So, blood is not just blood… This is a good thing to learn, which I didn’t know before reading this blog.
Just one question, although I think I guess the answer correctly (but better to ask the expert to be sure ;) ). In fact, just two related questions...
You mentioned that animals have 4 respiratory pigments in their blood. Do they all have 4 pigments, or do they have up to four pigments? Similarly, do animals always have a given type of white blood cells, or could their blood feature admixtures of several types of white blood cells? Thanks in advance for answering me!
Cheers and have a good week!
They have different pigments. All the four pigments cannot be in one animal. It is the varying pigments that gives their blood different shades of colour - green, yellow, violet etc on the other hand we humans have majorly red colour conferred by haemoglobin.
Regarding the white blood cells, definitely theirs vary from that is humans though not Much. In animals, theirs is mostly called haemocytes (also function like wbc in Humans) case in point animals that have a closed circulatory system (blood system made up of a heart pumping Blood through blood vessels) like Humans but in none mammals.
In summary, animals have similar wbc as humans depending on specie and secondly the difference can easily be detected through their quantity. Wbc in animal are more abundant than in humans, just the way glucose is found more in the plasma of an animal than in humans.
Thanks for those clarifications. They are perfect and allow me to adjust how I thought about the situation.
Cheers!
