Hemoglobin

Hemoglobin (also spelled haemoglobin, abbreviated Hb or Hgb), is the iron-containing oxygen-transport protein present in red blood cells (erythrocytes) of almost all vertebrates (the exception being the fish family Channichthyidae) as well as the tissues of some invertebrate animals. Hemoglobin in blood carries oxygen from the respiratory organs (lungs or gills) to the other tissues of the body, where it releases the oxygen to enable aerobic respiration which powers the animal's metabolism.

But hemoglobin does not work without memes in the body, so here is a good meme!

And no content would be perfect without a random sample video!

After the sample video we sitlll need some images though...

And a quote!

And a second video is also very  important to test!

That's it folks!
