The movement of chloride ions into erythrocytes from the plasma to maintain osmotic balance during transport of gases is known as

Select the correct option:
$(1)$ Approximately $97\%$ of $O_2$ is transported by plasma / RBCs.
$(2)$ The primary site of gas exchange is alveoli / bronchioles.

Which of the following factors is favourable for the formation of oxyhaemoglobin in the alveoli of human lungs?

The Hamburger phenomenon is also known as:

If $ppCO_2$ is high and pH is low,then it will result in:
$i$. increase in affinity of haemoglobin for $O_2$
$ii$. decrease in affinity of haemoglobin for $O_2$
$iii$. oxygen dissociation curve shifts to left
$iv$. causes release of $O_2$ for diffusion into tissue cells
$v$. $H^+$ and $HCO_3^-$ ions combine to form carbonic acid

Describe: Transport of $CO_{2}$.
