Solution

The correct option is B oxygenation
The process of addition of oxygen to an atom or a molecule in order to increase the concentration of oxygen in tissue is generally referred to as oxygenation. When the bulk of oxygen diffuses from the plasma into the red blood corpuscles where it joins loosely with Fe2+ ions of haemoglobin (Hb) to form bright red oxyhaemoglobin (HbO2) it is also an example of oxygenation.
So, the correct answeris 'oxygenation'.

(3) The carbon dioxide produced by the tissues,diffuses passively into the blood stream and passes into red blood corpuscles and react with water to form

.
(4) The oxyhaemoglobin(

(5) The chloride ions diffuse from plasma into the erythrocytes to maintain ionic balance.

Q. Why are red blood corpuscles and plasma called suspensions?

Blood is red in colour. Oxygen-rich blood is bright red as it leaves the heart. When it returns to veins without oxygen, it turns blue. Does it mean that the haemoglobin is turned off in the absence of oxygen?

Q. Assertion :A rise in PC

O_{2}

, H+ ions and temperature shifts the Hb

dissociation curve to right. Reason: A rise in PC

O_{2}

or fall in pH decreases oxygen affinity for haemoglobin.

Q. Usually chordates have red blood containing red blood corpuscles. The blood is red due to the presence of the following pigment.
