Explanation:

$7 % {CO}_{2}$ is dissolved in plasma, $20 - 25 %$ is carried by $RBC$ .

BIOXI17: BREATHING AND EXCHANGE OF GASES

338981 Read the following statements:
I. Nearly $25 %$ of ${CO}_{2}$ is transported as carbaminohaemoglobin in RBCs.
II. In the alveoli, where there is high ${pO}_{2}$ , low ${pCO}_{2}$ lesser $H^{+}$ concentration and lower temperature, the factors are favourable for breakdown of oxyhaemoglobin.
III Every $100 mL$ of oxygenated blood delivers $15 mL$ of $O_{2}$ to tissues during strenuous exercise.
IV. With increase in body temperature during exercise, the affinity of haemoglobin for oxygen increases.
Which of the above statements are correct?

Explanation:

In the alveoli, where there is high ${pO}_{2}$ , low ${pCO}_{2}$ lesser $H^{+}$ concentration and lower temperature, the factors are favourable for formation of oxyhaemoglobin. With increase in body temperature during exercise, the affinity of haemoglobin for oxygen decreases.

BIOXI17: BREATHING AND EXCHANGE OF GASES

338982 A large proportion of oxygen is left unused in the human blood even after its uptake by the body tissues. This $O_{2}$

1 Acts as a reserve during muscular exercise

2 Helps in releasing more

3 Is enough to keep oxyhaemoglobin saturation at

96 %

4 Raises the
