How are red blood cells adapted to do their job?

Autor: yxng.edxn



Respuesta:

They're shaped like a biconcave disc to give them a larger surface area for absorbing oxygen. They don't have a nucleus, so this maximizes the amount of oxygen they can carry. They contain a red pigment called hemoglobin which binds to oxygen, becoming oxyhemoglobin.
