The RV
Which chamber usually compresses first with cardiac tamponade
RA
what does CO2 bind with in the Hb
The amine group
Define the haldane shift

What three forces move water into the capillary
Hydrostatic pressure of capillary
Hydrostatic pressure of tissue

At what level is the accessory hemiazygos and hemiazygos
Hemi - T9 descending
Accessory - T8 ascending
The DRG receives sensory info from what
Glossopharyngeal and vagus N.
What are the progenitor cells of the heart
Endothelial cells
A Tet of FALLOT IS CHARACTERIZED BY WHAT
VSD, overiding Ao, and RVH
What is the equation to calculate Alv. O2
PAO2 = [(760 - 47) x 0.21] - O2 Consumed
The O2 consumed is determined by RQ and Co2 Produced in the equation :
RQ = (CO2 Produced [PaCO2]/(O2 Consumed) - rearrange to find O2 consumed
What is the A - a gradient and the equation
The amount of Oxygen lost from alv. To pul. arteries
A high number is very bad - lots of O2 stored in alv. And not reaching lungs
Equation: PAO2 - PaO2

Mitral valve insufficiency
The apex of the heart has what type of PaO2 compared to the base
Increased
Decreased blood flow to Alv means what will happen to PAO2
It will equalize to inspired air
What is the most important control for normal quiet respiration
pH in central chemoreceptors
