Blood is a fluid-like structure that is responsible for transporting oxygen and other nutrients to all the cells of the body. Blood shows characteristics of both tissues and fluid.
Blood is composed of the below-mentioned parts:
The two types of blood cells present in the body are:
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’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.
