“It transports oxygen and gives it a red colour”. That’s the answer you will likely get to an ordinary student if you ask them question about what haemoglobin is. But I tell you, ask that to a medical technology student, she’ll probably not only answer that to you but also add some information about haemoglobin like “it is composed of two heme and two globin chains”. Did you know that haemoglobin has high molecular weight which is 68,300 Daltons? Also the amount of haemoglobin per red blood cell is 640 million, (which basically makes you a billionaire by blood! Imagine how many rbc you got on your body) Haemoglobin’s affinity to oxygen was first described by Felix Syler in 1862. Oops, are these trivias to many? Apparently no. the study of blood cells or hematology is really wide. As a medical technology student, the subject hematology is divided into two: Hema 1 and Hema 2.
Being a student of medical technology really needs guts and enough knowledge about blood cells. And by the way, I haven’t introduced white blood cells and platelets. White blood cells or leukocytes are our defenses in our body. Once our body detects foreign materials, phagocytes, a wbc, circulate and look for that infection. These wbc are like patrols or cops who looks for that infection and take specific action. They belong to the marginating pool. Did you know that some white blood cells have granules? Yes. Apparently these pieces of information are facts. On the other hand, platelets of thrombocytes forms clot to prevent further damage and bleeding once you are cut or injured. These are some of the wonders our blood on our body makes.
In hematology, expect to have deeper understanding about the different blood cells, how they are produced, their lifespan, functions and their abnormalities (yes! They also have abnormalities) and how it affects one’s body. Not only that, this specific subject also informs you about different hematologic procedures or known on layman’s terms as blood tests, like CBC, hematorit, reticulocytes count, ESR and many more. Also, you will discover in this subjects about the diseases associated to our blood like anaemia, leukaemia and many more together with its underlying causes and effects.
