Once released from the bone marrow into the circulation, the average life span of a red blood cell is about

4 months (120 days)

In a red blood cell, carbon dioxide is attached to the

Amino acids of the globin

Platelet plug formation is initiated when platelets come into contact with

Collagen fibers in the connective tissue beneath the endothelium

Red blood cells do not use any of the oxygen that they carry, because

They lack mitochondria to use oxygen for aerobic respiration
