If we say that blood is a vital liquid, red coloured fluid that circulates in the vessels and consists of cells, we would have made a definition that everyone knows. It is derived from the Latin word Hema, and the branch of science that studies blood is called Hematology. The origin of the word ‘hema’ comes from the Greek word “haima”. To talk about blood cells; can be divided into 3 as red blood cells, white blood cells and platelets. Blood has the functions of defence, transport, regulation and protection in our body. Blood groups, on the other hand, are classifications made by looking at the antibodies in their structure.

Only female mosquitoes bite to suck blood, which they use to make their eggs, and the same goes for horseflies, deer flies and black flies. Because biting flies’ bloodlust is a function of their reproduction cycle (and most complete only one generation per year), the risk of being bitten is only significant during certain times of the year — mating season, basically, mainly in the spring. Also, the intensity of their attack can vary from year to year depending on that season’s brood.
