What is Hematology?
Blood is made up of several components such as red blood cells, white blood cells, platelets, and plasma. It is via red blood cells that oxygen is delivered to the lungs and tissues throughout the body. Red blood cells account for around 45 percent of total blood volume. Carbon dioxide is also transported back to the lungs through the mucus membranes of the respiratory tract. In the bone marrow, they are formed into discs, which is how they get their name. The bone marrow’s function is to create white blood cells that aid in the fight against infection. Together with platelets, they account for less than one percent of total blood volume. Platelets are small, colourless particles that cling to one another and interact with clotting proteins to stop or prevent bleeding from occurring. They are also produced by the bone marrow.
