What is the composition of DRY AIR (as split into N2, O2, and CO2?

[...] O2 extracted from blood/min and consumed by tissues/min

... CO2 produced per min and expired/min

The Respiratory quotient is

Pressure of a gas is proportional to

According to Dalton's Law, partial pressure it the pressure of a specific gas based on what?
What is the total pressure?

The driving force determining the rate of gaseous transfer/diffusion is?

What is diffusion limited by?

Transfer rate is equal to

In regards to pressure difference and solubility, how do O2/CO2 differ?

Systematic blood PO2 is determined by?

Alveolar pCO2 is determined by

In most cases, transfer of gases and rapid and equilibirum is reached .... of the way along pulmonary capillary

Why is systematic arterial pO2 slightly lower than alveolar pO2?

What are 4 measures of oxygen transport?

How many protein subunits is haemoglobin made of? What do each of these subunits contain?

Why is haemoglobin needed for blood transport?

What are the three factors influencing the structure of Hb?

The Hb disassosiation curve shifts LEFT when what happens to the following:

Where does this happen and what happens to affinity?

The Hb disassosiation curve shifts RIGHT when what happens to the following:
pCO2
pH
Temp
2,3 DPG
Where does this happen and what happens to affinity?

What are the 3 forms of CO2 transport in the blood?

What are the two ways CO2 is transported as bicarbonate?

What speeds up the reaction of CO2+H20-->H2CO3-->H+HCO3?

The Chloride Shift forms the PCO2 gradient in RBC by

Haldane Effect A creates the pCO2 gradient in RBC by

How is the pCO2 gradient formed in the RBC? (3)

How does Haldane Effect B create the pCO2 in RBC for carboaminos?

The Haldane Effect states that at any pCO2, quantity of CO2 carried in venous blood [...] arterial blood because

How does the pCO2 gradient in lungs relate to the gradient in blood? Why?

The Gap in the CO2 disassosiaton curve represents the...
