Respiratory Health -Transport. of Blood Gases

Name the ways oxygen can be transported in the blood

Physically dissolved in the plasma

Chemically bound to the haemoglobin molecule in the red blood cells

What is the Bohr effect?

Bohr effect increases the delivery of oxygen to tissues

How: 

Increased H+ increases acidity and H+ bind to Hb molecules, which increases the dissociation of oxyhemoglobin, releasing 02 to the tissues.

What does the shifting of the oxyhemoglobin dissociation curve to the right mean?

The Bohr effect Affinity decreases, Unloading of O2 to the tissues

How does Carbon Monoxide affect Oxygen transport in the blood?

The affinity of Hb for carbon monoxide is 240 times that of 02

How is carbon dioxide transported in the blood?

Physically dissolved

Combines with Hb as carbaminohaemoglobin

Chemically combined as bicarbonate ion

What’s the difference between the Bohr effect and Haldane effect

The Bohr effect helps the metabolizing tissues release oxygen from oxyhemoglobin while the Haldane effect helps the lungs release carbon dioxide from carbaminohemoglobin
