Ch 17 Respiratory (Cn)

Front 1

Define pulmonary ventilation

Back 1

is the process of breathing-inspiration (inhaling air) and expiration (exhaling air)

Front 2

Define external respiration

Back 2

is the process of gas exchange between the lungs and the blood.

Front 3

Define internal respiration

Back 3

is the process of gas exchange between the blood the interstial fluid and the cells. Inside the cell, cellular respiration generates energy (ATP), using O2 and glucose and porducing waster CO2.

Front 4

Give Boyle's law

Back 4

describes the relationship between the pressure (P) and the volume (V) of a gas. The law states that if the volume increase, the the pressure must decrease

Front 5

Give Dalton's law

Back 5

states the the sum of the partial pressure of each gas in a mixture is equal to the total pressure of the mixture

Front 6

Give Henry's law

Back 6

the greater the partial presssure of a gas, the greater the diffusion of the gas into the liquid.

Front 7

Charles' law

Back 7

If a volume is held constant, pressure is proportional to temperature

Front 8

Define Tidal Volume (TV)

Back 8

The amount of air inspired during normal relaxed breathing, about 500ml.

Front 9

Define Inspiratory Reserve Volume (IRV)

Back 9

Is the additional air that can be forcibly exhaled after the expiration of a normal tidal volume, about 3,000ml.

Front 10

Define Expiratory Reserve Volume (ERV)

Back 10

is the additional air that can be forcibly exhaled after the expiration of a normal tidal volume, about 1,200ml.

Front 11

Define Residual Volume (RV)

Back 11

is the volume of air still remaining in the lungs after the expiratory reserve volume is exhaled, about 1,200ml.

Front 12

Define Total Lung Capacity (TLC)

Back 12

Is the maximun amount of air that can fill the lungs, about 6,000ml. TLC=TV+IRV+ERV+RV)

Front 13

Define Vital Capacity (VC)

Back 13

Is the total amount of air that can be expired after full inhaling, about 4,800ml. (VC=TV+IRV+ERV=approximately 80% TLC)

Front 14

Define Inspiratory Capacity (IC)

Back 14

is the maximum amount of air that can be inspired, about 3,600ml. (IC=TV+IRV)

Front 15

Define Functional Residual Capacity (FRC)

Back 15

is the amount of air remaining in the lungs after a normal expiration (FRC=RV+ERV)

Front 16

Define Inspiration

Back 16

Occurs went the inpiratory muscles-that is the diapragm and the external intercostal muscles contract.

Front 17

Define Expiration

Back 17

Occurs went the diaphragm and external intercostal muscles relax.

Front 18

Give the properties of O2 as it applies to gas exchange

Back 18

The partial pressure of o2 in the lungs is high, but solubility is poor.

Front 19

Give the properties of CO2 as it applies to gas exchange

Back 19

The partial pressure of COs in the air is extremely low, but its solubility is 24 times that of O2.
