Mammalian RBC is always enucleated [Without nucleus] without any EXCEPTION The mammalian RBC is also biconcave and DISCOIDAL except Camel and Llama, which have Oval shaped RBC
ques is wrong.....all mammals including camels and llamas have non nucleated RBCs.
RBC of all the mammals is anucleated without any exception. RBC of mammals are nucleated only during embryonic stages. It's just that RBC's of camels and llama are oval in shape and anucleated.
RBCs in reptiles are nucleated.
Yes they do
Nearly all non-mammal vertebrates have nucleated red blood cells (nRBC). Non-nucleated RBC's are a unique feature to mammals. There are of course a few notable exceptions, such as the artiodactyl order, which have an odd blood morphology.
camels have nucleus in their RBC's.
red blood cells that have not lost their nucleus.
After RBC are fully developed they lose their nucleus. This gives them more room to hold hemoglobin but they can not divide and die after 120 days.
The red blood cells of all mammals, without exception, are anucleated (lacking a nucleus). Mammal RBCs are nucleated only during embryonic stages. The red blood cells of camels are oval instead of round so they can withstand the effects of water deprivation better.
no they are not all nucleated
It doesn't, not normally. The normal erythrocyte of any camelid (camels, llamas, alpacas) is oval-shaped with no nucleus. Birds have nucleated, oval-shaped RBCs. Perhaps that is what you are thinking of.
Yes, birds have nucleated red blood cells.
