if you breath in naturally, without forcing in extra air, then expire all the air you can out of your lungs, the total volume is
The volume of air inhaled naturally without force is the tidal volume. The amount of air that can be exhaled from the lungs beyond what is exhaled with a normal exhalation when one performs a forced exhalation is the expiratory reserve volume.
Thus, the total volume = tidal volume + expiratory reserve volume.

On a chilly 12∘C day, you quickly take a deep breath--all your lungs can hold, 4.0 L. The air warms to your body temperature of 37∘C. If the air starts at a pressure of 1.0 atm, and you hold the volume of your lungs constant (a good approximation) and the number of molecules in your lungs stays constant as well (also a good approximation), what is the increase in pressure inside your lungs?
Which of the following best describes tidal volume? options: 1.The amount of oxygen in the air at sea level. 2.The maximum volume of air that can be moved in and out of the lungs with forced breathing. 3.The volume of air moved in and out of the lungs with each breath while at rest. 4.The amount of oxygen picked up by the blood with every breath.
On a cold day, you take a breath, inhaling 0.4 L of air whose initial temperature is -10 degree C. In your lungs, its temperature is raised to 37 degree C. Assume that the pressure is 106 kPa and that the air may be treated as an ideal gas. What is the total change in translational kinetic energy of the air you inhaled number? Round your answer to the nearest whole.
You draw in a deep breath on a chilly day, inhaling 3.6 L of 0∘C air. If the pressure in your lungs is a constant 1.0 atm, how much heat must your body supply to warm the air to your 37∘C internal body temperature? Assume that for air Cp = 29.1 J/(K⋅mol) as it consists mostly of nitrogen
Estimate the volume flow rate (in units of m'/s) of the air that fills your lungs as you take a deep breath. volume flow rate: x10 m3/s
Which measure of ventilation is the maximal amount of air that can be moved in and out of the lungs with forced inhalation and exhalation? A) vital capacity B) forced expiratory volume C) tidal volume D) total lung capacity 53. Which of the following increases the affinity of oxygen to hemoglobin? A) iron B) heme C) myoglobin D) magnesium 54. Which of the following refers to cellular deprivation of oxygen? A) hypoxemia B) hypercapnia C) hypoxia D) all of these...
Estimate the volume flow rate (in units of m'/s) of the air that fills your lungs as you take a deep breath. volume flow rate: 1 x 10 m3/s
Tidal volume is _____ The amount of air remaining in the lung after expiration The volume of air that moves in (and out) of the lungs in a single breath The amount of air that remains in the airways after expiration The volume of air that the lungs can hold when maximally inflated Atmospheric pressure The exchange of oxygen and carbon dioxide between the lungs and the blood is called ____ Pulmonary ventilation External respiration Internal respiration Cellular respiration expiration...
For most people (of normal density) the following is true: While in a pool, if you take a deep breath and hold it - you float. If you exhale all of the air out of your lungs - you sink. Explain why this is so.
Joe Smith is a 69-year-old male with a 50-year history of
smoking 2 packs of cigarettes a day (i.e. 100-pack-year smoking
history). Over the past 5 years, he has become increasingly short
of breath. At first, he noticed this only when exercising, but now
he is even short of breath at rest. Over the past two years, he has
had several bouts of lower respiratory tract infection treated
successfully with antibiotics. His shortness of breath hasn't
subsided, and his breathing...
