Question

Red blood cells appear to be elliptical or elongated. In which species would these be considered normal RBCs?

1) Canine
2) Camelid
3) Feline
4) Avian

Answer 1

Avian red blood cells are elliptical or elongated.

Step-by-step explanation:

In mammals, including humans, red blood cells do not have a nucleus and are usually biconcave disc-shaped.

However, in some species, such as avian (birds), red blood cells have a different shape.

Avian red blood cells are elliptical or elongated.

Therefore, the correct answer is option 4) Avian.
