RBC (Red Blood Cells)
RBC’s are also known as Erythrocytes. They are biconcave and are present without a nucleus in human beings. It contain Haemoglobin which is an iron-rich protein due to which the color of blood is red. RBC’s are produced in the bone marrow which is mainly responsible for the transportation of oxygen to and from various tissues and organs present in the human body.
WBC (White Blood Cells)
WBC’s are also known as Leucocytes which are colourless blood cells due to the absence of haemoglobin. They are further divided into two categories such as granulocytes and agranulocytes. Their main responsibility is to provide immunity and maintain defence mechanisms in the human body.
