The volume of air which you normally breathe in and out is called the tidal volume. This is normally about 500 cm3 when you are at rest. However if you breathe in as much as you can you can breathe in more than 500 cm3. The extra volume of air breathed in (inspiration) is called the inspiratory reserve volume.Similarly when you breathe out as much as you can, the extra volume of air breathed out (expiration) is called the expiratory reserve volume. These three volumes added together give you your vital capacity: the maximum volume of air you can breathe in or out. When you have breathed out as much as you can there is still some air left in your lungs ie you cannot empty your lungs completely. This volume is called the residual volume.The vital capacity plus the residual volume equals your total lung capacity.

What else can I help you with?
How does cotton keep you warm when wet?
Cotton when wet exhibits a capillary effect and wicks much water into its volume. It does not keep you warm.
How does changing the substrate concentration exhibit the same effect as changing the enzyme concentration?
For the enzyme to work, its particles must collide with the particles of the substrate. The more particles there are per unit volume, the more frequent the collisions will be. Thus changing the concentration of either chemical will have the same effect.
What is the effect on the volume of a substance when thermal energy is added?
Adding heat to something generally increases its volume. In rare cases, adding heat to something like ice may actually decrease its volume. The increase in volume of a heated gas is much more significant than the increase in volume when solids and liquids are heated.
A cubic centimeter is a unit for measuring what?
A cubic centimetre (cm3) is a unit of volume (V).
If a beaker had 160 liters of water what is the volume?
Liters is a measurement of volume. 160 Liters is the volume.
What is the medical term meaning the amount of air that can be inspired above the tidal volume?
Inspiratory reserve volume is the volume you can inhale past the normal tidal volume.
How do you do capacity?
It's the inspiratory reserve volume plus the tidal volume plus the expiratory reserve volume
What is the approximate volume of inspiratory reserve volume?
The average inspiratory reserve volume (IRV) for adults is around 3,000-3,500 mL. This volume represents the maximum amount of air a person can inhale beyond their normal tidal volume during a deep breath. It is an important component of lung capacity and respiratory function.
What are the volumes that makes up vital capacity?
Expiratory reserve volume, tidal volume, inspiratory reserve volume, you amateurs
How can one determine the inspiratory reserve volume in the lungs?
To determine the inspiratory reserve volume in the lungs, you can measure the maximum amount of air a person can inhale after a normal inhalation. This can be done using a spirometer, a device that measures lung capacity and function. The inspiratory reserve volume is the additional air that can be inhaled beyond the normal tidal volume.
Typical value in ML for inspiratory reserve volume?
3000ml
What are the three volumes that make up vital capacity?
Expiratory reserve volume, tidal volume, inspiratory reserve volume, you amateurs
Which respiratory air volume has the largest volume?
Inspiratory Reserve Volume
What is the amount of air called you can inhale above tidal inspiration?
The amount of air you can inhale above tidal inspiration is called inspiratory reserve volume (IRV). It represents the additional air you can breathe in after a normal inhalation.
How does emphysema affect IRV?
Emphysema damages the alveoli in the lungs, leading to decreased elasticity and impaired gas exchange. This results in a loss of lung volume and an inability to fully expand the lungs during inhalation. Consequently, the Inspiratory Reserve Volume (IRV) is reduced, as patients have difficulty taking in additional air beyond their normal tidal volume. This limitation contributes to the overall respiratory difficulties experienced by individuals with emphysema.
What is inspiratory reverse volume?
Inspiratory reverse volume is the volume of air that remains in the lungs after maximal inspiratory effort. This can happen in conditions where the lungs are hyperinflated, like in chronic obstructive pulmonary disease (COPD). It can lead to inefficient breathing and decreased exercise tolerance.
What is the amount of air beyond tidal volume?
The amount of air beyond tidal volume is known as the inspiratory reserve volume (IRV) and expiratory reserve volume (ERV). Inspiratory reserve volume is the additional air that can be inhaled after a normal tidal inhalation, while expiratory reserve volume is the air that can be exhaled after a normal tidal exhalation. Together, these volumes contribute to the total lung capacity and are crucial for assessing respiratory function.
