Question

what is a colour of RBC ?

Answer 1

Answer:

Human red blood cells take on average 60 seconds to complete one cycle of circulation. The blood's red color is due to the spectral properties of the hemic iron ions in hemoglobin. Each hemoglobin molecule carries four heme groups; hemoglobin constitutes about a third of the total cell volume.

Answer 2

An RBC is pale red and gets its color from hemoglobin. It's shaped like a doughnut, but it has a thinner area in the middle instead of a hole. Your RBCs are normally all the same color, size, and shape
