If the animals are not closely related, but the structures are meant to serve the same function (structure determines function!) then the structures are analogous. The difference between analogous and homologous is that in analogous structures, the creatures are not closely related but the structure serves the same purpose (like bat wings/bird wings) and homologous structures are similar structures directly as a result of ancestry.

The sickle-cell disease is characterized by red blood cells with sickle shape (like a semi-circle). The iron-containing pigment, HEMOGLOBIN in these sickle-shaped red blood cells is
- inefficient in transporting oxygen
- likely to break down in environment with low oxygen concentration.
Such abnormally shaped red blood cells block the cavities of small blood vessels like CAPILLARIES, hindering the free movement of healthy, normal oxgen-carrying blood in them.
