Transport of Gases

The carbon dioxide is transported via blood to lungs as:

CO₂ is transported through the blood to the lungs in the form (s) as

The oxygen $-$ haemoglobin dissociation curve will show a right shift in case of

${\mathrm{CO}}_2$ is dissolved in haemoglobin or blood plasma as

Acquiring an oxygen debt is evidence that

Oxygen is transported to every cell of the body through

What is the maximum number of oxygen atoms that a molecule of haemoglobin can bind?

A sigmoid curve is obtained when percentage saturation of hemoglobin $\left(\mathrm{Hb}\right)$ with oxygen is plotted against the ${\mathrm{PO}}_2$ as indicated below:

If a patient who is a hypothermic with a body temperature of $30°\mathrm{C}$ the curve shifts towards

Left side shift of oxygen-haemoglobin dissociation curve occurs during

Which of the following statement is correct?

Which statements are true/false?

(i) Blood transports ${\mathrm{CO}}_2$ comparatively easily because of its high solubility.

(ii) Approximately $8.9\%$ of ${\mathrm{CO}}_2$ is transported dissolved in plasma.

(iii) ${\mathrm{CO}}_2$ diffuses into blood, passes into $\mathrm{RBCs}$, and reacts with water to form ${\mathrm{H}}_2{\mathrm{CO}}_3$.

(iv) Oxyhaemoglobin of erythrocytes is basic.

 (v) Chloride ions diffuse from plasma into erythrocytes to maintain ionic balance.

The amount of oxygen present in one gram of haemoglobin is

What is true about $\mathrm{RBCs}$ in humans?

Percentage of oxygen being carried by blood plasma is

Dissociation curve of O₂ (which is dissociation from Hb) shifts to the right when

Bicarbonate formed inside erythrocytes moves out to plasma while chloride of plasma pass into erythrocytes. The phenomenon is called

Haemoglobin is

Exchange of gases in lung alveoli occurs through

In carbon monoxide poisoning there is
