WebErythrocytes, or red blood cells ( RBCs ), are the most common blood cells. Normal RBCs have a biconcave shape and contain hemoglobin but no nucleus or organelles.

WebLoss of CO2 through exhalation coaxes any CO2 bound to hemoglobin to release and be exhaled. When CO2 is dumped, O2 can be picked up. Indirect loss of H+ coaxes any H+ bound to hemoglobin to release in order to make H2CO3, which then becomes CO2 and H2O and is also exhaled.

Web13 nov. 2024 · Haemoglobin is a protein comprised of four subunits: two alpha subunits and two beta subunits. Each subunit has a haem group in the centre that contains iron and binds one oxygen molecule. This means each haemoglobin molecule can bind four oxygen molecules, forming oxyhaemoglobin. WebThe oxyhemoglobin dissociation curve reflects the relationship between the oxygen saturation of hemoglobin and the partial pressure of arterial oxygen. It can shift depending on various factors, but if we look at the reasons behind how the body delivers oxygen to the tissues, we can discern the different triggers.
