How do you calculate tidal volume in a cat?
Tidal volume is the total amount of air in your lungs that is inhaled/exhaled at one point. Tidal volume is found by using a machine to calculate it. Or, it is:Insiratory reserve volume+expiratory reserve volume+tidal volume+residual volume.REVISIONYour definition of tidal volume is correct...it is the amount of air that moves in or out of the lungs during normal inspiration or expiration, but the equation you gave (IRV + Vt +ERV + RV) is for Total Lung Capacity.I don't believe that there is an equation to calculate tidal volume. It can be calculated, however, by subtracting your average ERV (expiratory reserve volume) from your average EC (expiratory capacity). Using a spirometer, perform the procedure to get your expiratory capacity. Do this 3 times and figure the average. Then perform the procedure to get your expiratory reserve volume and repeat 3 times to figure your average. Then, as I mentioned in the 1st line of this paragraph, subtract your average ERV from your average EC.
How can you explain that air has weight?
Experiments which can prove that air has mass and therefore weight abound, but I'll give a simple thought experiment here which indicates that air must be massive. Assume that the atmosphere of the earth has some pressure P at the surface of the planet (reasonable, as many homes have barometers which measure just that), and determine what the pressure will be at other altitudes. Pressure exerts a force proportional to the value P and the surface area A of the face of the volume you are considering out of the volume, this is its definition. If that force is not balanced by another force on the face of that volume then the air will reapportion itself until the forces are balanced, which will lead to a different pressure. If air has no mass then the force of weight does not contribute to the overall force on any volume of air, and it can only be balanced by an equal pressure immediately above it. This is true of any volume of air, not just those at the surface. Thus we see that if air had no mass then the atmosphere would have to extend throughout all space to remain pressurized at a fixed value. Since this is clearly not the case according to repeated measurements of atmospheric pressure at altitude, as well as being contradicted by the many space missions which have been performed, air must be massive.
What is the air chamber of the egg?
Just before hatching begins, the air cell expands to approximately 30% of the internal volume of the egg. As hatching begins, the beak of the embryo penetrates the inner shell membrane where it forms the inner wall of the air cell. The lungs begin to function, inhaling the air from the air cell.
Why are some egg whites thicker than others?
As you whisk them you are putting air into them,much like inflating a tire.
1 milligram equals how many millileters?
It depends on what you are measuring. 1 mg of gold will have a much smaller volume than 1 mg of air. 1 mg of water at 4 degrees Celsius occupies almost exactly 1 ml.

What type of air is residual volume?
residual volume is the amount of air left in your lungs after fully exhaling.
The air remaining in the lung after a maximal expiration is the?
residual volume
Which volume of air is not included in the vital capacity?
residual (reserve) volume
The lungs contain a certain amount of air that cannot be forced out the volume of air is known as what?
this is called residual volume.
The amount of air that can no be exhaled is called?
The residual volume is the volume of air remaining in the lungs after the most powerful expiration.
What is meant by residual volume with reference of breathing?
Exhalation is a passive action that results from elastic recoil and changes in air pressure. When this happens naturally a portion of air remains within the lungs- residual volume. However when exhalation is forced, that is conscious efforts to expel as much air as possible, many of the residual volume can be forced out of the lungs.
The amount of air remaining in the alveolus after expiration is referred to as what?
residual volume
What is the difference between tidal volume and residual volume and pulmonary?
Tidal volume is the volume of air that moves in and goes out in asingle stroke, and is abut 500ml.
What is the amount of air remaining in the lungs even after the greatest possible expiratory effort?
residual volume
What is the medical term meaning stale air in the respiratory tract?
The residual volume is the portion of air in the respiratory tract that cannot be exhaled.
What is the functional residual capacity FRC composed of?
Functional Residual Capacity (FRC) = Expiratory Reserve Volume (ERV) + Residual Volume (RV)
Air remaining lungs after forced expiration?
The air that can not be exhaled is called residual volume.TV = the amount of air displaced during normal breathing.IRV = The amount of air that can be taken in forcibly beyond tidal volumeErv= The amount of that can be expelled forcibly.Vital capacity = the total amount of exchangeable air.Total Lung capacity = TV + IRV + ERV + RESIDUAL VOLUME
