Question

What are the adaptations of RBC as the carrier of oxygen

Answer 1

RBC [Red Blood cells] transport Oxygen for aerobic respiration.

Function:RBC  absorbs the O2 in the lungs and passes through narrow blood vessels and releases O2 to Cells .
To perform their Function RBC's have adaptations :

--> Hemoglobin:
RBC contain Hemoglobin which combines with Oxygen.

---> Absence of nucleus:
As they have no nucleus, They can mix with more hemoglobin.

-->They are small and flexible in nature which make them pass through narrow blood vessels.

--> They have Biconcave shape :
The biconcave surface maximizes the surface area to carry more amount of O2.
