They also contain very few organelles

Mature RBCs circulating in the blood are litterly bags of hemoglobin molecules

Hemoglobin an iron bearing protein transports most of oxygen that is carried in the blood

It also binds with a small amount of carbon dioxide

Question 9

Since Erythrocytes lacks

Answer 9

Mitochondria and makes atp by anaerobic mechanisms, they do not use up any oxygen they are transporting,making them very efficient oxygen transporters

Question 10

When number of RBC increases

Answer 10

Blood viscosity or thickness increases
