How oxygen is transported in the blood

oxygen concentration is higher in lungs(alveoli) that in blood

oxygen in the alveoli dissolves in the film of moisture and diffuses through thin epithelial and capillary walls into plasma and red blood cells

the oxygen combines with haemoglobin to form oxyhaemoglobin

blood then becomes oxygenated

blood from lungs then travels to all body tissues where the oxyhaemoglobin breaks down to form oxygen and haemoglobin

haemoglobin is transported back to the lungs to collect more oxygen while the oxygen in capillaries diffuses into body cells for respiration

respiration produces carbon IV oxide

How Carbon IV Oxide is transported in the blood

carbon IV oxide produced during respiration diffuses out of cells into blood plasma and red blood cells due to concentration gradient

carbon IV oxide and water fonn carbonic acid carbamino compounds with haemoglobin

in the presence of carboxyl anhydrase enzyme, hydrogen carbonate is carried in blood to the lungs

in the lungs the hydrogen carbonate dissociates to liberate carbon IV oxide which diffuses into alveolar cavity due to concentration gradient

from alveolar space carbon IV oxide is expelled during expiration

Most carbon IV oxide is transported from tissues to lungs within the red blood cells and not in the blood plasma. Give the advantages of this mode of transport.

PH of blood is not altered/homeostasis is maintained

Within the red blood cell is an enzyme, carbonic anhyrase which helps in fast loading(combining) and offloading of carbon (iv) oxide
