DALTON’S LAW OF PARTIAL PRESSURES

A

TOTAL PRESSURE FROM MIX OF GASES IS SUM OF THE PRESSURE THAT EACH GAS EXERTS INDEPENDENTLY

35
Q

HENRY’S LAW

A

WHEN GAS CONTACTS A LIQUID IT DISSOLVES IN THE LIQUID IN PROPORTION TO ITS PARTIAL PRESSURE

36
Q

4 COMPONENTS OF AIR BY PERCENTAGE (HIGHEST TO LOWEST)

A

NITROGEN, OXYGEN, WATER, CO2

37
Q

OXYHEMOGLOBIN

A

OXYGEN DISSOLVES IN BLOOD AND COMBINES WITH IRON ATOMS OF HEMOGLOBIN TO FORM THIS
CARRIES OXYGEN TO NEARBY CELLS WHO NEED IT

38
Q

WHAT HAPPENS WITH MOGLOBIN WHEN PH CHANGES

A

IF PH DECREASES, HB MOLECULES CHANGE SHAPE TO RELEASE OXYGEN MORE EASILY

39
Q

WHAT HAPPENS WITH HEMOGLOBIN AS TEMP CHANGES

A

IF TEMP IS INCREASED MORE OXYGEN IS RELEASED

40
Q

DIFFERENCE BETWEEN ADULT AND FETUS HEMOGLOBIN

A

MUCH LARGER AFFINITY FOR OXYGEN IN FETAL

41
Q
