to search web sites for answers and led astray into obscure scenarios. This is a straightforward question and marks will not be given for answers that do not follow the directions above
why do individuals who are anemic generally not exhibit an increase in respiratory rate or tidal volume even though their blood is not carrying enough oxygen ? please answer in own words
Which of the following is DECREASED when we increase tidal volume? a. PO2 in the lungs b. PCO2 in the veins c. PO2 in the tissues d. PCO2 in the lungs
Calculating minute,alveolar ventilation.
a dead space volume of 150 mL &breathes at a frequency (f) of 10 breaths/min using a tidal f Tory ha volume (V) of 650 mL. What is Tory's minute ventilation (V)? what is her alveolar ventilation (VA)? c. Tory decides to breathe through a straw (for fun) whose volume is 150 mL (yes, it is a good- sized straw). She is not breathing through her nose at all. If both f and V, remain constant, what...

Why are fine particulates dangerous to breathe? Do you feel that there should be a PM-2.5 standard? How would you go about enacting such a standard?

For a particular combination of capital and labor we know that the marginal product of capital is 6 units of output and that the marginal rate of technical substitution is 3 units of capital per unit of labor. What is the marginal product of labor? Explain.
Insects do not have lungs as we do, nor do they breathe through their mouths. Instead, they have a system of tiny tubes, called tracheae, through which oxygen diffuses into their bodies. The tracheae begin at the surface of the insect's body and penetrate into the interior. Suppose that a tracheae is 1.36 mm long with a cross-sectional area of 1.38 x 10-9m2. The concentration of oxygen in the air outside the insect is 0.796 kg/m3, and the diffusion constant...
