A
- start with a picture so …. step one is draw > > > three times on a piece of paper label each one in order (top to bottom) 1..2..3
- Ask your self what pressures are always stronger artery or venous.. duh artery. this means Pa will always go before PV in every zone!!
- Next starting in zone 1 write PA First b/c we know the alveoli pressure is the highest here
- Next right PA in the middle of zone 2 b/c as we go down zones Alveoli pressure decreases
- next place PA in the last spot in Zone 3 b/c it is now the least pressure
- Ok now go back and fill in the Pa and PV values in teh empty spots. *** remember in every zone arterial pressure is always higher than venous
