Gas Exchange and Transport

Oxygen is carried in the blood bound to hemoglobin called ______________.

oxyhemoglobin

What two ways is oxygen transported through the blood?

1) as a dissolved gas in the plasma 2) bound to the heme moiety of hemoglobin

Carbon dioxide is also bound to hemoglobin, and when it does, it’s called _________________.

carbaminohemoglobin

What three ways is carbon dioxide transported through the blood?

1) as a dissolved gas in the plasma 2) bound to polypeptide chains of hemoglobin 3) as HCO3- in red blood cells

Both oxygen and carbon dioxide move _____ their pressure gradients.

down

Fresh air comes in and mixes with old air which makes values of O2 and CO2 in the alveoli ________ from the amount of air coming in.

different

Partial pressure of oxygen is ______ in the blood than it is at the tissues.

higher

The partial pressure of carbon dioxide is ______ in blood than it is at the tissues.

lower

Since partial pressure of carbon dioxide is lower in the blood than the tissues, the carbon dioxide will move ____ the blood from the tissues.

into

Since partial pressure of oxygen in the alveoli is ______ than the partial pressure of oxygen in blood, oxygen moves into ______ to be distributed.

greater, blood

Since the partial pressure of carbon dioxide in the alveoli is _____ than the carbon dioxide in the blood, carbon dioxide will move into _____ to be exhaled.

less, alveoli

Majority of carbon dioxide travels by ________ in the plasma of the blood.

bicarbonate

The majority of oxygen travels by binding to the _____ ______ of the hemoglobin.

heme moiety

Both oxygen and carbon dioxide participate in ________ reactions for transport.

reversible

The formula for oxygen transport is ___ + ___ ⇌ ___-__

Hb, O2, Hb-O2

The formula for carbon dioxide transport is ____ + _____ catalyzed by carbonic anhydrase ⇌ _____ ⇌ ______ + ___

CO2. H2O, H2CO3, HCO3-, H+
