OXYGEN TRANSPORT AND DIFFUSION
Transported through the blood in 2 different ways
1. 1.5% - dissolved in the plasma2. 98.5% - attached to Hb to form oxyhemoglobin
Hemoglobin
ERYTHROCYTES
Hemoglobin HemeRBC
● 4 irons/Hb → 250 million Hb/RBC → 1 billion O2/RBC● 98.5% O2 devliered via Hb
CARBON TRANSPORT AND DIFFUSION
Transported through the blood in 3 different ways
1. 7% - dissolved in the plasma2. 20% - attached to Hb to form carbaminohemoglobin3. 73% - reacts with water in the plasma → carbonic acid
