Everyone thinks blood means red, doesn't it? In fact, the color of the blood may or may not be red. The color of the blood depends on the composition of the blood.When I was a child, I heard that the lizard's blood was white and I had never tested it. About 45% of the blood that flows through every artery, vein and blood network in our body is cells and the remaining 55% is plasmaThere are three types of plasma - red blood corpuscle, white blood corpuscle (WBC corpuscle) and platelets.The red blood cells look like discs and are biconcaveBut these cells do not have a nucleus like other living cells. Instead, they contain hemoglobin, each hemoglobin molecule is made up of proteins called heme and gobinHeme contains an iron ion that is encased in a complex inorganic substance. This iron ion picks up oxygen molecules from the lungs and carries them to living cells.The amount of red blood cells in our blood is high, so the color of our blood also looks red. There is no such thing as having more red blood cells in our blood. Just as most vertebrates have more red blood cells, so most insects have more white blood cells. And so their blood is white. But what is meant by white is their blood, but not exactly white. Their blood actually has no color. So many people confuse the color of their blood with the color of their skin. That is why it is seen that when mosquitoes are killed, blood is not seen all the time. The blood that goes red is actually human blood. Which the mosquito absorbed from the human body for nutrition.
