Explanation:
Blood is one of the most important elements in life. Raghu as a student must know about it. Almost every animal that has a circulatory system has blood. From an evolutionary point of view, it has been hypothesized that blood arose from a type of cell that was responsible for phagocytosis and nutrition. Billions of years later, blood and the circulatory system drastically aided the evolution of more complex life forms.
Blood is a liquid connective tissue consisting of plasma, blood cells and platelets. It circulates throughout our body and supplies oxygen and nutrients to various cells and tissues. It makes up 8% of our body weight. An average adult holds around 5-6 liters of blood.
Raghu can ask to his teacher what are the types of blood cell which are discussed below:
Blood cell types
We have seen blood composed of cells known as blood-forming elements. These cells have their own roles and functions in the body. The blood cells that circulate throughout the body are as follows:
Red Blood Cells (erythrocytes)
RBCs are uninucleate biconcave cells in humans; Also known as erythrocytes. RBCs contain the iron-rich protein called hemoglobin; to give the blood its red color. RBCs are the most abundant blood cells produced in the bone marrow. Their main function is to transport oxygen to different tissues and organs.
White Blood Cells (leukocytes)
Leukocytes are colorless blood cells. They are colorless because they are devoid of hemoglobin. They are further classified as granulocytes and agranulocytes. WBCs mainly contribute to immunity and defense mechanism.
Raghu can also ask to his teacher that why our all blood is red whose answer is as follows:
RBCs contain hemoglobin (say: HEE-muh-glow-bin), a protein that carries oxygen. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs. As the blood travels through the body, the hemoglobin releases oxygen to the different body parts.
